About the role

The CTO / Infrastructure Domain Architect is a Senior Architecture and people‑leadership role within Digital & Technology (D&T), accountable for shaping, governing and evolving the foundational technology capabilities that underpin all digital, data and business platforms at Haleon.

This role owns the architecture across core infrastructure and technology domains, ensuring they are secure by design, resilient by default, scalable at global scale and operable under stress, while supporting rapid innovation and delivery.

The role leads and develops a capability of Solution Architects across multiple technology domains and is accountable for architectural assurance, guidance and standards, ensuring consistency, confidence and safety across the D&T estate.

Working closely with the CTO/CIO leadership team, Cyber Security, Operations, Platform Owners and other Domain Architects, the role ensures Haleon’s architecture converges on fewer, strategic technology platforms, delivers end‑to‑end outcomes, and meets enterprise expectations for security, resilience, continuity and regulatory compliance.

The role brings a global technology perspective, including awareness of regionally distinct technology ecosystems such as China, to ensure architectures are globally scalable while accommodating legitimate local constraints.
