• Stakeholder Engagement: Collaborate with business stakeholders, project delivery teams, infrastructure specialists, developers and fellow architects to translate business requirements into effective technical solutions.
• Cyber Security: Embed security by design into technical architectures, ensuring solutions align with enterprise security policies and regulatory expectations.
• Integration & Interoperability: Support integration planning across a complex, multi-supplier environment, ensuring technology components work together effectively.
• Architectural Governance Forums: Contribute to the Architecture Review Board and other governance processes, providing technical recommendations and challenging designs where necessary.
• Technology Innovation: Assess emerging technologies and digital transformation opportunities, recommending approaches that improve efficiency, resilience and long-term value.
• Risk Management: Identify and assess technical risks, resolve design challenges where possible and elevate significant issues to the Technical Assurance Manager.
• Extensive experience in a Technical Architect or equivalent architecture role within a large-scale, complex or regulated environment.
• Strong technical knowledge of enterprise architecture, including cloud technologies, infrastructure, networks, integration and application platforms.
• Proven experience designing and assuring secure, scalable, reliable and cost-effective technical solutions.
• A track record of providing architectural oversight and assurance for solutions delivered by third-party suppliers.
• Experience working across multi-supplier delivery environments, coordinating technical designs and ensuring interoperability.
• Strong understanding of cyber security principles and their application within complex or regulated organisations.
• Excellent stakeholder management and communication skills, with the ability to influence senior technical and non-technical audiences.
• The ability to assess technical risks, challenge proposed solutions constructively and make informed architectural decisions.
• Security Check (SC) clearance, or willingness to undergo the required vetting process.
• Experience within the nuclear, energy or another highly regulated sector.
• Knowledge of large-scale infrastructure or major capital project delivery.
• Professional certifications such as TOGAF, ITIL or cloud certifications covering AWS, Microsoft Azure or Google Cloud Platform.
• Familiarity with enterprise digital transformation, emerging technologies and modern architectural best practices.
• Experience supporting major infrastructure programmes involving complex supplier relationships.
