Resistant AI

Among Prague’s AI players, Resistant AI stands out as one of the most-funded startups focused on defending financial systems. Its products scan transactions and documents for manipulation and fraud, putting real money and regulatory risk behind the models you help ship. In rankings of Czech AI companies, it consistently appears near the top, including in Digest.pro’s overview of AI startups in Czechia, which highlights its Series B status and global client base.

Why it works for juniors

For a first or second role, the appeal is the mix of seriousness and access. A Series B company means:

• Processes and code review are in place, so you’re not alone in chaos.
• Teams are still small enough that a junior can own features end-to-end.
• You see production ML used by banks, fintechs, and payment providers, not just demo apps.

Sitting in Prague puts you close to regional offices of big financial institutions while still benefiting from Czechia’s lower cost of living compared with Western capitals.

What you’ll actually build

Day to day, junior engineers tend to work around:

• Data and backend services in Python/Java ecosystems, with SQL/NoSQL and cloud platforms.
• ML ops pipelines that get models from experiments into monitored production.
• Integrations into customer systems and APIs, often under titles like “Junior Software Engineer,” “Data Engineer,” or “ML Engineer - Graduate” on boards such as Glassdoor’s Czech junior listings.

  Compensation and what to ask

  You can expect offers roughly in line with the Prague junior market, often around 45,000-60,000 Kč/month gross, with 5 weeks dovolená, sick days, meal vouchers, and Multisport as typical perks. In interviews, go beyond the “top AI startup” branding and ask concrete questions about:

  • Runway: months of cash post-Series B at current burn.
  • Customer base: how many banks or fintechs are in long-term contracts.
  • Mentorship: how many seniors you’ll work with directly in your team.

Productboard

Productboard sits in that sweet spot between scrappy startup and heavyweight SaaS platform. Built as a product-management system used by teams worldwide, it runs major engineering hubs in Prague and Brno and regularly shows up in ecosystem maps such as StartupBlink’s overview of 800+ Czech startups, where it’s listed among the country’s flagship tech companies.

Why it’s a strong first tram line

Compared with tiny seed-stage teams, Productboard gives juniors clearer structure without burying them in corporate bureaucracy. You get:

• Defined paths from junior to mid-level with regular feedback cycles.
• Squads where PMs, designers, and engineers work closely, so you learn product thinking, not just ticket execution.
• A choice between Prague’s big-tech ecosystem or Brno’s university-driven scene, where rent and living costs are still lower.

What you’ll actually touch

Most junior roles focus on modern SaaS engineering:

• Frontend development with TypeScript and React on complex dashboards.
• Backend services in JVM or Node.js languages, plus cloud-native infrastructure.
• Internal tooling and integrations that keep the platform attractive to large customers.

On Czech and international job boards you’ll usually see titles like “Junior Frontend Engineer” or “Associate Backend Developer,” often grouped under graduate or early-career tracks.

Compensation, benefits, and how to prepare

Salaries for juniors are typically competitive with Prague’s tech market and often a step above smaller startups, with Brno packages adjusted to its lower cost of living. Expect standard benefits: five weeks of dovolená, sick days, meal support, and usually some stock options.

If you’re coming from a bootcamp, Productboard pairs well with structured paths like Nucamp’s 16-week Back End, SQL and DevOps with Python program (tuition around 48,852 Kč) or its 25-week Solo AI Tech Entrepreneur track (about 91,540 Kč), which help you build the full-stack and AI-assisted workflows that modern product teams now expect.

Kiwi.com

Kiwi.com is one of Central Europe’s best-known travel-tech exports, famous for its “virtual interlining” that stitches together routes from different carriers into a single booking. It shows up consistently in rankings of Prague and Brno startups, including Failory’s list of Prague startups to watch, which highlights its scale and engineering-heavy culture.

Why Kiwi.com works for juniors

As a first or second job, Kiwi.com offers something many early-career developers never see: high-traffic, high-stakes systems from day one. You work on search, pricing, and routing logic that handles millions of queries, forcing you to think about performance, caching, and failure modes early in your career.

• A long track record of hiring graduates from Brno and Prague universities makes it more “junior-ready” than many newer startups.
• Brno gives you lower living costs and a compact tech scene; Prague connects you directly to global airlines and partners.
• Teams are used to mentoring people into production work rather than parking them on toy projects.

Tech focus and junior roles

Engineering spans backend search and booking services (often JVM, Node.js, or Python backgrounds), frontend work on complex UIs, and data-heavy domains like pricing optimisation, fraud detection, and A/B testing. Junior titles to watch for include “Junior Backend Developer,” “Associate Data Engineer,” or “Junior Frontend Engineer” across Czech and international job boards.

