This role is accountable for the design and delivery of end-to-end solution architectures that enable strategic decision-making, policy development, and energy system transformation. The Solution Architect will: * Lead the design and implementation of scalable, secure, and high-performance platforms and solutions supporting energy modelling, forecasting, and scenario analysis. * Ensure alignment between business strategy, policy objectives, and technology delivery. * Work across multiple domains to enable integrated, enterprise-wide capabilities. * The architect will work closely with data scientists, energy modellers, delivery teams, Business Analysts and business stakeholders to ensure the platform enables complex scenario simulations (e.g., decarbonisation pathways, demand forecasting, market simulations) while maintaining extensibility, performance, and governance. This role is Hybrid & can be based from Wokingham or Warwick. We continue to support flexible working where applicable., * Own end-to-end architecture designs across SEP and S&P capabilities, ensuring alignment to enterprise architecture principles, NESO1, and strategic roadmaps, building comprehensive knowledge of the various technology components and the business capabilities they provide. * Confidently engage with stakeholders across the Programme, being empathetic to their needs and challenges, whilst being able to articulate pragmatic solutions in a calm and professional manner. * Work closely with other DD&T colleagues (including Delivery Partners and Suppliers), actively participating in meetings and workshops to help drive solution related conversations to meaningful conclusions. * Map Solution Requirements to Solution Designs, ensuring desired outcomes are supported, and the implications of solutions being implemented are considered from a technology, people and process perspective. * Ensure architectural artefacts produced (including Solution Options and Recommendations, Solution Intents, and High-Level Designs) are approved/endorsed through appropriate Architecture Governance processes, working collaboratively with Integration, Security, Platform and other SMEs to deliver comprehensive solution collateral. * Collateral produced must be written in an easily digestible way, which is fit for purpose of the audience it is aimed at. * Define innovative solutions which consider non-functional requirements (e.g. Security, Performance, Reliability, Scalability, Stability, Data Archival, and Disaster Recovery). * Provide Support and Guidance to Delivery and Test teams to ensure any changes necessary are validated in the context of the wider solution footprint. * Work closely with Team members and other Solution Architects to define, document and resolve technical dependencies and blockers to achieve business value. * Align to strategy, identifying transitional and tactical solutions when strategic options are not defined or available in each timeframe. * Provide specialist technical support across all solutions.
