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). ## Description As a Senior Test Engineer, you own how Velo3D proves its metal additive manufacturing printers are ready to ship and keeps them running. Every printer passes through three stages of test: * Subsystem bring-up (Level 600) - power up and verify each subsystem in turn: electrical and safety interlocks, argon gas and compressed air, cooling, motion, powder handling, laser optics, controls and software. * System validation (Level 700) - confirm the subsystems work together and the printer meets its acceptance criteria. * Final qualification (Level 800) - the last qualification checks and sign-off before a printer is released. You own the procedures for bring-up and validation, sign off final qualification, and keep our internal printers qualified and available. Test Technicians execute your procedures; you are their technical escalation point. Success looks like higher first-pass yield, shorter bring-up cycle time, failures caught in test rather than in the field, and recurring incidents closed with permanent fixes. 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., * Standing, ladders and occasional confined spaces; lift up to 50 lbs; occasional off-shift work for machine-down events
