    • FEA (Ansys and Solidworks Simulation)
    • Hand calculations 
    • Physical load testing 
  • Prototyping and testing mechanical and electro-mechanical systems
  • Preparation of detailed systems documentation 
  • Test fixture and ground support equipment development and deployment 
  • Analysis of thermal and thermoelastic load cases
  • Peer reviews of mechanical drawings
  • Qualification of satellite subsystems and full satellites
  • Providing production support to the manufacturing team
  • Assisting other team members from multiple disciplines achieve their goals

Basic Qualifications / Experience:

  • Degree in Mechanical Engineering or equivalent course or work experience
  • Aerospace experience

  • Minimum 3yr experience in a similar role
  • Experience modelling mechanical systems in Excel, Matlab, or Python 
  • Precision machined parts design (including material & coating selection)
  • CAD modelling experience
  • Excellent written and verbal communication

Preferred Qualifications / Experience:

  • Environmental testing (vibration, thermal, thermal-vacuum) 
  • Solidworks Simulation and Ansys Mechanical experience
  • Thermal and thermoelastic analysis of mechanical systems
  • Mechanical inspection techniques
  • Design and drafting experience (preferably in Solidworks) 
  • Electronics theory (communication interfaces, PCB layout principles)
  • Basic software skills (C, python, scripting)

Please note that our application process includes a challenge. Our motto is 'show me the data,' so if you make it to the challenge round, you'll have time to give us your best work on a problem that lets you put your skills on display or showcase your existing portfolio.
