• Ensure alignment with relevant legislation, information governance requirements and internal technology standards.
• Establish repeatable architecture controls and decision records.
• Support training, coaching and enabling teams to adopt consistent engineering practice.

Technical Delivery Support

• Provide expert guidance to delivery teams on architecture constraints, recommended patterns and implementation options.
• Support troubleshooting, risk identification, technical assessments and proof-of-concept design activities.
• Contribute to sprint ceremonies and delivery planning to ensure architecture is Embedded across the life cycle.
• Work with delivery teams to balance pragmatic delivery with long-term maintainability.

Essential Skills & Experience

• Strong experience as a Technical Architect or Lead Engineer within large public-sector, government or regulated environments.
