Senior Lead Software Engineer

I’m working with a technology-led investment firm in London that is looking for experienced Software Engineers to join a team building core engineering systems in Rust.

This is a hands-on role focused on performance, scale and reliability. You’ll be working on systems where concurrency, latency and efficiency genuinely matter, with plenty of ownership from design through to production.

What you’ll be working on:

• Building high-performance distributed systems in Rust
• Developing core infrastructure used by engineering teams across the business
• Solving problems around concurrency, multithreading, scalability and performance
• Designing new services and taking ownership through to production
• Improving the reliability and efficiency of existing systems
• Working in Linux environments and getting into how the software behaves under real production load

What makes the opportunity interesting:

• You’ll be working on technically difficult systems where performance and scale are core to the job
• There’s real ownership, rather than just picking up small pieces of a much larger platform
• You’ll be working with Rust commercially and using it on genuinely important production systems
• Strong backgrounds in distributed systems, systems engineering, concurrency or performance-focused software would all be relevant
• It gives you the chance to stay close to the code while working on complex engineering problems with strong engineers around you
• Good algorithms, data structures and low-level problem solving will actually matter here rather than just being interview theory

This would suit someone who enjoys building fast, reliable systems and wants to work somewhere the engineering problems are genuinely difficult.