Compensation and how to stand out

For Brno-based roles, junior salaries often land in the upper part of the 45,000-60,000 Kč/month range, with Prague positions slightly higher, plus standard Czech tech benefits. To stand out, arrive with hands-on experience in web backends and data tooling - structured paths such as a 16-week Back End, SQL and DevOps with Python bootcamp (around 48,852 Kč) or a 15-week AI Essentials for Work program (about 82,386 Kč) can help you demonstrate real projects rather than just theory.

Rohlik Group

Rohlik Group grew from a Czech online supermarket into what many analysts now call Central Europe’s largest e-grocery player, with operations across multiple EU markets. It also increasingly shows up in tech-focused rankings, such as Tracxn’s overview of Czech high-tech startups, where it is listed alongside more “classic” software companies thanks to its heavy investment in engineering and automation.

Why Rohlik fits an ambitious junior

For early-career developers, Rohlik offers the rare mix of unicorn-scale stability and startup-like speed. Almost every part of the business is a software problem: real-time inventory, routing vans through Prague’s streets, automating warehouses, processing payments, and personalizing offers for different markets. As a junior, you’re not just building screens - you’re touching systems that directly influence delivery times and margins.

Typical stacks and junior roles

Engineering teams are spread across backend, web, and mobile, plus data and ML groups working on forecasting and recommendations. Common junior titles include “Junior Backend Developer,” “Junior Mobile Developer,” and “Junior Data Engineer,” with work that may involve:

• APIs for ordering, logistics, and partner integrations.
• Consumer and courier apps for iOS/Android and web.
• Data pipelines and models for demand prediction and basket personalization.

Pay, perks, and questions to ask

Rohlik typically matches the Czech junior market with salaries around 45,000-60,000 Kč/month plus performance bonuses, alongside benefits like extended dovolená, meal vouchers, employee grocery discounts, and Multisport. In interviews, push for specifics on how juniors are used: do you own features in a product squad, or mostly fix bugs in legacy systems? Also ask how engineering is organized across countries - whether you’ll work on Czech-only features or pan-European platforms that boost your long-term career options.

BottleCap AI

BottleCap AI operates like a compact foundation-model lab tucked into Prague’s startup grid, focused on building and optimizing large language models with an almost obsessive emphasis on efficiency. It appears regularly in overviews of Czech AI ventures as one of the most ambitious younger players, sitting alongside names like Resistant AI in lists of top AI-focused startups in the country. In a landscape where AI is eating much of the old junior “grunt work,” this is one of the rare teams actually inventing the tools everyone else will use.

Why this kind of lab fits certain juniors

Early-stage AI startups look for juniors who behave more like peers than students: you’re expected to experiment independently, debug complex systems, and use AI tools as leverage, not crutches. For the right personality, BottleCap AI offers:

• Direct exposure to cutting-edge LLM research and productionization without leaving Prague.
• Very small, technical teams where motivated juniors can influence architecture and product direction.
• Equity upside that can matter if the company lands the right enterprise customers.

Day-to-day work and stack

Typical junior responsibilities cluster around three areas:

• Training and fine-tuning language models using Python and deep-learning frameworks on GPU infrastructure.
• Building and maintaining infra/DevOps for fast, reliable inference and evaluation.
• Creating tooling, dashboards, and developer-facing APIs with TypeScript/React plus backend services.

Compensation, investors, and hard questions

Early-stage AI labs often sit at or slightly below the Czech junior baseline, with BottleCap AI likely offering around 45,000-60,000 Kč/month in cash compensated by stock options. When you interview, probe their runway (months of cash at current burn) and backing: reputable local funds such as Credo, KAYA, and Presto appear among the dozen most active investors in Czech software according to Seedtable’s overview of Czech VCs. Ask concretely how juniors are used: are you just running prompt experiments, or will you own and ship pieces of the platform that real customers pay for?

Langtail

Langtail sits in Prague’s AI corridor as a developer platform focused on making LLM-powered applications safer and more reliable. Instead of building yet another chatbot, it helps teams test, monitor, and evaluate their existing LLM features in production. It’s highlighted among the startups “pushing innovation forward” in Czechia in EU-Startups’ 2026 overview of the local ecosystem, where its Seed-stage backing from Credo Ventures and Presto Ventures is noted as a sign of serious technical ambition.

Why it’s a smart bet for juniors

For early-career engineers, Langtail offers leverage in three directions:

• You learn LLM evaluation, observability, and guardrails - skills every AI product team now needs, regardless of sector.
• Small, engineering-led squads mean juniors can own real pieces of the platform rather than only chasing bug tickets.
• A track record of hiring “Product Engineer Interns” and junior devs who show strong side projects gives you a clearer entry path than many stealth AI labs.

