Company Details

We plan to save a billion people an hour a day

Joby Aviation is seeking a passionate engineer to join our Powertrain team in San Carlos, CA to support development of the Joby S4.  The individual would be responsible for building and maintaining full and/or reduced order heat transfer models to support mechanical design & optimization efforts.  This role would contribute to aero/thermal aspects across various teams such as environmental control, battery, system electronics and propulsion.  Heavy use of STAR-CCM+ envisioned for near-term workflow so tool proficiency is preferred.


  • Determine appropriate model complexity to support design decisions & timelines.
  • Analyze component & system level performance with keen eye on improvements.
  • Collaboratively define system architecture & key system requirements.
  • Guide test procedures for model correlation & verification.


  • Strong fundamentals in thermodynamics, fluid dynamics and aerodynamics.
  • Working knowledge of at least one CFD analysis toolkit such as STAR-CCM, OpenFOAM, Ansys, etc.
  • Experience with building large CFD models with complex CAD geometry.
  • Self-starter who can effectively balance multiple project timelines & priorities

Pursuant to various local, state, and federal regulations, you must show proof of your full COVID-19 vaccination status prior to your start date.  Exemption requests are available for bona fide religious and medical circumstances.


  • Proficiency with STAR-CCM and 3DExperience (CATIA).
  • Postgraduate qualification & relevant work experience in automotive or aviation industry.
  • Skilled in thermal resistance modeling and transient heat transfer analysis.
  • CFD experience in air flow distribution, heat transfer, and fan components.
  • Familiarity with manufacturing constraints to inform cost-effective & manufacturable design recommendations.
  • Scripting knowledge (Python/Java/Matlab) for simulation automation and data analysis.
  • Experience with component or vehicle level instrumentation, testing, & analysis.
