Software Development Torrance, California 1,001–5,000 employees Founded 1995 Public Company

CarParts.com operates a high-volume e-commerce parts platform with a Python + AWS stack heavy on Lambda, FastAPI, and Docker for transaction processing. Active projects span ML-driven inventory automation and pricing logic, paired with a workforce-planning and labor-forecasting focus—suggesting internal friction between supply-side accuracy (inventory discrepancies, warehouse efficiency) and demand-side optimization (margin, SLAs). The hiring distribution is heavily weighted to ops and logistics roles, indicating growth is constrained by fulfillment execution rather than feature velocity.
