• Lead and mentor small technical teams working in client‑facing environments.
• Engage with senior stakeholders to influence strategy and solution outcomes.
• Support bids, proposals, and business cases for new Defence programmes.

What You Bring

• Proven delivery of secure, complex digital and IT systems at enterprise scale.
• Experience across cloud, cybersecurity, integration, and deployable technologies.

• Familiarity with Defence frameworks (desirable).
• Excellent communication and technical writing skills for governance boards and bids.
• Comfortable leading teams and operating across multi‑supplier environments.
