Job description

Do you want to be at the heart of some of the biggest and most ambitious programmes undertaken to keep our country safe?

We are proud of the impact we have with our Defence & Security clients, the strength of our relationships, and the variety of skills and expertise we bring to help them achieve their mission. Our engineers build the digital foundations behind some of the most complex systems in government – from critical infrastructure to advanced data platforms.

We don’t just test code – we test products that matter. As an Automation Engineer here, you’ll apply engineering discipline to drive quality – building automation frameworks that scale, crafting solutions that find defects fast to accelerate delivery, and helping our clients build confidence in what they deploy.

We’re growing rapidly across our Defence portfolio, with opportunities for candidates who hold or are eligible for Security Check (SC) clearance, as well as those who already hold Developed Vetting (DV) clearance. If you want to design, build and test solutions that make a national impact, we’d love to meet you. See the Security Clearance section below for details of each route.
