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
This is an exceptional opportunity to apply your Rust expertise at the cutting edge of network technology. To discuss in confidence — send your CV or get in touch today.
