The Enphase Power Systems Innovation team in the office of the CTO is seeking a Mechanical Technician Temp for 2 months to support hands-on build-up, assembly, and integration of prototype solid-state transformer (SST) racks, skids, and enclosures. This is a full-time, 2 month temp position requiring on-site presence every day at our Austin, TX facility. Candidates must be local to the Austin metro area.

What You Will Do

• Rack and cabinet build-up—assemble electrical components, power supplies, contactors, breakers, fuses, terminal blocks, DIN rail hardware, and control devices onto 19-inch racks, NEMA cabinets, and prototype skids per engineering drawings and layouts
• Point-to-point wiring—route, terminate, label, and verify power and signal wiring per wiring diagrams, schematics, and wire lists; perform point-to-point continuity checks and ring-out before power-on
• Connector and terminal termination—crimp, solder, and terminate connectors including ring terminals, ferrules, Deutsch connectors, Anderson connectors, and multi-pin control connectors per manufacturer specifications
• Cable harness fabrication—build cable harnesses from cut sheets and harness drawings, including wire cutting, stripping, crimping, labeling, lacing, and strain relief installation
• Power distribution assembly—install and wire busbars, fuse holders, disconnect switches, power distribution blocks, and grounding systems per single-line diagrams and electrical schematics
• Instrumentation and sensor installation—mount and wire voltage transducers, current transformers (CTs), thermocouples, RTDs, pressure sensors, and other measurement devices
• Testing support—assist engineers with Hi-Pot, insulation resistance (Megger), functional checkout, and power-on commissioning of assembled systems; record test data and flag anomalies
• Labeling and documentation—apply wire labels, terminal markers, and component ID tags per labeling standards; maintain as-built redline drawings and build logs
• Safety and housekeeping—follow lockout/tagout (LOTO) procedures, maintain a clean and organized work area, and adhere to all EHS requirements for work on energized and de-energized electrical equipment

Who You Are and What You Bring

• Fundamental electrical knowledge — solid understanding of AC/DC circuits, Ohm’s law, series/parallel circuits, grounding, and electrical safety practices
• Education: Associate’s degree or technical certificate in Electrical Technology, Electronics, or related field; or equivalent military/trade training
• Experience: 2+ years of hands-on electrical assembly, wiring, or technician experience in a lab, manufacturing, or prototype environment
• Local to Austin, TX — must be able to report on-site daily for the full 3-month contract duration; this is not a remote or hybrid position

Minimum Skills, Knowledge, and Special Attributes

• Wiring and termination proficiency—demonstrated ability to read electrical schematics and wiring diagrams and translate them into correctly wired assemblies
• Hand tool and power tool proficiency—skilled with crimpers, wire strippers, torque wrenches, drill presses, band saws, and bench grinders
• Test equipment familiarity—comfortable using digital multimeters, Megger/insulation testers, clamp meters, and oscilloscopes at a basic level
• Mechanical aptitude—ability to drill, tap, mount components, and perform basic mechanical assembly tasks alongside electrical work
• Attention to detail—meticulous approach to wire routing, labeling, torque specs, and workmanship quality
• Self-starter with strong work ethic—ability to work independently once given clear direction, and proactively flag issues to the engineering team

Additional Desired Skills

• Medium- or high-voltage experience—hands-on work with systems above 480 VAC or 800 VDC
• IPC/WHMA-A-620 workmanship awareness—familiarity with cable and wire harness workmanship standards
• Power electronics exposure—prior experience in a power electronics, inverter, or energy storage lab environment
• PLC and controls wiring—experience wiring PLC I/O modules, relay logic panels, and industrial control systems

Physical Requirements & Working Conditions

• Ability to regularly lift, carry, push, and pull materials, components, and equipment weighing up to 50 pounds with assistance from another person or with appropriate material-handling equipment
• Ability to safely move and position large mechanical assemblies, racks, panels, transformers, heatsinks, and other prototype hardware
• Frequent standing, walking, bending, stooping, kneeling, crouching, reaching, and working in tight or confined spaces during assembly and integration activities
• Ability to use hand tools, power tools, measuring instruments, and shop equipment for extended periods of time
• Ability to climb ladders and work from step stools or elevated platforms as needed
• Ability to work in a laboratory, prototype, and light industrial environment with exposure to noise, dust, and varying temperatures
• Ability to wear required personal protective equipment (PPE), including safety glasses, gloves, hearing protection, and safety-toed footwear
• Ability to distinguish colors, read labels, assembly drawings, and technical documentation, and identify mechanical and electrical components
• Ability to operate or assist with material-handling equipment such as pallet jacks, hand trucks, chain hoists, and other lifting devices
• Ability to remain physically active throughout the workday and perform hands-on assembly, fabrication, and material-handling tasks on a daily basis

The hourly range for this position is $30-40/hr.
