About The Position

As Engineer II with the Retail Media Network Ad Engineering, you will be responsible for delivering complex product features that are well-tested, scalable, and production ready. This role requires minimal oversight and expects the engineer to plan and execute coarse-grained features while breaking down large problems into manageable parts. You will support backend engineering at scale, with a solid understanding of cloud infrastructure, microservice architecture, and system performance. You will collaborate closely with product managers, designers, and fellow engineers while demonstrating initiative and ownership across the stack. This is a role for engineers who are eager to grow into technical leaders while contributing meaningfully to business outcomes. This role is hybrid, which means you will work some days on site at a Best Buy location and some days virtually from home or other non-Best Buy location. The specific work arrangements vary by role and team. The recruiter or hiring manager will provide more details during the hiring process. For this role, you must be located within a drivable distance to our office in Richfield, Minnesota.
