Trading Systems Engineer
Job Description
Design, develop, and optimise low-latency, mission-critical trading systems. Own key trading stack components end-to-end — from architecture through to production operation. Collaborate closely with quants, traders, and engineers to deliver solutions that improve trading performance and resilience. Maintain and evolve trading infrastructure with a focus on performance, stability, observability, and operational excellence. Troubleshoot complex production issues across exchange connectivity, execution, and market data handling. Drive engineering standards through technical leadership, code reviews, and mentoring.
