???? Senior Rust Engineer - Low-Level Systems | High-Performance | Hybrid London

I'm working with a leading financial technology organisation building ultra-low latency systems at scale, and we're looking for a Senior Rust Engineer with a strong grounding in low-level systems programming.

This is an opportunity to join a high-calibre team of engineers pushing the boundaries of performance and reliability in a demanding, mission-critical environment. The systems you'll help build operate in the microsecond range and demand deep OS, networking, and concurrency knowledge.

What You'll Be Working On:

Designing and developing low-latency, high-throughput microservices in Rust
Building and refining core components of a proprietary event-driven framework
Working closely with architects and infrastructure engineers to optimise performance across the stack
Developing systems with a focus on resilience, fault-tolerance, and scalability
Driving performance improvements with hardware-aware optimisations and kernel-bypass techniques

What We're Looking For:

Deep understanding of systems-level programming (Rust, C, C++)
Experience with manual memory management, concurrency, and multithreading
Familiarity with Linux internals, system calls, and networking (e.g., epoll, io_uring)
Bonus points for experience with:
- Kernel bypass (Solarflare, DPDK)
- Building custom allocators or working in no_std environments
- Prior work in trading, real-time systems, or performance-sensitive environments (previous finance experience not crucial)

Tech Stack Highlights:

Rust, Linux, GitHub, CI/CD (CircleCI), Docker, TCP/UDP, Playwright (some teams), OpenOnload, AWS

The Offer:

Base salary up to ~£140,000 depending on experience
Hybrid working: 2-3 days/week in a London office
Excellent benefits: pension, medical, 27+ days leave, bonus

Why This Role:

This is a career-defining opportunity to work on some of the most cutting-edge low-latency systems in the industry. You'll be part of a team that values technical depth, innovation, and clean engineering, all while working on systems where every microsecond counts.
