Ensure the team builds software that is architecturally consistent and of high quality to reliably meet customer needs. Support a highly available service used by millions of users daily, ensuring reliability, scalability, and maintainability. Help cultivate an environment where team members are empowered and demonstrate a strong sense of ownership and belonging. Help ensure that individuals on the team are learning, growing, and advancing in their respective careers. Mentor, pair, and delegate work to encourage the professional and technical growth of your team and those around you.
