Senior Rust Engineer
Licensed sponsor London Full-time Posted 18 hours ago
We are looking for a Rust Specialist to join a high-caliber, nimble engineering team rewriting the core components of a global equities execution platform.
Responsibilities
- Rewrite Core Execution Systems: Architect and build core equities execution platform components using allocation-free, close-to-the-metal Rust.
- Optimize Hot-Path Performance: Eliminate tail latency and jitter by leveraging mechanical sympathy, NUMA awareness, and kernel bypass techniques.
- Build Deterministic Replay & Testing: Implement rigorous property-based tests, simulation tools, and deterministic replay to guarantee absolute system reliability.
- Leverage AI-Assisted Workflows: Integrate modern AI tooling (e.g., Claude Code) to accelerate feature development without compromising code quality.
- Drive Technical Benchmarking: Measure latency distributions, analyze histograms, and clearly articulate performance and architectural trade-offs.
Requirements
- Hot-Path Architecture & Design: Architect, build, and optimize high-throughput, low-jitter Rust systems on the critical execution path.
- Low-Level Performance Tuning: Write zero-allocation, contention-aware code while managing CPU caches, memory layouts, and hardware affinity.
- Network & OS Optimization: Leverage kernel bypass, busy-polling I/O, and NUMA-aware memory management to strip latency out of the network path.
- Deterministic Testing & Reliability: Implement property-based testing, deterministic replay, and simulation environments to ensure flawless system reliability.
- AI-Assisted Delivery: Integrate modern AI engineering tooling (e.g., Claude Code) to accelerate development workflows without compromising quality.
