About the role

We’re looking for a Senior Backend Engineer to join our Wallet product team — the team that owns and develops our custodial wallet, a core part of the app’s financial experience.

Your mission is to make the Wallet solid, unified, and pleasant to use — improving stability, polishing existing flows, and supporting the delivery of new capabilities that provide real value to our users.

You’ll be the backend engineer in a cross-functional team (Owner, Product Manager, Design, Web, Mobile, QA, AQA). Together with them you will: • Refine and stabilize existing flows, improving usability and reliability, • Deliver new wallet functionality that enhances client experience, • Bring coherence and consistency to wallet logic where it directly improves UX and team velocity.

This role is for someone pragmatic, comfortable juggling shifting priorities, and able to balance quick UX fixes with building long-term quality — without falling into large rewrites.

Job description

• Design, build, and maintain backend services for our custodial wallet using Go, Postgres, Kafka, Redis, gRPC, and OpenAPI. • Improve and refine existing wallet flows together with Web and Mobile engineers — identifying where quick frontend fixes help and where backend/API adjustments are needed. • Deliver new wallet capabilities that improve the overall experience for our users and support evolving product needs. • Ensure coherence and consistency across wallet logic and APIs where it directly improves UX, system behavior, and development speed. • Apply engineering best practices: idempotent and backward-compatible APIs, safe and reversible schema changes, clear rollback paths, observability-first mindset. • Own the full lifecycle of backend changes: discovery, design, implementation, review, rollout, monitoring, and incident handling. • Collaborate with platform and infrastructure teams to reuse shared components and paved roads, ensuring alignment across the backend ecosystem. • Participate in technical planning and help the team break down work into small, predictable, and high-quality deliverables.

Qualifications

You have:

4+ years of backend engineering experience, including solid experience with Go or a similar systems language. • Strong understanding of Postgres, Kafka, Redis, transactions, concurrency, and distributed systems basics. • Experience designing and evolving service APIs (gRPC and/or REST/OpenAPI) with a focus on backward compatibility and smooth client integration. • Ability to work with complex product flows: improving existing logic, identifying weak points, and delivering safe, incremental improvements. • Comfort being the only backend engineer in a cross-functional product team — making technical decisions, explaining trade-offs, and owning delivery end-to-end. • Strong focus on reliability, data consistency, and correctness — critical for any custodial wallet. • Pragmatic engineering mindset: knowing when to refactor, when to optimize, and when a simple fix is enough to unblock the product. • Clear communication skills and willingness to collaborate closely with product, design, frontend, QA, and platform teams.

Highly preferred:

• Experience in fintech, payments, wallets, or other high-integrity transactional domains. • Familiarity with Kubernetes, observability tooling (Prometheus, Grafana, Jaeger, Kibana), and production debugging. • Background improving performance or reducing latency in backend systems. • Experience working in fast-moving product teams with shifting priorities. • Understanding of reporting/analytics patterns (exposing safe aggregated data, designing read-efficient APIs).
