Sr. Test Engineer

Responsibilities

• Procedures — Author, revise and release the bring-up (Level 600) and system validation (Level 700) procedures through engineering change control; set acceptance limits.

• Final qualification — Own Level 800 qualification and release sign-off; direct technician support and confirm printers arrive from system validation complete.

• Test equipment — Specify, build and validate test stations, fixtures and instrumentation; own gauge capability and calibration requirements.

• Internal fleet — Own incidents on internal printers to closure (ITRS, Splunk, Datadog); support software releases and user acceptance testing.

• Root cause — Lead root cause and permanent corrective action for test failures and recurring incidents with Hardware, Software, suppliers and Quality.

• Data and automation — Track yield, cycle time and downtime; write Shell/Python tooling to automate data capture, monitoring and repetitive steps.

• People and quality — Train Test Technicians on procedures, mentor junior engineers, and keep records to AS9100 standards.

Qualifications

• Bachelor’s in Electrical, Mechanical, Mechatronics or related engineering, or equivalent experience.

• 3–5 years in test, bring-up or manufacturing engineering on complex capital equipment (semiconductor, laser, medical, aerospace or automation).

• Has authored and released revision-controlled test procedures and led root cause to a verified fix.

• Hands-on across electrical (schematics, DMM, scope, megger), gas and fluid systems (P&IDs, leak-down), precision motion and optics.

• Controls and computing: firmware, PLC/controller interfaces, IP/Modbus networking, Linux/Windows, Shell and Python.

• Clear communicator who makes decisions from data and never skips a step under schedule pressure.




Preferred:

• Experience taking a new product from prototype into production test (new product introduction).

• Laser systems or metal additive manufacturing experience.

• Tracking equipment reliability and uptime — mean time between failures (MTBF) and mean time to repair (MTTR).

• Statistical process control (SPC) to monitor test results, and measurement system analysis (MSA) to prove test equipment is accurate and repeatable.

• Structured root cause methods such as 8D (eight-step problem solving) and 5-Why.

• Working in an aerospace or ISO quality system (AS9100 or ISO 9001).

Working Conditions

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

• Laser safety, LOTO, compressed gas and metal powder training provided and must be maintained.

• Onsite at Fremont and Livermore; exposure to high voltage, Class 4 lasers, inert gases, metal powders and noise; PPE as posted.

• Standing, ladders and occasional confined spaces; lift up to 50 lbs; occasional off-shift work for machine-down events
