Test Technician

Essential Functions • Pre-power checks — Before anything is switched on, check wiring continuity, insulation, polarity and grounding, and confirm the printer is built to the correct configuration. 

• Bring-up (Level 600) — Power up and verify each subsystem in sequence; perform pressure and leak checks on the gas, vacuum and coolant lines. 

• Calibration and software — Calibrate sensors, gauges, temperature controls and motion systems; load firmware and software and apply the settings for each printer. 

• Validation (Level 700) — Run the full system test sequence to confirm the printer meets its acceptance criteria. 

• Final qualification (Level 800) — Support Test Engineering during final qualification and hand off each printer with all open items clearly documented. 

• Troubleshooting — Diagnose routine problems using wiring diagrams, piping diagrams and controller screens. Escalate anything outside the procedure to the lead technician or a Test Engineer, with symptoms, readings and steps already taken. 

• Records — Fill in test records accurately as you go, logging actual measurements, not just pass/fail. Report defects and suggest corrections where a procedure is unclear. 

• Safety — Follow lockout/tagout (isolating power before work), laser, compressed gas, high-voltage and metal powder safety rules without exception; keep the work area clean and audit-ready. 

Qualifications Required: 

• High school diploma or GED required; associate’s or bachelor’s degree in a technical field preferred. 

• 1–3 years hands-on testing, installing or servicing complex equipment — semiconductor, medical device, aerospace, industrial automation or military maintenance backgrounds all translate well. 

• Experience working to formal, revision-controlled procedures. 

• Comfortable with multimeters and basic test instruments; able to read wiring diagrams and work safely around high voltage. 

• Able to read piping diagrams; familiar with leak testing, precision assembly, torque specifications and alignment. 

• Comfortable with Windows and installing software; willing to learn firmware loading, controller interfaces and basic network troubleshooting. 

• Detail-oriented and disciplined — follows the procedure exactly and stops to ask rather than improvise. 

Preferred:

• Experience with compressed gas systems, closed-loop liquid cooling, high-voltage electrical, or laser systems (we will train). 

• Certifications, Working Conditions 

• Export control: must be ITAR-compliant (U.S. citizen or lawful permanent resident). 

• Laser safety, lockout/tagout, compressed gas, metal powder and forklift training provided and must be maintained. 

• Onsite at Fremont and Livermore. Day shift, with swing shift work as needed; a shift differential will be paid for swing shift hours. Occasional weekend work. 

• Exposure to high voltage, high-power lasers, inert gases, metal powders and noise; safety glasses, laser eyewear, steel-toed shoes and other PPE as posted. 

• Standing and walking for long periods, ladders and occasional confined spaces; lift up to 50 lbs; color vision and fine motor control required.
