We are seeking an experienced Product Owner to support a highly secure military programme. This role sits at the sharp end of defence IT, owning infrastructure outcomes across design, implementation, and ongoing technical assurance for mission-critical systems.

You will act as the technical authority for infrastructure decisions, working closely with military stakeholders, architects, and delivery teams to ensure platforms are secure, resilient, interoperable, and fit for operational use.

If you've never worked in a locked-down environment with real consequences, this role will feel uncomfortable. If you have - it'll feel like home.

• Engage confidently with senior MOD and military stakeholders

• Produce and review technical documentation suitable for secure and audited environments

Essential Experience

• Proven experience delivering defence or military IT infrastructure

• Strong background operating in highly secure / classified environments

• Previous experience in a Product Owner, Technical Lead, or Senior Infrastructure role

• Deep experience with server infrastructure (Windows Server essential; Linux desirable)

• Strong expertise in Microsoft Exchange (secure configurations, migrations, hybrid models where applicable)

• Demonstrable delivery of interoperable infrastructure across complex estates

• Experience working with restricted networks, air-gapped environments, or cross-domain solutions
