- Review functional and technical requirements to identify gaps, and limitations, propose simplifications and communicate ideas effectively with cross-functional teams
- Take accountability for code quality - whether produced by agentic AI tools or fellow engineers - through rigorous code review and pull-request feedback, ensuring unit testing and departmental guidelines are consistently met. Where no formal guidelines exist, work with peers to formulate and enforce such guidelines
- Develop and improve build, deployment and test automation within your team
- Help identify, prioritize and resolve technical debt within your team
- Collaborate with your team to ensure work items are well defined and understood, and that value is delivered with quality on every sprint




- Investigate and resolve customer issues escalated to engineering, and feed what you learn back into the product
- Track emerging macOS and security technologies and put forward improvements to the team’s tools and development processes
- Become the go‑to development expert for at least one area of the product, deepening that expertise over time
