Senior Rust Engineer

About the company

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.

Your tasks

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

Requirements

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

What we offer

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
