Senior Low Latency Rust Engineer

Senior Low Latency Rust Engineer – Electronic Trading London | Hybrid – max 3 days per week in office We are assisting with the hire of an experienced low-latency engineer to join a specialist team building frameworks, libraries and performance tooling used across a large global electronic trading environment. This is not a traditional BAU development role attached to one desk or application. The team works across multiple trading platforms, solving complex performance problems and helping define how latency-sensitive systems should be engineered. Approximately 90% of the role is hands-on coding, with a major focus on Rust alongside modern Java. What you'll work on Low-latency Rust and Java frameworks Event-sourced systems operating in the 10–100 microsecond range Market-data replay, backtesting and simulation tooling High-performance market-data processing Linux, kernel and systems-level performance optimisation TCP/IP networking and kernel-bypass technologies Performance profiling, benchmarking and latency reduction Frameworks and tooling used across 100+ technology teams What we're looking for You'll ideally come from a background in algorithmic trading, electronic trading, market data or another genuinely latency-sensitive environment. Financial Services background is not crucial. Relevant experience could include: Rust, modern Java or C++ Low-latency / high-throughput systems Algorithmic or electronic trading Market-data technologies Linux internals and kernel behaviour TCP/IP networking Solarflare / OpenOnload or similar kernel-bypass technologies KDB or other time-series databases Performance tuning and optimisation You do not need to match every technology listed. The key requirement is genuine depth in high-performance systems engineering and an ability to understand latency across the full stack. Why consider it? The standout here is the combination of: Rust + microsecond-level performance engineering + large-scale production electronic trading. You'll remain deeply hands-on while working on engineering problems that sit underneath multiple trading platforms, rather than maintaining a single application.
