Responsibilities

Define and drive reusable, reliable, and scalable back-end architectures across the Cars Commerce platform and integrations.
Lead the design, work breakdown, and development of high-performance, API-based backend services that meet service-level objectives (SLOs) and scale with growing business demands.
Champion technical excellence by promoting best practices in system design, operational maturity, and engineering quality across the team.
Work closely with engineering, design, and product partners across teams to align on back-end strategies and standards, elevate the use of back-end, API and integration consistency, and reduce duplication.
Serve as a back-end thought leader and mentor, coaching other engineers and shaping team/department-wide best practices.
Treat components and libraries as products. Develop excellent documentation, innovative usage patterns, and internal developer experience.
Collaborate with backend developers to integrate UIs with APIs. While your focus is back-end, you’re comfortable navigating the full stack.
Participate in an on-call rotation, providing prompt incident resolution and conducting postmortems to improve system reliability.
