We are backed by British innovation and powered by world-class experts, like you. OMNIA is at the heart of the UK's bold Land Industrial Strategy.

About the Role

This is more than a job — it's a mission. You will be part of a high-impact, collaborative environment, where we expect everyone to live the values and standards of the British Army. Every person in our team plays a critical role in delivering OMNIA's vision; designing, delivering, and transforming collective training so the British Army is ready to fight and win.

You'll work in a matrix organisation and report operationally through OMNIA Training Support Branch and functionally through the Raytheon UK Engineering Management team, specifically the Systems Security Engineering Group. Ultimately, you'll work with the British Army, championing innovation, and helping shape the future of military collective training.

You will be required to design and support implementation and provide ongoing IA support of secure cloud solutions as well as on premises solutions as required. Managing the Omnia Security Team, you will be the Programme Secure by Design Subject Matter Expert.

This role will be based in the Warminster area with hybrid working arrangements.
