Senior Low Latency Rust Engineer

About the Role

The Senior Low Latency Rust Engineer will join a specialist team focused on building frameworks and performance tooling for a global electronic trading environment. This role involves hands-on coding primarily in Rust and modern Java, addressing complex performance challenges across multiple trading platforms.

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

Who You Are

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.
