Job description

About our product

We are building the first seedless Bitcoin wallet : secure, simple, and fully recoverable. No seed

phrases, no hardware hassle, no custodial risk. We use Bitcoin-native MPC to combine

sovereign-grade security with everyday usability, so customers can set up in seconds and trust

their Bitcoin for life.

We’re looking for a staff / founding backend engineer to help us build the foundations of a

smooth, reliable, and secure wallet experience, applied to the future of Bitcoin.

What you’ll do

  • Design and build low-latency APIs and realtime services that make sends, swaps, and

approvals feel instant.

  • Own backend integrations with partners (e.g., Turnkey, OneBalance), including secure

    • webhooks, retries, and idempotent flows.

  • Implement a policy engine for approvals, caps, timelocks, and joint accounts.
  • Build a resilient ledger and state machine for money movement with full auditability.
  • Deliver push-based updates (websockets / SSE) for a snappy mobile UX.
  • Define and uphold performance budgets : p95 <150ms for core APIs, near-realtime event

    • streaming.

  • Instrument, monitor, and debug production systems with OpenTelemetry, structured logs,

    • and metrics.

  • Collaborate closely with product and frontend engineers to make the UX buttery-smooth.

    • What we’re looking for

  • 5+ years building backend systems that serve consumer-facing products at scale.
  • Deep skill in at least one systems language (TypeScript / Node, Go, Rust, Kotlin)
  • Someone who can lead and design end to end architecture
  • Strong sense of ownership and leadership skills
  • Strong command of async I / O, queues, retries, and state machines.
  • Experience designing idempotent money movement flows (or equivalent critical

    • workflows).

  • Database fluency (Postgres, Redis) and data modeling for consistency (sagas, outbox,

    • dedupe).

  • Comfort with API design, schema versioning, pagination, and event streaming.
  • Solid instincts for security, privacy, and compliance in sensitive domains.

    • Bonus

  • Exposure to fintech / payments (ledgers, reconciliation, card rails, treasury systems).
  • Experience with crypto custody or MPC services (e.g., Turnkey, Privy, onebalance.io)
  • Understanding of Bitcoin UTXO basics or stablecoin mechanics.
  • Prior work on policy / rules engines or joint / multi-party account flows
  • Strong debugging chops : tracing, profiling, and fixing performance bottlenecks.

    • Requirements

  • Someone who can work full time from our office in Hyderabad, India
