Sr. Full-Stack Developer (Rails + React)

Were hiring a Senior Full-Stack Developer (Rails React)!

Summary

• Flexible Title: Can tailor to reflect your skills & experience.
• Flexible Time: Can do full-time part-time side-gig (off-hours) or fractional (contract).
• Flexible Commitment: Can do short-term long-term or intermittent.

Why so flexible Were a FUNDED startup racing to launch end of Q2 2026. That gives us just 3 months to stack features while raising additional working capital. Feel free to jump in help us ship then bounce >> or stick around. A successful launch translates into lots of permanent jobs for those that want them. Were also interested in long term side gig relationships if thats what youre into - in our experience a few expert hours often beat full-time learning-curve hours.
