About The Role
PwC’s Cyber, Data & Technology Resilience practice works at the intersection of national security, critical infrastructure protection, and enterprise risk. We advise governments, Defence organisations, and their supply chains on complex cyber security challenges that require specialist expertise and experience. Defence is a key growth priority for PwC UK. As demand continues to expand, we are looking for experienced leaders to help shape and deliver cyber security solutions across large-scale Defence programmes, strengthening resilience across mission-critical systems and sensitive environments.
As a Senior Manager, you will lead security architecture and assurance workstreams within major Defence engagements. You will design how security operates across complex environments—from classified cloud platforms to operational military systems—ensuring alignment with MOD security governance and enabling successful programme delivery. This is a highly visible, client-facing role combining technical leadership, delivery ownership, and stakeholder engagement.

- Lead security architecture design across Defence programmes, defining controls, patterns, and governance for systems operating at OFFICIAL, SECRET and above
- Own and drive Secure by Design assurance activities throughout the programme lifecycle
- Lead accreditation and assurance processes, including security cases, risk assessments, and MOD-aligned documentation
- Advise senior programme stakeholders on security risk and trade-offs, translating technical issues into business decisions
- Manage relationships with MOD security authorities, CISOs, and accreditors
- Lead delivery teams across security workstreams within large transformation programmes
- Contribute to bids and proposals, bringing technical credibility and real-world delivery insight
- Mentor and develop Managers and Senior Associates within the team
This Role Is For You If
- You have experience in security architecture within Defence or Central Government environments, including systems operating at OFFICIAL-SENSITIVE or above
- You understand MOD security governance, including Secure by Design, JSP 440, JSP 604, and accreditation processes
- You bring experience across Defence environments such as classified cloud, cross-domain solutions, identity, and network segmentation
- You have delivered within large-scale programmes, with understanding of enterprise architecture, programme governance, and multi-vendor environments
- You demonstrate strong leadership, including stakeholder engagement, team management, and high-quality security documentation, supported by relevant certifications (e.g. CISSP, CCP, TOGAF or equivalent)
