We are hiring a Senior Backend Engineer for two platform products:

• →

  5+ years of commercial backend development

• →

  Go: idiomatic code, concurrency (goroutines, channels, context and cancellation), memory and performance profiling (pprof)

• Relational databases (PostgreSQL, MySQL): schema design, indexes, query plans, transactions and isolation levels, safe migrations

• Caching (Redis): when to cache, invalidation, consistency trade-offs

• Service architecture and distributed-systems trade-offs: consistency, availability, idempotency, retries, failure modes

• Asynchronous messaging and event-driven design (Kafka, RabbitMQ or NATS): delivery guarantees, ordering, reprocessing

• Designing REST and gRPC APIs: versioning, backward compatibility, contract documentation (OpenAPI / Swagger, Protobuf)

• Application security: common vulnerability classes (OWASP Top 10), secrets management, safe handling of user data

• OAuth 2.0 / OIDC from the server side: flows, tokens, sessions

• Containers and orchestration (Docker, Kubernetes) at the level of deploying and debugging your own services

• Observability (we use Datadog; experience with Prometheus, Grafana, ELK / Graylog or OpenTelemetry also counts): metrics, logs, tracing and alerting; diagnosing incidents in production

• Testing: unit, integration, contract

• Git, CI/CD (GitLab CI or similar)

• Daily hands-on use of AI coding tools (Claude Code, Codex, Cursor) for development and review, including configuring them for a repository

• Decisions in writing. Significant technical decisions are written up as an RFC or ADR that lays out the options and trade-offs. We discuss the document, not a blank whiteboard.

• AI is part of everyday engineering. We use AI coding tools for development and review, and we treat configuring them for a codebase as real engineering work.

1. Intro call. Your background, your motivation and the role.

2. Technical interview. Built directly on the What you will own and Required sections above. We won't ask about anything this posting doesn't promise.

3. Bar raiser. An engineer from outside the hiring team checks that you raise the overall engineering bar.

You will work alongside product managers, designers, backend and frontend engineers, QA and DevOps.

• Location: Remote (worldwide)

• Employment Type: Full-time

• Schedule: 10:00–19:00 (flexible)

• Contract: Employment agreement (entity or EOR arranged per candidate location)
