Senior Rust Engineer

Rust Software Engineer | Up to £130,000 | Remote
About the Role
My client, a pioneering UK technology firm redefining global communication networks. They are building solutions that operate where standard systems fail — powering resilient, far-reaching connectivity across critical environments.
They are seeking a Rust Engineer to join their core R&D team and lead development of the next generation of their tech stack and platform. You will write high-performance, production-grade Rust that directly shapes how networks run worldwide.
This isn’t just coding — you’ll build systems that solve genuinely complex problems for customers and partners across the globe.
What You’ll Be Building
* Develop and maintain high-performance DTN products, platforms, and APIs — predominantly in Rust — using gRPC and Protocol Buffers
* Architect and scale distributed, cloud-native systems running on Kubernetes
* Own code from design through to production: implement, debug, test, and optimise
* Modernise and evolve existing capabilities with cutting-edge approaches
* Collaborate across full-stack teams to pair robust backend logic with seamless user experiences
* Translate technical and commercial needs into elegant, maintainable Rust solutions
* Create documentation, tutorials, and sample code to empower developers and customers using The Relay Network
* Support customer onboarding — guiding integration and ensuring systems perform at scale
* Benchmark and refine performance for large-scale global deployments
What You Bring — Essentials
* Strong professional experience writing production Rust — you understand idiomatic design, concurrency, and performance characteristics
* Degree in Computer Science, Software Engineering, or related technical discipline
* Proven ability to communicate complex technical concepts clearly to engineers, customers, and stakeholders alike
* Curiosity that goes deeper than code: you want to understand the business and the ecosystem your systems serve
* Experience working directly with end-users — diagnosing issues, proposing solutions, and building trust
* A genuine passion for championing great technology
Highly Desirable
* Hands-on experience designing distributed microservice or event-driven architectures
* Track record of well-tested, scalable Rust code — leveraging concurrency patterns, unit/integration testing, containerisation, and CNCF ecosystem tools
* Cloud platform experience — GCP, AWS, or equivalent
Why This Role Stands Out
* Rust-first stack — you’ll work with a modern, high-performance language at the core of everything they build
* Impactful technology — your code will underpin real-world critical communications infrastructure
* Deep technical autonomy — small expert team, minimal bureaucracy, strong engineering culture
* Global reach — your systems will be deployed internationally by leading organisations
