Senior Rust Engineer

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

• 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

• 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
