  • Perform PCB soldering, including fine-pitch component assembly (e.g., 0402 SMT) under a microscope.
  • Execute optical component assembly and testing procedures, often in a cleanroom environment.
  • Debug custom PCBs based on schematics and perform rework to determine root cause of failure.
  • Work closely with engineers and other technical staff to develop and document new processes.
  • Engage in 3D printing and prototype development.
  • Procure parts, manage inventory, and work with suppliers to build samples.
  • Perform various hands-on lab work, assembly, and testing tasks.
What You’ll Bring
  • Graduation from a technical college with a mechanical or electrical technical diploma or equivalent work experience.
  • Extremely hands-on with strong computer skills and the ability to efficiently pick up new software.
  • Strong mechanical aptitude; comfortable using microscopes and working with small, precision parts.
  • Careful attention to detail and a logical, clear approach to problem-solving.
  • Exceptional written and verbal communication skills.
  • Nice to Have: 3D printing experience.
  • Attributes: A keen attitude, hardworking, willing to learn and explore, and passionate about cool technology used in disruptive new consumer electronics devices.
Why Optopax?
  • Work at the intersection of optics, AI, and embedded systems.
  • Support the development and manufacturing of real hardware that ships.
  • Join a small, high-impact team where your contributions matter.
