About the Role

Platform Engineering is the backbone of Trade Republic's engineering velocity. Our mission is to build scalable platforms for a Europe-scale bank — serving internal engineers, and building in-house control planes for managing the bank's infrastructure. The Backend Reliability team builds and owns Trade Republic's most critical backend systems — the services that process every trade, every payment, every savings plan. This is a software engineering role first: we believe the best reliability work happens at the code level, not the runbook level.

Responsibilities

  • Design and implement new backend services and platform components in Kotlin — high-throughput, low-latency, fault-tolerant by design.
  • Define and drive SLOs, model failure modes during design, implement circuit breakers, bulkheads, graceful degradation, and retry strategies directly in the application layer.
  • Design and run load tests, stress tests, and chaos experiments against critical backend services.
  • Define best practices for service design, error handling, resiliency patterns, and safe deployment.
  • Model traffic growth, identify performance bottlenecks across the application and data layer, and own the engineering work that keeps systems performant ahead of demand.
  • Own post-mortems for critical service failures and ensure findings close real gaps.
  • Define and implement structured logging, distributed tracing, and alerting standards for critical backend services.

Requirements

  • 5+ years of hands-on backend software engineering experience, with deep ownership of production systems at scale.
  • Strong programming skills in Go, with experience building infrastructure automation as software rather than scripts.
  • Proven experience building resilient, high-throughput distributed systems.
  • Experience with load testing, performance profiling, and capacity planning at scale.
  • Familiarity with event-driven architectures and distributed data systems in production.
  • A track record of raising engineering standards.
  • Production experience with container orchestration and modern infrastructure.
  • Strong incident command and post-mortem skills.
