We’re looking for a Lead Security Architect to join our Insurance, Money & Services team.

This is a leadership role accountable for shaping and governing our enterprise security architecture strategy. You will define modern security architecture principles, provide expert design assurance, and influence technology decisions across major programmes. Acting as a trusted advisor to senior leadership, you’ll embed secure‑by‑design thinking, champion Zero Trust principles, and ensure that our solutions protect customers, colleagues, and critical services.

What you’ll be doing
• Define and maintain the enterprise security architecture roadmap, ensuring alignment to business strategy and regulatory requirements.
• Lead security assurance activities — design reviews, threat modelling, and control validation — ensuring solutions meet our security standards and risk appetite.
• Set security architecture principles and standards, driving adoption of industry frameworks such as NIST, ISO 27001, and Zero Trust.
• Influence senior stakeholders, shaping technology strategy, investment decisions, and architectural direction across the organisation.
• Develop and lead the security architecture function, coaching architects and building capability across teams.
• Provide authoritative guidance on remediation of design gaps and non compliance, partnering with delivery teams to embed security early and prevent downstream issues.

We need you to have
• Security architecture expertise: Proven experience leading enterprise level security architecture, security assurance (design review, threat modelling, control validation), and governance across complex environments.
• Leadership & communication: Ability to influence senior leaders, guide strategic decisions, and develop technical talent.
• Technical & regulatory knowledge: Strong understanding of security frameworks (NIST, ISO 27001), secure design principles, and emerging technologies, alongside awareness of regulatory and operational compliance requirements.
• Professional certifications (desirable):
• CISSP, CISM, SABSA, CCSP, TOGAF, or cloud architecture certifications (AWS/Azure).
We don’t expect you to tick every box, and if you feel you hit most of the brief, it’s worth exploring to further develop your career here with us.

What’s in it for you
• Prepare for your retirement with our colleague pension scheme.
• Private Medical Insurance (WL2+) and virtual GP Service you and your family 365 days a year.
• Critical Illness Insurance.
• Performance related annual bonus.
• Indulge in a generous holiday allowance with a minimum of 7.2 weeks, with the opportunity to buy more.
• Embrace the benefits of our Colleague Clubcard, enjoy a 10% discount that increase to 15% every payday. As an added perk, we’ll give you a second card to share with someone else.
• Benefit from our family-oriented initiatives, encompassing enhanced maternity leave pay, a shared parental leave policy, and a generous 8-week paid paternity leave.
• A place to get on - take advantage of our ongoing learning opportunities and award-winning training, to help you achieve the job and career you want.
• Take part in our Buy as you Earn and Save as your Earn share schemes.
