Joby Aviation is seeking a motivated and organized engineer as an intern to join the Powertrain Modeling and Simulation team. During this internship, you will be embedded with a small team of engineers, and will contribute directly towards the design, validation, or test development of our revolutionary electric air taxi. Joby is looking for candidates with experience developing battery models and algorithms. The ideal candidate is energetic, has a positive attitude, is flexible and excited about learning. Expect an internship that is similar to a job you would have when you graduate. 


  • Analyze battery algorithm/model performance and sensitivity from data collected at various levels (e.g. cell level, battery pack level, aircraft level)     
  • Analyze battery limits through simulations based on performance requirements      
  • Develop subcomponent models for battery system simulator   
  • Develop tools to make processing and reporting on data as consistent and easy as possible   
  • Work closely with engineers to understand the test and clearly present on the results 


  • Pursuing MS/PhD in Electrical Engineering or Mechanical Engineering or science degree
  • Knowledge of battery electrochemistry and the respective electrical and thermal behavior. 
  • Knowledge of Li-ion battery electrical & thermal modeling 
  • Experience with developing battery state estimation algorithms 
  • Experience with Matlab/Simulink 
  • Strong problem solving and communication skills 


  • Knowledge of data analysis with common Python packages (e.g. Numpy, Pandas)
  • Knowledge of common Li-ion battery degradation mechanisms (e.g. SEI growth, lithium plating)
