Manufacturing Engineer - Motor

Joby Aviation • San Carlos, CA

4d • $81,300 - $135,300 • Onsite

About The Position

Joby Aviation is seeking a collaborative and process-oriented Manufacturing Engineer to join our Electric Propulsion team in San Carlos, CA. In this role, you will bridge the gap between complex design engineering and scalable volume production. Beyond technical expertise, the ideal candidate is a champion of operational excellence who excels at communicating with diverse stakeholders—from design engineers to production technicians. You will participate in the NPI (New Product Introduction) and ramp-up of the Joby aircraft powertrain, ensuring that our manufacturing systems are as reliable, safe, and efficient as the aircraft itself.

Requirements

• B.S. in Mechanical Engineering (or related) with 2+ years of experience, or M.S. with 1+ year
• Exceptional interpersonal skills with the ability to build trust and influence cross-functional teams without direct authority. You enjoy being on the shop floor and value the insights of technicians and operators
• Demonstrated success of balancing engineering precision with operational reality. You are motivated by stable processes, statistical control, and efficiency rather than just novel technical fixes
• Strong foundation in mechanical engineering principles, with hands-on experience in process development, validation (IQ/OQ/PQ), and root cause analysis
• Ability to thrive in a fast-paced environment, bringing structure to ambiguity rather than just reacting to it.
• Proficient in CAD (Solidworks or CATIA)
• Willingness to travel up to 10% as needed

Nice To Haves

• Proficiency in SPC (Statistical Process Control) tools (e.g., JMP, Minitab) and data-driven problem solving.
• Proficient in GD&T per ASME Y14.5 for complex tolerance stack-up analysis.
• Experience with electric motor assembly, power electronics, or complex electro-mechanical systems.
• Experience manufacturing in regulated sectors such as Aerospace (14 CFR Part 21), Automotive (TS16949/IATF 16949), or Medical (ISO 13485).

Responsibilities

• Partner closely with Design, Quality, Test, and Equipment Engineering to develop world-class motor manufacturing processes. You will act as the voice of manufacturing, driving Design for Manufacturing (DFM) feedback to ensure high yields and seamless manufacturing readiness
• Champion a "safety-first" and "quality-always" culture. Lead cross-functional initiatives to deliver step-change improvements in throughput, ergonomics, and repeatability from prototype to volume production
• Own the evolution of the production line. Utilize Lean principles to identify constraints, introduce automation, and optimize test performance across welding, winding impregnation, rotor/stator build, and final motor test
• Translate complex technical requirements into high-clarity, user-friendly Standard Work instructions. You will not just write procedures, but train and mentor production staff to ensure successful adoption and flawless execution.
• Maintain full ownership of assigned manufacturing processes, utilizing data to drive decisions from initial deployment through sustained production and validation.

Benefits

• Joby also offers a comprehensive benefits package, including paid time off, healthcare benefits, a 401(k) plan with a company match, an employee stock purchase plan (ESPP), short-term and long-term disability coverage, life insurance, and more.
