Senior Rust Engineer (High-Frequency Trading)
Contract Length: 6 months (with potential extension)
Location: London (4 days per week onsite)
Day Rate: Up to £800 (Outside IR35)
We're looking for an experienced Senior Rust Engineer to take ownership of a greenfield high-frequency trading (HFT) platform, leading the development of the execution layer and market-making system. You'll step into a technical leadership role, driving architecture, improving performance, and ensuring the system is built to world-class standards. If you've built ultra-low-latency trading systems before and want to take full responsibility for a new Rust-based platform, this is an opportunity to shape a high-impact project from the ground up.
Key Experience Needed
- Extensive experience designing and developing high-frequency trading systems
- Strong experience working on Rust with a track record of building low-latency, high-throughput production systems
- Proven ability to lead the build of execution engines, market-making platforms, or similar low-latency trading infrastructure
- Strong background in system architecture, performance optimisation, and fault-tolerant distributed systems
- Experience replacing or migrating systems from languages such as Python into Rust
- Comfortable taking full ownership of a greenfield project with minimal guidance (Self Starter)
- Strong collaboration attitude across engineering teams
- Flexible with working remotely but still keen to head into the office when necessary
Key Responsibilities
- Own and drive the development of the execution layer and market-making components of the HFT platform
- Architect, design, and implement ultra-low-latency Rust systems from first principles
- Improve, refactor, and optimise the existing codebase to meet best-in-class performance standards
- Replace or modernise existing Python-based components where appropriate
- Collaborate with cross-functional teams to deliver an integrated, production-ready trading system
- Lead technical decision-making, architecture discussions, and coding standards for Rust development
- Ensure seamless integration with UI and supporting engineering teams
- Contribute to rapid iteration, debugging, and refinement through close in-office collaboration
