Purpose of the role

The Generalist Principal Architect maintains a holistic, enterprise‑wide architectural view across business, application, information, integration, infrastructure, cloud and service domains. The role is technology‑agnostic and vendor‑neutral, providing independent, expert architectural leadership and assurance to ensure that technology change across the Group is coherent, scalable, secure and aligned to business strategy.

• Provide architecture governance and assurance for significant investments, initiatives and third‑party solutions.
• Ensure architectural decisions remain aligned to agreed target states throughout the delivery lifecycle.
• Act as a trusted advisor to senior business leaders, technology leaders and programme sponsors.
• Clearly articulate complex architectural concepts in business‑relevant language.
• Influence decision‑making through expertise, pragmatism and credibility rather than direct authority.
• Provide architectural leadership across internally delivered, platform‑based and supplier‑led solutions.
• Ensure vendor and partner solutions align with enterprise architecture, integration patterns and security standards.
• Promote open, interoperable and sustainable technology approaches.
• Maintain awareness of industry architecture trends and emerging technologies.
• Assess relevance pragmatically, balancing innovation with stability and value.
• Contribute to the ongoing maturity of Group architecture capability and practices.
