Collaborate with the Product Manager and other engineers to refine requirements and translate business needs into robust technical solutions.
Uphold and improve the team's code quality standards, providing detailed feedback and mentorship through code reviews.
Document the solutions we build and ensure our APIs and services are well understood by consumer teams.
