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.
