- Design and maintain a resilient ledger and state machine for money movement

- Implement a policy engine for approvals, caps, timelocks, and joint accounts

- Ensure performance, reliability, and observability across production systems

---

What We’re Looking For

- 5+ years building backend systems at scale

- Strong skills in TypeScript/Node, Go, Rust, or Kotlin

- Experience with async I/O, queues, retries, state machines

- Database expertise (Postgres, Redis) and modeling for consistency

- Track record of owning systems end-to-end (from design to production)

- work from Hyderabad

- Bonus: experience with crypto custody/MPC, Bitcoin UTXOs, or fintech/payment systems.
