Job Description

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.

Our Operational Technology (OpTech) projects are typically focused on novel communications and analytics, targeting a variety of platforms from bare-metal through to large-scale Android and Linux deployments. We're looking for full-stack developers who thrive on diverse requirements, capable of jumping from front-end design to embedded platform development throughout their working week.

While much of our exsiting work uses Python, with a strong understanding of languages such as C, C++, Kotlin, JavaScript and Rust, you'll fit right in. The OpTech team focuses on user-driven applications, often involving bespoke hardware solutions. While not required, the best candidates are those with strong fundamentals in Radio Frequency (RF) communications and a desire to learn more.

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

We are ideally looking for a candidate who holds an active Security Clearance to join our team, however, we will consider sponsoring new clearances for candidates that meet our technical requirements.
