What You’ll Do

• 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.
