Test Technician

Velo3D•Fremont, CA

21d•$30 - $40•Onsite

About The Position

The Test Technician brings Velo3D metal additive manufacturing printers through subsystem bring-up, system validation, and final qualification. Working from written, step-by-step, revision-controlled procedures, the technician checks and tests newly assembled printers, identifies and escalates problems, and maintains complete records. Full training is provided. Once trained, the technician is expected to perform procedures independently while stopping and seeking help when an issue falls outside the procedure. The role includes pre-power electrical and configuration checks; sequential subsystem testing; pressure and leak checks; calibration of sensors, gauges, temperature controls, and motion systems; software and firmware installation and configuration; system validation against acceptance criteria; and support for final qualification and printer release. The technician troubleshoots routine issues using diagrams and controller screens, reports defects and unclear procedures, and records actual measurements and work performed. The position is onsite in Fremont and Livermore. It is primarily day shift, with swing-shift work as needed and occasional weekend work. Work involves exposure to high voltage, high-power lasers, inert gases, metal powders, and noise. Required PPE includes safety glasses, laser eyewear, steel-toed shoes, and other posted protective equipment. Physical demands include prolonged standing and walking, climbing ladders, occasional work in confined spaces, and lifting up to 50 pounds. Color vision and fine motor control are required. The position requires ITAR compliance (U.S. citizenship or lawful permanent residency).

Requirements

High school diploma or GED.
1–3 years of hands-on experience testing, installing, or servicing complex equipment.
Experience working to formal, revision-controlled procedures.
Comfort using multimeters and basic test instruments.
Ability to read wiring diagrams and work safely around high voltage.
Ability to read piping diagrams; familiarity with leak testing, precision assembly, torque specifications, and alignment.
Comfort with Windows and installing software, and willingness to learn firmware loading, controller interfaces, and basic network troubleshooting.
Detail-oriented and disciplined, with the ability to follow procedures exactly and stop to ask rather than improvise.
Must be ITAR-compliant: a U.S. citizen or lawful permanent resident.
Ability to perform the stated physical demands, including standing and walking for long periods, using ladders, occasional confined-space work, and lifting up to 50 pounds; color vision and fine motor control are required.

Nice To Haves

Associate’s or bachelor’s degree in a technical field.
Experience with compressed gas systems, closed-loop liquid cooling, high-voltage electrical systems, or laser systems.

Responsibilities

Perform pre-power checks, including wiring continuity, insulation, polarity, grounding, and printer configuration verification.
Bring up printer subsystems in sequence and verify electrical and safety interlocks, gas and compressed air, cooling, motion, powder handling, laser optics, controls, and software.
Perform pressure and leak checks on gas, vacuum, and coolant lines.
Calibrate sensors, gauges, temperature controls, and motion systems.
Load firmware and software and apply settings for each printer.
Run the full system validation sequence and confirm the printer meets acceptance criteria.
Support Test Engineering during final qualification and document open items when handing off each printer.
Diagnose routine problems using wiring and piping diagrams and controller screens; escalate issues beyond the procedure with symptoms, readings, and steps already taken.
Complete test records accurately, including actual measurements; report defects and suggest corrections where procedures are unclear.
Follow lockout/tagout, laser, compressed gas, high-voltage, and metal powder safety rules, and keep the work area clean and audit-ready.
Stop and ask for help rather than improvise when issues fall outside established procedures.