Tech stack and day-to-day work

The stack is intentionally grounded in familiar web tools: TypeScript/Next.js and Node.js for the product surface, with Python for AI integrations and evaluation backends. Juniors typically:

• Design and ship full-stack features for prompt experimentation, regression testing, and analytics dashboards.
• Integrate new LLM providers and tools into the platform.
• Improve developer experience for customers instrumenting their own AI apps.

The team is active at Prague JavaScript and AI meetups listed on dev.events’ calendar of Prague developer meetups, which is often where internships and junior roles surface first.

Compensation, runway, and what to ask

As a Seed-stage startup, Langtail’s junior salaries usually sit in the lower half of the 45,000-60,000 Kč/month range, balanced by equity and flexible hybrid or remote options. When interviewing, ask directly whether they have at least 12-18 months of runway, how quickly they plan to expand the engineering team, and how many seniors you’ll pair with in your first six months. Also review their GitHub and public changelogs - they “build in public,” which gives you concrete material to discuss in interviews and shows how they think about real-world LLM failures.

Veeam Software

Veeam Software is a global name in backup and data protection, and Prague is one of its key engineering hubs. While it’s far from a garage startup, it regularly appears in Czech “high-tech and startup” rankings and competes for the same talent as younger fintech and AI players. For someone starting out in Czechia, Veeam is effectively the infrastructure-heavy counterpart to the flashier SaaS and AI brands on the tram board.

Why it’s a solid first infra role

Early in your career, few places will teach you as much about reliability as a backup company serving enterprises. At Veeam you’re exposed to:

• Real-world high-availability patterns and disaster recovery scenarios.
• Enterprise customers who care about compliance, SLAs, and predictable releases.
• Teams that operate like product units within a larger organization, giving you structure but also a sense of ownership.

What you’ll work on as a junior

Most junior roles centre on the Microsoft stack and supporting tooling. Typical titles include “Junior C#/.NET Developer,” “QA Automation Engineer,” and occasionally frontend or tooling roles. Expect to spend your time on:

• Designing and implementing REST APIs and backend services in C#/.NET.
• Building automated test suites and harnesses that keep large codebases stable.
• Improving internal tools used by support and customer-success teams.

Compensation, benefits, and what to look for

Veeam usually offers salaries in the middle to upper band of Czech junior roles, around 45,000-60,000 Kč/month in Prague, along with 5 weeks dovolená, sick days, meal vouchers, and a training budget for certifications. You’ll often find its openings listed among international employers on Built In’s Czechia tech jobs board.

In interviews, ask which specific product or component you’d join, how old the codebase is, and what the release cadence looks like. If you want a more “startup-like” experience inside Veeam, target smaller, greenfield projects or platform teams where juniors can contribute to new features instead of only maintaining legacy modules.

Tatum

Tatum has carved out a niche as a blockchain development platform that lets teams add Web3 capabilities through APIs and SDKs instead of wrestling with node infrastructure. From its base in Prague and Brno, it serves developers across Europe and beyond, consistently appearing in Czech fintech and high-tech startup rankings as one of the country’s better-known Web3 players.

Why Tatum is interesting for juniors

For early-career engineers, Tatum is less about speculative tokens and more about durable platform skills. You learn to think in terms of:

• API design that other developers depend on for production apps.
• Security and reliability across multiple blockchains.
• Developer experience: docs, SDKs, and tooling that remove friction.

Because the company operates out of both Prague and Brno, you can choose between the capital’s broader ecosystem and Brno’s university-driven scene and slightly lower living costs.

Stack, roles, and where jobs appear

Most junior roles sit around backend services and tooling. Expect to see stacks built on JavaScript/TypeScript plus at least one systems or backend language (often Java or Go), plus knowledge of REST, webhooks, and auth flows. Titles include “Junior Backend Developer,” “SDK Engineer,” or “Developer Relations Engineer (Junior),” and they sometimes surface on startup-focused boards like TopStartups’ Prague job listings.

Compensation, stability, and due diligence

Junior salaries typically land in the Czech market band of 45,000-60,000 Kč/month, often paired with equity or token-based incentives. When you evaluate an offer, look for:

• Evidence of recent funding rounds in the 2024-2025 window and who the lead investors are.
• Recurring revenue from enterprise or long-term clients, not just one-off pilots.
• Clarity on how much of your time will touch the core platform versus experimental side projects.

Those signals tell you whether Tatum is a Web3 hype play or a real platform where your early-career work will live for years.

Choice

Choice (often branded as Choice or ChoiceQR) builds QR-powered menus, ordering, and marketing tools for restaurants and cafés. It’s a classic B2B SaaS story rooted in Prague’s hospitality scene, but with a product footprint that now spans multiple European markets. In recent ecosystem roundups it’s been ranked 1st in the “Software & Data” category among Czech startups to watch in 2026, a sign that it has moved well beyond scrappy pilot projects into mainstream adoption.

