Job summary

Breakneck Studio is looking for a Founding Engineer to own features end-to-end—from database schema through the server, UI, and analytics. You will shape architecture across Postgres, Supabase, and Cloudflare Workers, and integrate third‑party APIs for flights, hotels, payments, and subscriptions.

You will work directly with the founders, influence technical direction as an early hire, and help scale a fast-growing travel-tech platform while exploring OpenAI and related tooling.

Qualifications

• 3–7 years shipping production web apps, ideally at seed/Series A startup.
• Comfort being the only engineer on a feature, handling end-to-end work.

• Design and evolve Postgres schemas with Supabase and RLS policies.
• Integrate 3rd-party APIs (flights, hotels, payments) with auth and webhooks.
• Build and refine LLM-powered tooling and tool-calling within the orchestration layer.
