YES LORVENS SOLUTIONS PVT LTD

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
