Are you passionate about bringing hardware products to life at scale? We are hiring a Manufacturing Test Engineer who combines hands-on mechanical intuition with strong software skills to own the end-to-end factory test infrastructure for Bee's wearable AI devices. In this role, you will design, develop, and maintain the manufacturing test stations that validate every Bee device coming off the production line — from board-level functional tests through final assembly verification. You'll own the full test software stack (Python on Linux), evaluate and improve mechanical test fixtures, analyze production yield data, and work directly with our contract manufacturer in China to resolve issues in real time. This is a role where you'll write code in the morning and troubleshoot fixture tolerances in the afternoon. Bee is a personal AI company acquired by Amazon in 2025. The team operates with startup speed and full autonomy while leveraging Amazon's world-class resources.
