Job description

Most engineering roles ask you to build one system well. This one asks a harder question: how do a dozen systems, built by different people at different times, behave as one? A multinational defence organisation needs a systems engineer for exactly that problem, in the air command and control domain.

You would work across the full lifecycle — from requirements and traceability, through technical baselines and interface management, to integration planning and the verification strategy that proves it all holds together. It is a role for someone who is comfortable with structured engineering practice and equally comfortable asking whether the end user can actually work with the result.

What you would be doing

• System-of-systems engineering and lifecycle management.
• Requirements engineering and traceability, using structured tooling such as DOORS or equivalent.
• Technical baseline and interface management.
• Integration planning and development of the verification strategy.
• Applying operational domain knowledge, particularly air command and control, federated mission operations and how the wider organisation is put together.
• Human factors, usability analysis and user journey assessment — making sure the capability is usable, not merely compliant.

What we are looking for

• A BSc from a recognised university in a technical subject with substantial IT content, plus three years of relevant experience — or, in place of the degree, at least five years of extensive and progressive experience in this kind of work.
• Real system-of-systems and requirements engineering practice, with structured tooling.
• Experience of technical baselines, interfaces and integration verification.
• Desirable: prior work in an international environment of both military and civilian staff, and knowledge of how such an organisation is structured.

The work is full time on site in The Hague, the Netherlands, from early September to the end of December 2026.
