We have a bold mission to empower everyone to build wealth with easy safe and free access to financial systems. You will have the opportunity to grow your career by collaborating with a team of outstanding talents and state of the art technology to build a lasting positive future for millions.

ABOUT PLATFORM ENGINEERING

Platform Engineering is the backbone of Trade Republics 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 banks infrastructure. Were a 50-person Platform team focused on one thing: enabling product engineers to move fast and operate autonomously by default.

Within Platform Engineering our Backend Reliability team builds and owns Trade Republics most critical backend systems the services that process every trade every payment every savings plan. We write production Kotlin ship new capabilities and hold the reliability bar for the entire platform. This is a software engineering role first: we believe the best reliability work happens at the code level not the runbook level.

WHAT YOULL BE DOING

• Build core backend systems: Design and implement new backend services and platform components in Kotlin high-throughput low-latency fault-tolerant by design. You are a hands-on engineer who ships production code not just reviews it.
• Own reliability as a first-class engineering concern: Define and drive SLOs model failure modes during design implement circuit breakers bulkheads graceful degradation and retry strategies directly in the application layer reliability built in not bolted on.
• Lead load and chaos testing: Design and run load tests stress tests and chaos experiments against critical backend services. Translate findings into concrete architectural improvements and engineering standards the broader team adopts.
• Set and enforce backend engineering standards: Define best practices for service design error handling resiliency patterns and safe deployment and work directly with engineering teams to raise the bar across the platform.
• Drive scale and capacity engineering: Model traffic growth identify performance bottlenecks across the application and data layer and own the engineering work that keeps systems performant ahead of demand.
• Lead incident response and turn failures into better software: Own post-mortems for critical service failures and ensure findings close real gaps in architecture test coverage observability or deployment practices.
• Make observability first-class: Define and implement structured logging distributed tracing and alerting standards for critical backend services and hold product engineers to them through code review and design collaboration.

WHAT WERE LOOKING FOR

• 5 years of hands-on backend software engineering experience with deep ownership of production systems at scale. You write code every day and are proud of what you ship.
• Strong programming skills in Go with experience building infrastructure automation as software rather than scripts.
• Proven experience building resilient high-throughput distributed systems you have strong intuitions around backpressure failure isolation consistency trade-offs and what resilient-by-design means in practice.
• Experience with load testing performance profiling and capacity planning at scale youve designed test scenarios interpreted results and turned them into architectural decisions.
• Familiarity with event-driven architectures and distributed data systems in production you understand message ordering consumer behaviour replication and failure modes at the data layer.
• A track record of raising engineering standards: youve written the best practices doc run the design review or built the internal tool that made the right thing the easy thing.
• Production experience with container orchestration and modern infrastructure you understand how the platform your services run on affects their reliability and youre comfortable operating in that environment.
• Strong incident command and post-mortem skills you lead calmly under pressure and convert outages into durable engineering improvements.
• The ability to work in a flexible hybrid setup with 23 days a week in the office.
