Principal Project Manager – National Timing Centre (NTC)

Our world‑leading Time & Frequency department is seeking a Principal Project Manager with proven expertise in strategic and operational oversight of security‑critical physical and technical delivery.

This is an exceptional opportunity to join the global authority in precision timing at a defining moment for UK digital infrastructure. 

Backed by a government investment of £180 million in the National Timing Centre (NTC) programme, we are developing a world-first resilient time distribution capability that will provide industry with a robust complement to satellite systems (such as GPS) – which are increasingly vulnerable to disruption from solar storms, jamming and spoofing. This will underpin essential services; including

• Telecommunications, 
• Online banking, 
• Emergency response, 
• Transport networks, and 
• Wider digital and data-driven operations.

Together, these services form the backbone of modern society - and your leadership will help ensure they remain secure, reliable and robust even if global navigation satellite systems fail. 

Key responsibilities:

• Strategic Workstream Leadership: Lead the end‑to‑end delivery of the Security Upgrade Workstream, owning the integrated workstream plan, critical path, resources and delivery health within the NTC programme.

• Physical–Technical Integration Management: Act as the primary interface between construction activity and complex security systems installation, ensuring sequencing, access, acceptance criteria and handovers are tightly coordinated.

•  Cyber & Systems Security Delivery: Oversee delivery of critical security systems—including SOC/SIEM integration, security architecture changes, testing and accreditation preparation - ensuring alignment with cyber governance standards.

• Governance, Reporting & Assurance Oversight: Maintain high‑quality, auditable documentation and produce clear, senior‑level reporting, contributing to programme‑level governance forums, change control processes and external assurance activities.

•  Senior Stakeholder & Contractor Management: Build trusted relationships across contractors, engineering teams, cyber specialists and programme leadership, providing authoritative communication, early escalation, and accountability for delivery outcomes.
