Rust Software Engineer | Up to £145,000 | 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.
