We have an opportunity for a Principal Engineer working with a particular focus on our defence and security clients. You’ll join a team of talented engineers and scientists designing, building, and testing intelligent, human-centric systems.
As one of the senior technical voices in the team, you’ll be architecting the technical approach on our projects, setting the technical bar for others, and helping shape the work we deliver. As well as hands-on research and engineering, you’ll spend time with clients, using your expertise to win new projects as well as deliver them.
Much of our defence and security work requires security clearance, so we ask for it up front. You won’t work exclusively in that sector, but a genuine interest in it matters to us.
We offer a flexible approach to hybrid working, although some of the projects you will be working on will require full-time working in the office.
We are looking for an experienced technical lead, with the scientific and engineering breadth to guide the human-centric component of multidisciplinary work and the ability to work with our commercial teams to help create and win new work.
Because of where this role sits, holding (or being able to obtain) UK security clearance is essential. You must be eligible to obtain Security Check (SC) level security clearance (https://www.gov.uk/guidance/united-kingdom-security-vetting-applicant). You must be able to work in the UK without restrictions in accordance with UK National Law and be prepared to successfully undertake an appropriate level of UK National Security Vetting according to UK Government criteria.
While not essential requirements, we would also be very interested if you have experience with any of the following:
