UK Security Clearance eligibility required

An opportunity has opened for an experienced Senior Rust Developer to join a growing engineering team working on next-generation, cutting-edge national defence technologies. This is a genuinely technical role for somebody with strong commercial Rust experience who is comfortable working across secure systems, networking, distributed architectures and cryptography. Youll be involved throughout the engineering lifecycle designing and developing secure, high-performance software, solving complex technical problems and contributing to architecture and security decisions across highly sensitive systems.

What youll be doing

• Designing and developing high-performance software using Rust
• Building distributed and networked systems
• Working with Zenoh / Eclipse Zenoh, including publish/subscribe and peer-to-peer communications
• Developing secure communications using TLS 1.2/1.3, mTLS, PKI and X.509 certificates
• Working with certificate lifecycle management, trust chains and secure key management
• Applying cryptographic principles including encryption, hashing, digital signatures and key exchange
• Developing resilient network services using TCP/IP
• Investigating complex software, networking, security and performance issues
• Identifying and reducing technical, architectural and cyber-security risks
• Maintaining high standards across secure coding, automated testing and code review
• Providing technical guidance across multidisciplinary engineering teams

• Software architecture, debugging and complex problem solving
• Automated testing, Git and CI/CD
• Experience with technologies such as rustls, OpenSSL, RustCrypto, Tokio, HSMs, TPMs, Zero Trust architectures, embedded/edge systems or other high-assurance software environments would be particularly useful.
• Defence / Security
• Previous experience within Defence, National Security, Government or another security-sensitive environment would be advantageous, particularly where youve worked on secure communications or high-assurance software.
• You must be able to obtain and maintain the appropriate level of UK National Security Vetting for the position. Existing clearance would obviously be beneficial but isnt necessarily essential.

Why consider it?

This isnt a standard commercial Rust role. Youll be working on complex, technically demanding systems where performance, resilience and security genuinely matter, within a business developing cutting-edge national defence technology.
