Thermal Engineer

Joby Aviation is seeking a passionate thermal engineer to join our growing team. The position requires a strong understanding of refrigeration and heat pump theory. The applicant is expected to have hands-on experience designing, analyzing, and testing two-phase thermal systems. Familiarity with internal flow CFD is also desired. This position is rewarding, as the engineer will promptly see their work implemented on real-world applications due to the fast pace of Joby Aviation.

Responsibilities: 
  • Scope and design cooling strategies for cabin air conditioning and refrigeration cycle.
  • Leverage low-fidelity methods (1D analysis) to perform quick sizing of thermal components for use in two phase fluid cycles.
  • Prototype and test conceptual designs of refrigeration cycles.
  • Interface with team members and external suppliers to understand requirements and constraints of HVAC systems.
  • Develop Matlab/Simulink thermal model of propulsion cooling system.
  • Deliver performance assessments and sensitivities of cooling system.
  • Generate test procedures, create prototypes, and perform experimental validation.
  • Produce supporting documentation for FAA aircraft certification. 

Required: 
  • BSc. in relevant engineering discipline.
  • 3 years experience (including MS).
  • Expert knowledge of thermodynamic theory, specifically real two-phase working fluids.
  • Strong mathematical background.
  • Excellent problem solving and communication skills.
  • Automotive or Aeronautical Industry experience in designing 2 phase cycles and heat pumps.

Desired: 
  • MEng/PhD in fields of HVAC, vapour compression cycle, two phase systems.
  • 2+ years hands-on experience performing detailed refrigeration/heat pump design and testing for aircraft or automotive.
  • 5+ years of working experience in relevant industry (including MS).
  • Expert knowledge of Simulink/Simscape.
  • Critical eye for customer thermal comfort in real life scenarios.
  • Hands-on experience working within aircraft certification programs.
  • Strong knowledge of FAR 23 and 27. 
  • Experience optimizing heat exchangers in a mass-constrained environment. 
  • Proficiency with CAD (CATIA), CFD (STAR-CCM+), and FEA (Abaqus) software.
