Joby Overview

Located in Northern California, the team at Joby Aviation is driven by our goal of creating an affordable, all-electric air transportation system. 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 onwards toward certifying the Joby aircraft with the Federal Aviation Administration, scaling our manufacturing, and preparing to launch commercial service in 2025.


Joby Aviation is seeking an all-around mechanical/aerospace engineer with strong technical fundamentals, practical ability and problem-solving skills to join our Powertrain team. As a key member of a high-performance team you will develop electric turbocompressors supplying pressurized air to hydrogen fuel cell systems that provide electrical power to aircraft propulsion systems. As part of a cross-functional team you will be responsible for the end-end product development cycle of your components with an emphasis on rapidly iterating through design/build/test cycles to achieve our ambitious performance and timing goals.


  • Own the complete product development cycle (conception, design/analysis, prototype build/test iterations, certification, SOP) for one or more turbocompressors
  • Perform all 3D & 2D mechanical design work (CAD)
  • Collaborate with teammates who:
  • Are subject matter experts in electrical, aerodynamic, mechanical and thermal design/analysis to incorporate their expertise into an optimized product
  • Are responsible for adjacent products and higher-level systems to ensure that the overall system delivers the highest performance, reliability and safety with the lowest weight, size & cost.
  • Design & Build Prototypes, including assembly fixtures and tools, document part & build quality
  • Test Prototypes, including designing and building required testing fixtures & setups as well as data acquisition and reporting
  • Actively support testing of higher-level systems, up to and including aircraft flight testing


  • S. in Mechanical or Aerospace Engineering (or equivalent)
  • Strong Engineering & Technical Fundamentals
  • Excellent problem solving & communication skills
  • High skill level in 3D & 2D Mechanical Design & CAD (including GD&T and DFM)
  • Basic CAE skills (FEA, CFD, engineering programming, LabView, Matlab/Simulink)
  • Practical hands-on experience building & testing new product designs

This position must meet US export control compliance requirements, therefore a candidate must qualify as a “US Person” as defined by 22 C.F.R. § 120.15. “US Person” includes US Citizens, lawful permanent residents, refugees, or asylees.


  • Experience working on small fast-paced independent teams

  • Relevant (e.g. rotating machinery) work experience
  • Basic Program Management experience

  • Compensation at Joby is a combination of base pay and Restricted Stock Units (RSUs). The target base pay for this position is $79,900-$130,900. The compensation package offered will be determined by location, job-related knowledge, skills, and experience.
