  • Define approaches for content modelling, transformation, migration automation and validation.
  • Coordinate engineering activities, resolve complex technical challenges and manage dependencies and delivery risks.
  • Remain hands-on where required, particularly for complex implementation, technical spikes and critical problem-solving.
• AI-First Engineering Leadership
  • Champion an AI-first engineering mindset, encouraging the team to proactively use AI to improve software delivery.
  • Establish practical spec-driven development approaches, ensuring clear, testable specifications guide implementation and validation.
  • Identify opportunities to apply AI to Sitecore analysis, content mapping, migration automation, code modernisation and testing.
  • Guide developers in the effective use of AI coding assistants and automated engineering workflows.
  • Establish appropriate review, security and quality practices for AI-generated code and migration outputs.
  • Drive experimentation, knowledge sharing and measurable improvements in team productivity through AI adoption.