Why this vertical SaaS fits juniors

For an early-career developer, Choice offers fast feedback and tangible impact. When you ship a feature on Monday, you can see it live in real restaurants by Friday. That short loop helps you quickly understand:

• How real-world businesses map to data models (tables, reservations, payments).
• What happens when hundreds of guests hit the same QR code during Saturday brunch.
• How bugs and UX issues surface in front-of-house staff under pressure.

Stacks, roles, and where to find openings

Most roles cluster around web and mobile flows that handle menu browsing, ordering, payments, and loyalty. Expect stacks based on TypeScript/React (or similar), mobile frameworks, and backend services integrating payment providers and analytics. Job titles like “Junior Frontend Developer,” “Junior Backend Developer,” or “Implementation Engineer” often pop up on local boards such as Jobs.cz’s Prague junior listings.

Pay, stability, and how to vet them

Junior salaries for B2B SaaS in Prague typically land around 45,000-60,000 Kč/month, with dovolená, meal vouchers, and Multisport as standard perks. To assess stability, look for visible customer logos and case studies, and check whether they’ve been through respected accelerators listed in Failory’s guide to Czech accelerators and incubators (programs like StartupYard or JIC are strong signals). In interviews, ask how much of your work will be on core product versus custom features for large clients; that balance determines how reusable your experience will be at your next “tram stop.”

Duvo AI

Duvo AI sits at the intersection of retail and automation: an AI-native platform that helps shops keep shelves stocked, prices tuned, and staff schedules aligned without endless spreadsheet firefighting. Based in Prague with a remote-friendly setup, it’s one of the newer names that keep appearing alongside Resistant AI and Langtail when investors talk about Czech AI startups to watch in 2026.

Why it’s compelling for juniors

Retail is a great training ground because problems are concrete and measurable: either products are on the shelf or they’re not; either a promotion works or it doesn’t. For a junior developer, Duvo AI offers:

• Exposure to production-grade AI applied to inventory, pricing, and workforce planning.
• Early-team learning, where motivated juniors can quickly become go-to people for a domain.
• Remote or hybrid work options that widen your choices beyond Prague and Brno city centres.

Typical roles and stack

Most junior roles cluster around data and backend engineering. Expect to see titles like “Junior Data Engineer,” “AI Engineer - Entry Level,” or “Junior Full-Stack Developer,” working with Python-heavy data pipelines, forecasting models, and TypeScript-based dashboards that plug into retailers’ POS and ERP systems.

Compensation, backing, and due diligence

Early-stage AI startups in Czechia tend to cluster around 45,000-60,000 Kč/month for juniors, with equity and performance bonuses making up part of the package. Before accepting an offer, check whether Duvo AI has live “anchor” customers (for example, regional retail chains) and which funds are backing them. Surveys of the local investor scene, such as DEPO Ventures’ overview of Czech startup investors on LinkedIn and ecosystem reports like Talent.ai’s deep dive on Czech innovation, can help you map how serious their supporters are.

How to use this Top 10 like a Prague tram map

Standing at Anděl with the drizzle in your face, the departure board only becomes useful once you know where you’re trying to go. This Top 10 works the same way: it shows you what’s arriving soon in Prague and Brno, but the “right” tram depends on the skills and experience you want to collect over the next few years.

Decide what you want to learn

Before you fixate on a brand name, translate each company into a learning path. Ask yourself whether you want to grow into:

• an AI/ML specialist (Resistant AI, BottleCap AI, Langtail, Duvo AI),
• a product-minded full-stack or frontend engineer (Productboard, Choice, Tatum),
• or an infrastructure and data reliability person (Veeam, Rohlik, Kiwi.com).

Once you know the destination, the ranking turns from noise into a shortlist.

Hunt where juniors are actually hired

The usual job portals only show part of the picture. Many early-stage teams quietly post on startup-focused boards or hire from meetups and referrals. Overviews such as Nexus IT Group’s guide to startup job platforms highlight places like StartupJobs and niche boards where Czech founders actively look for junior talent. For data roles in Brno, even a quick scan of “data junior” searches on sites like Jooble’s Brno listings can reveal which companies are open to training newcomers.

Evaluate like an investor, move like a tram rider

When you talk to any of these startups, think like a small VC: check who invested, when they last raised, how they make money, and whether juniors get real mentorship instead of just tickets. Then move like a local on the tram network: pick a line that’s moving, ride it long enough to learn the system, and don’t be afraid to transfer later as your skills - and Czechia’s AI ecosystem - branch out in new directions.
