Mechanical Engineer - Traction Systems

We're looking for a talented Mechanical Engineer to design components and test the system with a focus on the Traction System based onsite at our Downtown Los Angeles HQ office. In this role, you'll work with fellow engineers and technicians to bring up new designs in our lab and run vehicles on our dedicated test track just outside the city. This is an opportunity to engage early with new designs, making a big impact on the direction of the technology. Ideal candidates have experience developing products on first principles and engineering skills and have a desire to expand their responsibilities to own hardware designs. 

Responsibilities  

• Derive architecture, meet and present technical direction, build consensus. Work closely with multi-disciplinary engineering teams
• Full life cycle hardware development including requirements capture, prototyping, design validation, and manufacturing readiness
• Create and execute design of experiments for decisions on architecture, component selection, and manufacturing processes
• Support manufacturing, vehicle integration, and validation
• Design and develop electric traction systems (motors, inverters, gearbox)
  • Determine motor requirements and sourcing hardware
  • Develop motor capabilities and test campaigns for acceptance and validation
  • Design interfacing systems (cooling, mechanical coupling, mounting)

Basic Qualifications 

• BS in Mechanical Engineering or similar Engineering discipline
• 3+ years of professional or project experience in hardware development, machine design, or validation
• Experience drawing creation and GD&T, structural analysis, selection of materials and processes, understanding of failure mechanisms, and analytical/scientific programming (i.e. Python, Matlab, Simulink, Excel)
• Experience with at least one commercial CAD tool (Solidworks, Fusion 360°, etc)
• Experience with at least one commercial FEA or multi-physics simulation package (i.e. Simulink, Solidworks, NASTRAN, ABAQUS, ANSYS)

 
Preferred Qualifications  

• 5+ years of experience in hardware development, machine design, or validation
• Master’s Degree in Mechanical Engineering or similar Engineering discipline
• Experience in one or more of the following areas
  • Design and qualification for various forms of steel structures including fabricated weldments, forgings, and castings
  • Static and dynamic analysis, including fatigue life. Understanding of material selection and experience with process specification
  • Component design, component specification, mechanical integration, or modeling of electric traction systems. Components include HV batteries, traction inverters, traction motors, gear assemblies
  • Electronics and sensor packaging including requirements for high voltage isolation, heat dissipation, vibration isolation, water sealing, and manufacturability
  • Enclosure designs in sheet metal, stamping, die casting, and/or injection molding
  • Designing fluid systems including hydraulics and thermal control systems. Schematic design, component requirements derivation, component characterization, and system validation
