Mechanical Design Engineer Matic

Menlo Park, California

It also includes an 8pm call with a supplier in Asia, a tolerance study nobody's excited to run, a test fixture you build with your own hands, a life test that keeps failing for boring reasons, a return unit you tear down to find out why a clip is cracking, a drawing you update for the fourth time, and a part you chase through customs because the line is down without it. Fluency in at least one high volume process (injection molding, die casting, stamping, or metal injection molding) at the level of gate placement, draft, knit lines, sink, and warp, not just textbook definitions.
