Mechanical Engineer

San Jose, California, United States · Engineering expand job description ↓



As an ideal candidate, your strong mix of technical breadth and depth allows you to work cross-functionally to tie mechanical assemblies, optics, electronics, and computing power into the world’s highest resolution holographic display. We are seeking a practical mechanical engineer who doesn’t mind getting his or her hands dirty, and likes to work on many aspects of a project at the same time. You will work with other MEs, Optical Engineers, Optical Test Engineers, Electrical Engineers, and System Engineers to build the world’s first convincing holographic display.


Essential Duties and Responsibilities

  • Design, directly fabricate, assemble, and test prototypes.
  • Design fixtures for optomechanical systems which may combine optical components, display devices, electronic components, cooling system, support structures, and kinematic features for location and alignment.
  • Design for precision mounting, alignment, and interlock of individual display panels for a modular video wall system
  • Develop fixtures for test of optical components, optical subassemblies, and electrical systems
  • Develop motion control systems including motors and translation stages

Other Duties and Responsibilities

  • Perform some direct machining of critical parts, and assemble and test prototype optomechanical systems



  • Degree in Mechanical Engineering, or commensurate experience
