Infrastructure Design Project Manager – Defence Estate; SC Cleared

Overview

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.

• Applying NEC4 principles where appropriate (experience preferred, training can be provided)
• Working collaboratively with technical, commercial and assurance functions

• Around 4–5 years’ post‑graduate experience in a relevant project environment

• Active SC Security Clearance (essential)
