Principal Mechanical Engineer

Also called: Senior Staff Mechanical Engineer, Lead Mechanical Engineer

Senior expert who owns the hardest mechanical design calls on big products and mentors other engineers.

A day in the life

You start the morning reviewing a junior engineer's design for a new pump housing and catch a spot where it will crack after a few thousand cycles. After lunch you sit with managers to decide whether a product launch slips a month. Late in the day you sketch a clever fix for a vibration problem nobody else could crack.
