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. At Joby, we've been working to make that dream a reality since 2009 and we're now in the final stages of certifying our aircraft with the FAA. With plans to launch our aircraft in the US and Dubai, we're now scaling manufacturing and preparing for the launch of our commercial service.
OverviewJoby Aviation is building electric vertical takeoff and landing (eVTOL) aircraft. Before our electric propulsion systems, energy storage systems, and flight electronics fly, they are mounted, powered, cooled, and verified on hardware designed by our Equipment Design Team.
As a Senior Design Engineer, you will design the test stands, fixtures, and electromechanical systems used to verify propulsion systems, power electronics, battery and energy storage systems, and flight-critical electronics. You will own designs from concept through fabrication, integration, and formal release, and see your hardware running in the lab within weeks, not years.
ResponsibilitiesDesign test stands and fixtures for electric propulsion hardware, energy storage systems, and flight electronics, from detailed CAD through drawing packages, BOMs, and assembly instructions
Design the electromechanical elements: rotating machinery mounts and couplings, battery and module mounting, power and control wiring, enclosures, and cooling and thermal interfaces, and produce the schematics and wiring documentation to go with them
Work with Propulsion, Energy Storage, Avionics, Software, and Airframe engineers to capture component behavior, system architecture, and operating conditions
Design to high-voltage and high-power safety requirements, including interlocks, guarding, containment, venting, and safe lab integration for energy storage testing
Run stress, thermal, and vibration analysis to make sure loaded and rotating fixtures are safe and accurate
Lead integration and commissioning, adapting designs on the fly as hardware evolves
Procure parts and coordinate fabrication with internal and external shops, and build or modify hardware yourself when speed matters
Review teammates’ designs and mentor engineers earlier in their careers
Release designs through formal configuration management and change control
B.S. in Mechanical Engineering, Mechatronics, Electrical Engineering, or related discipline with 5+ years of relevant experience, M.S. with 3+ years, or equivalent practical experience
Strong mechanical design skills: CAD modeling and manufacturing drawings with GD&T (SolidWorks, NX, CATIA, Creo, or similar)
Experience creating electrical schematics and wiring documentation for power and control systems (AutoCAD Electrical, EPLAN, Altium, or similar)
Experience with high-voltage or high-power systems such as batteries, motors, drives, or power electronics, with an understanding of safe design practices
Experience designing fixtures for rotating machinery or electromechanical assemblies (motors, drives, gearboxes, dynamometers)
Comfort working hands-on with hardware in a lab or shop environment
- Strong trade-off and decision-making skills under schedule pressure, with clear communication across disciplines
- Experience with thermal or fluid systems such as liquid cooling loops, heat exchangers, or thermal interfaces
- Practical shop experience (lathe, mill, welding)
- Experience with battery or energy storage test setups (cyclers, environmental chambers, abuse or safety testing)
- Familiarity with sensors, instrumentation, or data acquisition (not required)
- Hardware-in-the-loop test setup experience
- Finite element, thermal (CFD), or modal analysis for test fixtures
- Experience taking projects from concept through commissioning
- Familiarity with FAA certification or safety-critical testing
- Background in EV powertrain, battery test, dyno or test cell, motorsport, or rapid prototyping
Compensation at Joby is a combination of base pay and Restricted Stock Units (RSUs). The target base pay for this position is $141,600 - $194,700/yr. The compensation package will be determined by job-related knowledge, skills, and experience.
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.
