Propulsion Assembly Manufacturing Engineer

Joby Aviation Joby Aviation · Robotics · San Carlos, CA · Manufacturing

Joby Aviation is seeking a Propulsion Assembly Manufacturing Engineer to join their Electric Propulsion Manufacturing Engineering Team. The role involves participating in new product introduction and ramp-up of aircraft powertrains by implementing manufacturing equipment and processes, working closely with cross-functional teams. The ideal candidate will have a strong understanding of manufacturing scale-up, mechanical & electrical fundamentals, equipment, and quality systems.

What you'd actually do

  1. Partner with Design, Quality, Test, and Equipment Engineering to develop world-class propulsion assembly manufacturing processes — driving higher quality, at quantity, and on-time equipment readiness at every build phase
  2. Design, build, and implement custom manufacturing fixtures and tooling to support propulsion assembly, test, and validation — ensuring robust process control, repeatability, and operator ergonomics from prototype through volume production
  3. Participate in design and drawing reviews, ensuring implementation of DFA/DFM best practices during all stages of product development
  4. Drive cross-functional execution with a “one-team” mindset to deliver step-change improvements in safety, quality, throughput, and ergonomics from prototype through ramp to volume production
  5. Lead the equipment selection and process development for the bring-up, qualification, and deployment of advanced manufacturing processes like dyno testing and coolant filling
  6. Author and release high-clarity manufacturing procedures — then drive successful adoption on the production line to ensure flawless build execution at scale
