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.
