Senior Enterprise Architect

Role Overview

As a Senior Enterprise Architect at Centrica, you will shape and evolve the company’s enterprise architecture across a complex, fast-moving technology landscape. You will define platform roadmaps, reference architectures, and architectural guardrails that enable delivery teams to accelerate while staying aligned to broader business priorities and technology strategy. Working across Retail, Optimisation, Corporate Systems, and Infrastructure pillars, you will provide enterprise-level leadership on platform design, application portfolio rationalisation, governance, and emerging technologies such as AI and cloud services.

• Develop and maintain enterprise platform roadmaps for assigned domains, setting clear sequencing, dependencies, and decision points to align technology direction with business priorities and the wider Centrica Technology Strategy.
• Own and evolve assigned platforms within the enterprise reference architecture, maintaining platform information, lifecycle status, capability mapping, and architectural guardrails to support effective design and governance across the estate.
• Provide enterprise-level architectural leadership on technology choices, emerging trends, AI adoption, and platform strategy, helping teams make informed decisions that balance cost, risk, resilience, and long-term sustainability.
• Support application portfolio rationalisation and lifecycle management, reducing duplication, complexity, and technical debt while improving visibility of legacy platforms, decommission dependencies, and transition risks.
• Work closely with pillar architecture teams, solution architects, engineering functions, and business stakeholders to shape architecture early, build alignment across roadmaps, and ensure decisions are supported by clear evidence and trusted relationships.
• Contribute to architectural governance through enterprise forums, significance assessments, and standards development, while coaching architects across the wider community and raising overall architectural maturity across the organisation.

• Strong experience in enterprise architecture with the ability to define and embed reference architectures, platform guardrails, and technology roadmaps across a large and complex organisation.
• Demonstrated knowledge of application portfolio management, including lifecycle management, rationalisation, capability mapping, and the use of architectural tooling such as LeanIX, Service Now APM, or similar platforms.
• Proven ability to influence across a federated, product-led environment, working with senior stakeholders, architects, engineering teams, and business leaders to shape decisions and drive alignment without direct authority.
• Commercial awareness and strong architectural judgement, with the ability to assess build-vs-buy decisions, total cost of ownership, operational impacts, platform risk, and long-term strategic fit.
• Good understanding of cloud, SaaS, PaaS, IaaS, integration patterns, and enterprise data considerations, alongside experience of emerging technologies, including AI, and their practical application within architectural governance and decision making.
• Excellent communication skills.

• Competitive salary with strong opportunities for growth.
• Chance to influence architecture at enterprise scale within a collaborative and forward-looking environment.
• Competitive benefits package, including pension, holiday allowance, flexible benefits, and support for health and wellbeing.
