High-Integrity Software Engineer

Our Capability Development team develops bespoke software for our clients in the Cyber Security domain. We may be building assured software that prioritises engineering rigour and reliability, rapid cyber solutions that stitch together tooling for high‑impact results, or blended operational systems that address real-world challenges in the field.

Common to all is commitment to technically led decisions, to meaningful technical challenge, and to engaging career paths where your work makes it off the shelf and into the hands of our customers. All of our roles demand strong technical expertise, meticulous attention to detail, and a commitment to delivering robust, dependable solutions that our clients can rely on when it matters most.

Across our projects, we work on a variety of platforms; typically iOS, Android, and Linux, with opportunities on embedded systems and other specialised platforms. Our bread and butter is C, C++, and Java, but we're comfortable in Python, Rust, and JavaScript.

We emphasise having a comprehensive understanding of the programming languages, platforms, and tooling we rely on. That deep technical knowledge has helped us earn a reputation for writing novel, robust, and maintainable solutions to our client's challenging and fascinating problems and we regularly see the direct impact of our work.

We're led by engineers and empowered to optimise our (lightweight!) development processes with the knowledge gained from each project.

We are looking for a candidate who holds an active Developed Vetting security clearance to join our team.
