What are the responsibilities and job description for the CNC Shop Manager I position at Inversion?
Turning Space into a Transportation Layer for Earth
Who We Are
Eras of humanity can often be defined by a dominant transportation mode - horse drawn chariots, ocean going boats, or aircraft. These were spurred by a small group of people rigorously focused on building technology to achieve faster access to more of the world. We seek to usher in a new era of humanity defined by universal access to the whole globe free of borders and the presence of a routine way from space to Earth. To do this, we are building highly maneuverable re-entry vehicles that can loiter in orbit before precision landing back on Earth.
Position Overview
We are seeking a CNC Shop Manager who is both a strong people and operations leader and a hands-on CNC programmer. This is a player-coach role responsible for the daily performance of a six-machine aerospace machining environment, including staffing, scheduling, cost control, policy and procedure development, and direct CAM programming support.
The ideal candidate is equally comfortable building shop structure and jumping into Mastercam/other CAM software to program complex parts, prove out jobs, and standardize setups.
