Engineering Technician

The role

This person will build, wire, and assemble prototype electromechanical systems and run development tests. The role involves working between the shop floor and test environment to support next-generation energy hardware.

What you will do

• Build, wire, and assemble prototype electromechanical skids, control cabinets, switchgear, and subassemblies from drawings and instructions.
• Perform HV/LV wire routing, harnessing, crimping, terminations, connector installation, fastening, and torquing.
• Set up and operate bench and hardware-in-the-loop (HIL) test equipment.
• Execute development and validation testing and capture test data.
• Read and interpret electrical drawings, wiring diagrams, mechanical drawings, GD&T, BOMs, and work instructions.
• Identify build and test issues and troubleshoot problems with engineering.
• Verify and redline drawings and work instructions.
• Document nonconformances and provide feedback for designs and processes.
• Maintain organized lab tools and instrumentation and ensure calibration is current.
• Follow established safety practices for high-voltage and high-energy systems.

Required qualifications

• 5+ years of experience as an Engineering Technician, Test Technician, Electromechanical Technician, Prototype Technician, Integration Technician, or similar hands-on technical role.
• Experience building and/or testing precision electromechanical hardware to print in industries such as energy/BESS, EV/battery, automotive, aerospace, or industrial hardware.
• Strong ability to independently read and build from engineering drawings, electrical schematics, wiring diagrams, GD&T, BOMs, and work instructions.
• Hands-on experience with precision assembly and electrical harnessing, including torque specifications, crimps, terminations, connectors, routing, labeling, and fasteners.
• Experience setting up test instrumentation and collecting reliable, traceable data using equipment such as DAQ systems, sensors, oscilloscopes, power analyzers, and load banks.
• Working knowledge of electrical safety practices, including LOTO and appropriate PPE when working around high-voltage or high-energy equipment.
• Ability to work on-site in Long Beach/Torrance.
• Ability to lift approximately 50 lbs.

Nice to have

• Experience working within a formal quality system such as AS9100 or IATF 16949, including FAI, traceability, nonconformance documentation, ECOs, and redlines.
• IPC/WHMA-A-620 or J-STD-001 experience or certification.
• Soldering and electrical rework experience.
• Experience with battery energy storage systems, EV battery/powertrain systems, aerospace hardware, or other high-power electromechanical systems.
• Basic comfort working with test data in Python or spreadsheets.
• Valid California driver's license.

Benefits

• Equity ownership through stock options
• Comprehensive health coverage (medical, dental, and vision) through an HRA with a generous allowance
• Retirement savings plan
• Unlimited paid time off
