• Understanding of prompt engineering, model selection, and LLM capabilities/limitations

Proven AI Impact

• Achieved measurable productivity improvements using AI in development

• Implemented AI-assisted refactoring, test generation, or documentation at scale

• Experience with AI code analysis and automated remediation

• Track record of shipping production systems built with AI assistance

Culture & Leadership Style – What Matters Most

• Delivery-focused: Ship working modernised services, don't just build tools

• Hands-on: Write code daily, don't just architect or advise

• Pragmatic: Use AI to go faster, not to be clever

• Teacher through doing: Others learn by seeing your PRs and shipped work

• Measurement-driven: Track your AI productivity gains and share data

• Collaborative: Work across divisions and time zones professionally
