Rust Engineer

Staff Rust Engineer

Central London (hybrid, 2–3 days per week in the office)

£80,000–£110,000 DOE

Permanent, full time

Build clever software.

We have partnered with an ambitious, well-funded SaaS technology startup entering an exciting phase of growth who are looking for a Staff Rust Engineer to help shape the technical direction of their platform, working on complex engineering challenges where performance, scalability and analytical thinking are critical.

This is more than a senior development role. You will be a technical leader, influencing architecture, mentoring engineers and working alongside product and leadership teams to build software that makes a real impact, so you will need to enjoy solving difficult problems, thinking deeply about system design and writing high-quality Rust code.

You will be

• Designing and building high-performance backend services using Rust.
• Leading technical architecture and engineering best practice.
• Solving complex technical and analytical challenges.
• Mentoring and supporting other engineers through technical leadership and code reviews.
• Improving the performance, scalability and resilience of the platform.
• Driving engineering excellence across architecture, tooling and development processes.

You will have

• Strong commercial experience developing software in Rust.
• Experience operating at Senior, Principal, Lead or Staff Engineer level.
• A track record of designing scalable, distributed systems.
• Excellent problem-solving skills and an analytical approach to engineering challenges.
• Experience making architectural decisions and influencing technical direction.
• Strong communication skills and the ability to work across technical and non-technical teams.

The team are particularly interested in engineers who naturally enjoy breaking down complex problems and finding elegant, scalable solutions, so backgrounds involving complex analytical thinking are of particular interest, such as

• Mathematical modelling
• Optimisation algorithms
• Simulation or computational modelling
• Scientific computing
• Quantitative software engineering
• Data-intensive or high-performance systems
• AI or Machine Learning infrastructure
• Financial modelling
• Operations research
• Complex algorithms and data structures

If you are passionate about Rust, enjoy solving complex technical problems and want to help build something meaningful in a fast-moving startup environment, this could be a fantastic opportunity for you.
