• Ensure security risks and control effectiveness are clearly understood, challenged and transparent to the right decision-makers.
• Embed security into major technology change, cloud adoption, platform engineering, digital delivery and supplier-led transformation.
• Partner with technology and engineering leaders to make secure-by-design delivery practical, proportionate and commercially aligned.
• Oversee third-party and supply-chain security risk across key suppliers, affiliates and strategic partners.
• Coordinate internal and external assurance activity, including audits, independent assessments and regulatory engagement.
• Ensure findings, control gaps and regulatory commitments have clear ownership and are delivered to the required standard.
• Lead NewDay’s approach to AI security and governance, establishing practical controls that enable safe and responsible adoption.

What we’re looking for:

• You will be an established security leader who can combine strategic judgement with operational delivery.
• You will be comfortable leading broad, multidisciplinary teams while providing credible, concise advice to executives and Board-level stakeholders.
• You will bring significant experience leading a broad Information Security function within a regulated organisation, ideally financial services, consumer credit, cards, payments or FinTech.
