Solve critical challenges that protect secure spaces

As our Physical Technical Security Development Engineer, you’ll bring your deep-thinking technical mindset to resolve technical challenges as you work to create new Secure Spaces systems and capabilities. Working across Innovation & Development and with teams in UK NACE, you’ll design solutions, adapt, modify and enhance security systems to meet user requirements. Your ability to learn new technologies, analyse information and generate ideas would help you thrive in this role, as would your technical judgement and drive to keep things moving at pace.

You’ll test products thoroughly, understanding how they’ll work beyond the lab in real installation environments – and using what you learn to improve future designs. Delivering across multiple workstreams, you’ll know how to prioritise tasks, manage workload and even ask for support when needed. You’ll also work closely with colleagues, customers and suppliers to turn requirements into solutions, helping develop the products that meet the needs of the people who rely on them.

Bring your technical expertise to physical security

You’ll bring hands-on experience in secure working environments and physical technical security, accompanied by knowledge of systems such as access control and CCTV. Experience in designing, installing and supporting technical physical systems would be particularly useful, especially if you have a genuine interest in emerging physical security technologies and the curiosity to get up to speed with new disciplines quickly. A strong analytical thinker, you’ll be someone who enjoys getting to the heart of a technical problem and understanding what’s the detailed requirements and working out how to test a solution properly.

A people’s person through and through, you’ll practice strong stakeholder management as you balance the needs of internal customers with delivering project outcomes. You’ll be confident and adaptable – contributing ideas and finding solutions when things don’t go to plan. This is a role where your problem-solving skills and curiosity can make all the difference – shaping both the products we deliver today and the capabilities we develop for tomorrow.

Discover the support you need to grow your career further

Working with us you’ll help keep people, information, and assets safe around the world. It’s a role you can feel proud of; and we aim to make every part of your career just as rewarding. That’s why when you join us, expect to receive a competitive salary, good holiday entitlement and a Civil Service Pension. Along with this, you’ll also have access to training and other development opportunities to help grow your career with us. Our offices have an on-site gym, nursery, café, and restaurant, and we offer interest-free loans on season tickets and bikes to help you get there. It's a great set of benefits made to support all you do, and all you need.
