Software Acquisition Engineer in Warminster

At Defence Equipment & Support (DE&S), we supply and maintain vital equipment and services for the Royal Navy, British Army and Royal Air Force. Together, we deliver a vast range of essential defence programmes, and strive for what's next. Because it helps keep our military at the top of their game and our nation safe – for today, and tomorrow.

DE&S has recently been integrated into the National Armaments Director (NAD) Group. The NAD Group brings together key Ministry of Defence (MOD) organisations to unite expertise across science, technology, procurement, infrastructure, and support to provide integrated capabilities faster and more efficiently for our armed forces and our allies. This is an exciting new opportunity to enable better ways of working and empower greater collaboration across Defence.

We offer 25+ days’ holiday, flexible and hybrid working, enhanced parental leave schemes, shopping discounts, and an exceptional employer pension contribution of 28.97%, to help make work for you.

This role requires you to have lived in the UK for the last 5 years and obtain Security Check (SC) security clearance. Clearance must be obtained without any caveats that prevent you from carrying out the role you’ve been recruited for. If it isn’t obtained, or is obtained but with caveats that prevent you from carrying out the role, any conditional offer made to you will be withdrawn. Obtaining SC security clearance can be a lengthy process, and we reserve the right to withdraw any conditional offer made if the necessary security clearance isn’t obtained within 12 months.

The Joint Asset Management and Engineering Solutions (JAMES) Lead Engineer is the senior technical authority responsible for assuring the safety, security, integrity, availability, and technical sustainability of the JAMES capability, a mission-critical Defence information system supporting over 40,000 users and millions of equipment records across Defence.

The role provides authoritative leadership across systems engineering, safety assurance, cyber security, technical governance, and service sustainment, ensuring JAMES remains legally operable, secure, compliant, and fit to support Defence operations. It also enables the transition to the replacement Defence Equipment Engineering Asset Management Systems (DEEAMS) capability and the controlled retirement of JAMES through 2029.

You will be required to possess strong technical expertise in software assurance, systems engineering, information systems engineering, safety and cyber security oversight, technical assurance, integrated risk management, obsolescence management, and transition/decommissioning planning. You must also be capable of leading the remediation of significant cyber vulnerabilities, maintaining Authority to Operate (ATO), assuring engineering compliance, managing technical risks, and providing strategic technical direction across a complex safety-critical Defence environment.

This role requires exceptional technical leadership, systems thinking, engineering judgement, analytical problem-solving, risk-based decision-making, stakeholder engagement, influencing skills, and the ability to provide clear technical advice to senior military, commercial, and Defence stakeholders. You must demonstrate calm and decisive leadership under pressure, maintain a strong assurance mindset, and balance safety, security, operational effectiveness, technical risk, and business priorities.

Due to the safety-critical nature of the position and the need for close collaboration with military users, Lockheed Martin, Business Modernisation for Support (BMfS), and other Defence stakeholders, you will be required to be based in Warminster and spend a minimum of 60% of your time on-site, providing visible leadership and direct oversight of engineering assurance, service delivery, cyber remediation, and DEEAMS transition activities.

It would be advantageous for you to have previous JAMES experience and understanding of Defence equipment management, engineering assurance, and the operational environment in which the capability is used but is not essential and can be taught whilst in post.
