You are an experienced, hands-on mechanical engineer who thrives on owning a subsystem end-to-end rather than checking off assigned tasks. You're comfortable being the technical interface with contract manufacturers, running root-cause investigations, and coordinating across Mechanical, Electrical, Optical, Firmware, Software, Manufacturing Engineering, Design Transfer, and Quality to get a product through verification and into manufacturing. You take full ownership and accountability for your subsystem's performance, manufacturability, reliability, and cost throughout its lifecycle, and you proactively flag risks before they become schedule problems.
