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.
