About The Role :

Were looking for a Senior Trading System Automation Test Tool Developer with a strong background in Java and Python to design and build next-generation testing and automation tools for our institutional trading platform.

This role is central to enabling automated validation of order lifecycles, venue connectivity, and low-latency behavior across our trading stack.

Youll work closely with strategy developers, support engineers, and QA to deliver a robust automation framework that improves developer velocity, system reliability, and test coverage for trading workflows.

Ideal candidates will have experience in OMS/EMS systems, deep knowledge of trading protocols like FIX, and a passion for building tools that bridge development and production operations.

What Youll Do :

- Design and implement frameworks for automated testing of order entry, modification, routing, and risk logic.

- Build tools in Java / Python or Rust to simulate and validate end-to-end trading workflows across low-touch and high-touch systems.

- 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 Were 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.
