Finding the Opportunities

Look beyond big job boards. Pipeline programs are your best farm system: apply for JAX Hub, which places graduates into pilot projects, or seek mentorship through initiatives like Jax Code 4 Change. Engage with the local scene at events hosted by OneSpark or through networking groups like LaunchClub.

Evaluating Stability (The Scout's Due Diligence)

In interviews, move beyond the ping-pong table. Ask specific questions about mentorship structure and code review processes. To assess a startup's health, consider these factors:

• Runway & Revenue: Ask about burn rate and the path to profitability. Revenue is more sustainable than pure venture capital.
• Team Growth Signals: Check LinkedIn to see if team size is growing month-over-month. Consistent hiring is a positive indicator.
• Founder & Tech Lead Vision: Their answers about handling failure and developing talent reveal more about your potential growth than any perk.

Choose the startup committed to coaching your mechanics and giving you real ownership. That’s where you’ll find not just a job, but a career-defining at-bat, building the domain expertise that defines success.
