Description

Joby Overview 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 onward toward certifying the Joby aircraft, scaling our manufacturing, and launching our initial commercial service. Overview As a Mechanical Design Engineering Intern in Joby Aviation's Propulsion Power Electronics team, you will be responsible for the design of world-class power converters. The work environment is dynamic, fast-paced, and challenging. Design engineers drive prototype builds, engineering testing, and product validation. Your day-to-day tasks will involve the design, analysis, and testing of all structural, thermal, environmental, and insulating aspects of converter components and their electrical connections. Power electronics is a field that pushes the limits of a wide breadth of mechanical engineering disciplines. You will be required to apply core principles of statics and dynamics, fluid dynamics and thermal management, mechanics, and vibration analysis. This work is highly multidisciplinary; you will be expected to know or quickly learn basic electrical and magnetic physics, as well as elementary material science. Strong design skills, a ‘first-principles’ approach to problem-solving, and a profound curiosity to learn and develop are must-haves. Responsibilities Mechanical Design: Modeling and designing components and assemblies using 3D CAD software. Engineering Analysis: Performing analyses to optimize designs for various factors, including thermal (CFD), structural (FEA), and design for assembly/test (DFA/DFT). Electronics Packaging: Solving complex packaging issues related to thermal management, electrical isolation, sealing, interconnection, shock/vibration management, and electromagnetic interference (EMI). Prototyping and Testing: Assisting in engineering prototype builds, fabricating components, and designing test jigs and fixtures for validation. Validation and Troubleshooting: Running validation tests, collecting and analyzing lab data, investigating the root cause of failures, and implementing product improvements. Required Heading into junior or senior year of undergraduate degree or above at time of internship Available Summer 2026 Excellent problem solving and communication skills Strong analytical background Experience with hands-on design and testing Proficiency in mechanical design, materials selection, kinematics, troubleshooting, and analysis Proficiency with CAD Desired Additional Information Relocation Assistance: This position does not offer relocation assistance. Candidates must live in the immediate area or relocate at their own expense. The pay range for undergraduate interns, which includes freshman to senior level students, is $22-31/hr. The pay range for graduate interns with a Bachelor, Master, and/or Ph.D. degree is $5,500-$7,800/month. Individual pay is determined by internship role, department, experience, job-related skills, and level of education. Joby is an Equal Opportunity Employer.
