Full Stack Developer
Build across the entire stack — Java Spring Boot services, PostgreSQL, and a Next.js + React frontend — on the platform that meters and bills the AI economy.
What you'll do
- Own product areas end-to-end — from database schema through Spring Boot service to the React UI a customer actually clicks
- Ship features real customers use, not tickets from a backlog — if you see something broken, you fix it
- Move fast without breaking billing — write the migration, the test, the observability, and the runbook, then hit deploy
- Set the engineering bar with the founding team: code review culture, on-call maturity, testing discipline, and the story your production tells at 2am
- Build SDKs and integrations (Node, Python, Java, Go, Kong, Apigee, AWS, Azure, MuleSoft) that give customers a five-line integration path
What you need
- 3+ years of production full-stack experience — you have shipped code and owned the outages
- Strong Java + Spring Boot — you know why Spring Data JPA does what it does and when to reach past it
- Comfortable in React + TypeScript — hooks, state management, and the fact that Next.js server components are a different beast
- SQL fluency — schemas, indexes, and the reason both matter when the billing pipeline processes a million events a day
- A track record of shipping to production, owning the on-call, and getting better afterwards
Nice to have
- Prior work at a billing, payments, fintech, or infrastructure company
- Real open source contributions — not just a stars-heavy GitHub profile
- Startup experience — you know how to move fast without breaking the customer
- Familiarity with gateway plugins, event streaming (Kafka / Redpanda), or metering SDKs
Compensation: Competitive salary + meaningful early-stage equity + you own real product surface from day one
