An opportunity to play your part: Ready to shape the future of energy technology in Ireland? Join Centrica as a Domain Architect and take the lead in driving end-to-end architecture across a rapidly transforming landscape - from next-gen energy platforms to Salesforce and Dynamics 365 enhancements. This is a high-impact role where you'll partner with Product, Engineering and Delivery teams to design smart, scalable solutions that elevate customer experience, boost performance and simplify our tech estate. You'll bring big-picture thinking, make commercially savvy decisions, and help build a culture of architectural excellence - coaching others and turning strategy into real-world outcomes. If you love solving complex challenges and making things work at scale, this is your moment.

The Day to Day: Define and maintain the target architecture for our Irish business lines - Consumer and Commercial propositions. Ensure these roadmaps align to the enterprise standards and the strategic direction set by Retail Architecture. Provide clear architectural direction to guide the transition to our next technology platforms and the required simplification/convergence on the legacy. Design architecture around the outcomes that matter for the business functions - customer experience, operational efficiency, regulatory compliance (CRU/industry), and commercial performance. Ensure architectural decisions directly support the OKRs for Billing, Customer Service, Market Operations, and Field Services. Challenge solutions that create unnecessary complexity or cost. Champion the use of strategic platforms and shared integration/API frameworks. Ensure the business consumes shared capabilities where appropriate, while clearly identifying where the Irish market requires local differentiation. Drive reuse of Centrica-wide accelerators and prevent divergence from Retail architectural guardrails. Operate within Centrica's architectural guardrails and decision rights. Own architecture expertise within the Irish domain, escalating only when choices impact cross-market capabilities, enterprise platforms, or introduce strategic risk. Ensure all designs meet enterprise NFRs, security standards, and data protection obligations. Design with an understanding of Irish industry processes (e.g., market flows, Gas/Elec market interactions, DSOs/TSOs, regulatory cycles), integrations to legacy BGE systems, and upstream/downstream impacts. Ensure architectures are robust, operable, cost-efficient, and able to scale for customer growth and increased digital adoption. Work closely with the Platform, Product, and business programme teams to ensure designs are buildable and grounded in delivery reality. Adapt architectural direction as the architecture evolves. Measure architectural effectiveness by delivery progress and post-go-live adoption, not documentation. In partnership with Product and Finance, ensure architectural options factor in total cost of ownership, cloud economics, licensing, vendor risk, regulatory impacts, and operational cost-to-serve. Provide clear analysis to support build-vs-buy decisions, platform extensions, or local differentiators required for the Irish market. Be the trusted architectural advisor for business leadership, including Product Directors, Programme Directors, Engineering Leads, and Technology Leaders and the wider Centrica Retail organisation. Communicate architectural decisions clearly and influence outcomes through expertise, not hierarchy. Coach and support the Solution Architects and engineers working across retail wide initiatives. Promote clarity, quality, platform reuse, and continual improvement.
