Senior Rust Low Latency Engineer

Senior Rust Low-Latency Engineer | Electronic FX / HFT | Fully Remote | £600–£700 per day | Outside IR35

Albert Bow is working with a well-backed, early-stage FX business building an institutional-grade algorithmic trading capability. The core platform is already in place, with production infrastructure running on dedicated co-located hardware. They are now looking for a senior Rust engineer to help stabilise, optimise and extend the existing system while building out the next generation of execution and order management infrastructure.

This is a highly hands-on position within a small engineering and quantitative team, suited to someone comfortable moving between market data, execution, networking, performance optimisation and production troubleshooting.

Responsibilities

• Develop and optimise latency-sensitive FX trading infrastructure primarily in Rust.
• Work across market data, execution, connectivity and order management.
• Build connectivity to FX venues, ECNs, liquidity providers and market data sources.
• Work with FIX, ITCH and other native or binary trading protocols.
• Profile production systems and remove bottlenecks across CPU, memory, networking and application code.
• Diagnose latency, reliability and correctness issues within an existing production codebase.
• Improve observability, failure handling and overall production readiness.
• Work directly with quantitative researchers to turn execution requirements into robust production systems.

Requirements

• Strong production-level Rust experience with the ability to become productive in an existing codebase quickly.
• Significant experience building low-latency, high-performance or HFT systems.
• Experience with electronic trading infrastructure such as market data, feed handlers, execution systems, OMS or venue connectivity.
• Strong Linux, networking, concurrency and systems-level debugging knowledge.
• Deep understanding of CPU and memory behaviour, profiling, benchmarking and performance optimisation.
• Experience working with real-time market data and execution workflows.
• Comfortable taking ownership of difficult problems across multiple areas of the stack.

Nice to Have

• Direct electronic FX or HFT FX experience.
• Knowledge of FX ECNs, liquidity providers, last-look mechanics and execution behaviour.
• Experience with venues such as EBS, LSEG, Cboe FX, Currenex or LMAX.
• Kernel bypass technologies such as DPDK, Solarflare or OpenOnload.
• Lock-free programming and advanced multithreading.
• Dedicated bare-metal or co-located trading infrastructure.
• C++ or Java experience alongside Rust.
• FPGA exposure.

What’s on Offer

• £600–£700 per day, or local equivalent.
• Outside IR35 for UK engagements.
• Initial 6-month contract with strong potential for extension.
• Fully remote, with candidates considered globally.
• Must be able to work broadly around UK core hours.
• Direct exposure to genuinely latency-sensitive FX infrastructure running on dedicated hardware.
• Small team with significant ownership and close access to senior engineering leadership and quantitative research.
