Develop self-service systems for trade simulation, venue behavior replay, and FIX protocol testing. Work closely with front-office support and engineers to automate health checks, venue cert scripts, and regression test pipelines. Integrate test harnesses with CI/CD pipelines for pre-deployment safety checks and latency monitoring. Ensure systems are observable and fault-tolerant, with tooling that supports debugging and issue reproduction. Support and extend test capabilities for WebSocket, REST, and FIX APIs used across exchanges and internal strategies.

What We’re Looking For

5+ years of experience building and testing distributed trading systems. Strong proficiency in Java (11+) and Python for building automation frameworks, trading system test harnesses, and performance tuning tools; experience with Rust is a plus. Experience with OMS/EMS platforms, ideally with exposure to order lifecycle, FIX messaging, and venue connectivity. Familiarity with test automation frameworks and continuous integration practices. Working knowledge of market structure, electronic trading workflows, and latency analysis. Proficiency with scripting (e.g., Python, Shell) to support testing and monitoring automation. Familiarity with high-performance messaging (e.g., Aeron, Chronicle, Kafka) and network debugging.

Bonus Points

Experience building tools for exchange certification, regression harnesses, or FIX simulators. Exposure to market-making systems, risk engines, or smart order routers. Prior work in crypto or electronic trading in traditional finance.
