• Apply independence, segregation and separation principles to C&I architectural decisions
• Maintain system-level architectural consistency across all major plant islands
• Develop and manage architecture deliverables including the Capella model and system-level design documentation
• Collaborate with systems engineering, plant architecture, safety case and wider integration teams
• Support development and refinement of cross-cutting C&I system requirements
• Ensure architectural changes are captured, reviewed and appropriately integrated into the design lifecycle
• Support architectural verification and validation activities, including reviews
• Present and explain complex architectural concepts to technical and non-technical stakeholders
• Mentor more junior team members contributing to architecture development
