## Description

Perfect role for a mid professional looking to grow their Defence & Government career in Southampton.

Defence programmes live or die on the systems holding them together, and right now a growing technology company in Southampton needs someone who can own that responsibility properly. This is a startup built around fast decision-making and real accountability, working on programmes that support national security outcomes. If you want your work to matter beyond a sprint board, this Systems Engineer (SC Cleared) role is worth a serious look.

Here's what you'll be doing:

Design, integrate and test complex systems across the full engineering lifecycle, from concept through to deployment

Work directly with government and defence stakeholders to translate operational requirements into workable technical solutions

Produce and maintain technical documentation, including system specifications, interface control documents and test evidence

Troubleshoot integration issues across hardware and software boundaries, often under time pressure

Support verification and validation activities, ensuring systems meet contractual and regulatory requirements

Collaborate with cross-functional teams including software, hardware and security specialists on a daily basis
