Contribute to technical discovery and design, balancing user value, delivery speed, risk, cost and maintainability
Build automated tests at unit, integration and regression levels with proportionate manual testing where needed
Take part in peer reviews of code, designs and documentation, giving specific feedback on human and AI-generated work
Use approved AI coding tools productively and responsibly, reviewing outputs for correctness, security and licensing before release
Break work into clear tasks, specifications and prompts with appropriate review points and traceability
