Infrastructure Design Project Manager – Defence Estate (SC Cleared)

An SC cleared Engineering Infrastructure Project Manager is required in Portsmouth to support a major defence client on a high‑profile, complex estate development programme within a secure naval environment. This is a contract role, operating on a hybrid basis with a minimum of two days per week on site.
This role sits firmly at the planning and design stage of a substantial long‑term programme. You will be supporting the early development of a site‑wide masterplan and RIBA Stage 2 design for a circa £900m accommodation programme. This is not a construction delivery role — the focus is on infrastructure design management, stakeholder coordination and client‑side leadership.
You will work within a multi‑disciplinary project team, managing internal client resources and helping shape the technical and strategic direction of the programme at a formative stage, where decisions genuinely matter.

Key responsibilities include:

• Delivering client‑side infrastructure project management services within a secure defence estate
• Managing and coordinating infrastructure design activities to support a site‑wide master plan
• Supporting development through RIBA Stage 2 design, ensuring scope, programme and outputs remain aligned
• Leading and coordinating internal project team resources and stakeholders
• Applying NEC4 principles where appropriate (experience preferred, training can be provided)
• Working collaboratively with technical, commercial and assurance functions

To be suitable for this role, you will ideally bring:

• Proven infrastructure design management experience (essential)
• Around 4–5 years’ post‑graduate experience in a relevant project environment
• A degree‑level qualification and a recognised professional project management qualification
  (APM PMQ, CPP or similar practitioner‑level certification considered)
• Experience working on complex, regulated or secure sites
• Active SC Security Clearance (essential)

Contract details:

• Initial 6‑month contract
• Hybrid working: minimum 2 days per week on site in Portsmouth (up to 3 during peak periods)

This opportunity would suit an Infrastructure Project Manager who enjoys early‑stage programme shaping, client‑side leadership and working on nationally significant defence infrastructure.
