Staff Mechanical Engineer - Charging Systems

We're looking for a Staff Mechanical Engineer who can lead the development of complex GSE systems end-to-end and raise the technical bar across the team.

You'll work across power delivery, fluid handling, thermal management, and structural packaging - and you'll be the primary mechanical engineering interface for our electrical, controls, and systems teams, external vendors, and field operations.

This is not a position for someone who hands off to others at the hard parts.

Responsibilities Own the mechanical architecture of charging and thermal conditioning systems - from requirements definition and system sizing through detailed design, build, and validation Design fluid handling systems including coolant loops, pressurized reservoirs, and dispenser assemblies; specify components, author P&IDs, and manage thermal and hydraulic performance Package high-power electronics and control circuitry into field-deployable enclosures in tight collaboration with electrical, firmware, and compliance engineers and contract manufacturers Produce complete engineering documentation: manufacturing drawings, BOMs, assembly instructions, P&IDs - in CATIA (3DEXPERIENCE) Own prototype procurement - source hardware, select vendors, and coordinate fabrication with machine shops and contract manufacturers through the prototype phase; partner with Supply Chain for production-scale builds Lead design validation and testing programs; support the compliance team in providing mechanically sound, well-documented hardware for NRTL certification Support GSE deployments in the field, globally - including installation, commissioning, and issue resolution at operating sites Mentor senior engineers, provide architectural guidance, and help establish design standards and validation frameworks for the team Required B.S. or higher in Mechanical Engineering or closely related discipline 8+ years of relevant engineering experience, with clear evidence of owning complex hardware programs Demonstrated experience designing and building fluid handling systems - coolant loops, pneumatic circuits, pressurized assemblies, or similar Experience designing power electronics enclosures and electromechanical assemblies for low-to-medium volume production Proficiency in a professional CAD package; CATIA (3DEXPERIENCE) strongly preferred Able to produce complete, manufacturing-ready documentation: drawings, BOMs, P&IDs, assembly instructions Hands-on - comfortable in a shop, able to debug hardware in person, and willing to do it Strong cross-functional communication skills; able to drive alignment across mechanical, electrical, controls, compliance, supply chain, and operations teams Willingness to travel internationally up to 15-20% of the time for deployments and site support Desired Experience with DC fast charging infrastructure or high-power electrical systems (100+ kW) Familiarity with requirements and design constraints imposed by NRTL certification processes (TUV Rheinland , UL) - you don't need to own the certification path, but you should know how to design for it Background in refrigeration or active thermal management systems (chillers, heat exchangers, fluid loops with refrigerants such as R32) Experience working with and technically managing external contract manufacturers and machine shops through prototype builds Aerospace, defense, or other highly regulated hardware background Comfort operating in environments where the standards are being written alongside the hardware Additional Information Compensation at Joby is a combination of base pay and Restricted Stock Units (RSUs).

The target base pay for this position is $161,200 - $221,700/yr. The compensation package will be determined by job-related knowledge, skills, and experience.
