Help shape the future of secure enterprise architecture. Join a major UK Utilities organisation leading a £100M transformation of its digital and operational technology estate. From ServiceNow implementation and back-office system upgrades to cloud integration and modernisation of on-premise data centres, this is a rare opportunity to architect security across one of the UK's most critical infrastructure environments.
As a Security Architect, you'll embed secure-by-design principles across IT and OT systems, working alongside Solution Architects and a dedicated Cybersecurity team. You'll guide technical decisions that ensure risk, compliance, and innovation are aligned from day one.
What You’ll Do
- Define and deliver enterprise-wide security architecture across hybrid cloud, on-prem, and OT environments.
- Collaborate with technical and non-technical stakeholders to embed security into solutions from design through to delivery.
- Develop reusable security patterns, architecture principles, and frameworks.
- Drive security architecture across digital programmes such as ITSM (ServiceNow) and back-office modernisation.
- Conduct threat modelling, risk analysis, and define security requirements for systems including remote access (VPNs) and secure OT-to-IT data exchange.
- Ensure compliance with industry standards such as ISO27001, NIS Directive, and NCSC's Cyber Assessment Framework (CAF).
- Support long-term architectural planning, contributing to multi-year roadmaps and aligning solutions with regulatory and business strategy.
What You’ll Bring
- 3+ years of experience as a Security Architect, ideally in enterprise or regulated environments.
- Deep understanding of IT/OT architecture, including air-gapped systems and the Purdue model.
- Experience supporting large-scale transformation programmes with cloud, infrastructure, and legacy system exposure.
- Familiarity with industry standards and secure system development life cycles.
- Strong stakeholder engagement skills, able to align security decisions with business goals.
Desirable
- Hands-on experience with ServiceNow or similar ITSM platforms.
- Familiarity with utilities, energy, or critical infrastructure sectors.
- Prior experience working with or in a Distribution Network Operator (DNO).
- OT security experience is highly beneficial, but we also welcome strong cloud/infrastructure candidates looking to grow in this space.
What You’ll Get
- Base Salary: Up to £70,000
- 12% Company Pension + Annual Bonus (up to 15%)
- Car Allowance (~£3K)
- 25 Days Annual Leave + Bank Holidays
- Long-term career progression in a high-impact national infrastructure programme
Your Focus: Security Architecture. You’ll lead on design and governance, while working closely with a separate Cybersecurity team handling operational response and tooling. Apply now to play a strategic role in securing one of the UK's most ambitious digital transformations.
