.

Imagine a piloted air taxi that takes off vertically, then quietly carries you and your fellow passengers over the congested city streets below, enabling you to spend more time with the people and places that matter most. Since 2009, our team has worked steadily to make this dream a reality. We’ve designed and tested many generations of prototype aircraft capable of serving in a network of electric air taxis.

We’re looking for talented, committed individuals to join our team as we push onward toward certifying the Joby aircraft, scaling our manufacturing, and launching our initial commercial service.

Joby Aviation is seeking an experienced CNC Prototype Machinist to join our subtractive prototyping team. This individual’s role is to setup, operate, program, make fixtures, jigs, test articles, and flight components while collaborating with engineers and other technicians through hands‑on experience. You will be responsible for the entire process of CNC operations from start to finish cutting a wide variety of metals and plastics.

A willing attitude is very important for this position and goes a long way when thinking through a variety of solutions to complete jobs on time due to the fast pace of parts flowing through the shop. This position is hands‑on experience; we aim to attract, retain, develop and motivate talent that possess the skills and leadership necessary to grow our team.
