Join our dynamic teams designing and developing next-gen energy technologies and help drive a sustainable future!

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.

The primary responsibility is assembling mechanical structures, mounting components onto racks and skids, and preparing prototype hardware for engineering test and evaluation. You will work under the direction of the engineering team, following assembly drawings, work instructions, and verbal guidance to deliver completed, test-ready assemblies.

What You Will Do

• Rack and skid assembly—assemble prototype racks, equipment skids, and enclosures from engineering drawings; mount power modules, transformers, capacitor banks, heatsinks, fans, and supporting hardware onto structural frames
• Component mounting and hardware installation—drill, tap, and fasten components using appropriate fasteners, standoffs, DIN rails, and mounting brackets per assembly drawings and torque specifications
• Sheet metal and structural fabrication support—perform basic cutting, bending, deburring, and fitting of sheet metal panels, brackets, and structural members using shop tools
• Heatsink and thermal system assembly—mount heatsinks, cold plates, fans, ducting, and thermal interface materials per engineering specifications; ensure proper contact pressure and alignment
• Busbar and conductor installation—install pre-fabricated busbars, power conductors, and grounding straps per assembly drawings; perform basic bending, drilling, and insulation wrapping as needed
• Fit checks and prototype iteration—identify fit, interference, and assembly issues during builds; communicate findings to engineers and implement hands-on fixes to keep builds moving
• Receiving and inventory support—receive prototype parts and materials, verify against packing lists and purchase orders, organize and stage parts for assembly
• Test fixture fabrication—build mechanical test fixtures, jigs, and support structures for prototype testing including vibration, thermal, and environmental test setups
• Documentation and as-built records—maintain build logs, mark up assembly drawings with as-built conditions, take build photos, and record deviations from design
• Safety and housekeeping—follow all EHS procedures, maintain a clean and organized lab and shop area, and use appropriate PPE for all fabrication and assembly tasks

Who You Are and What You Bring

• Fundamental mechanical knowledge — solid understanding of mechanical fasteners, torque specifications, tolerances, fits, and basic structural concepts
• Fundamental electrical knowledge — comfortable working around electrical systems; understanding of basic electrical safety, grounding, and lockout/tagout procedures
• Education: Associate’s degree or technical certificate in Mechanical Technology, Industrial Maintenance, Manufacturing Technology, or related field; or equivalent military/trade training
• Experience: 2+ years of hands-on mechanical assembly, fabrication, 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 temp duration; this is not a remote or hybrid position

Minimum Skills, Knowledge, and Special Attributes

• Mechanical assembly proficiency—demonstrated ability to read mechanical assembly drawings, exploded views, and BOMs, and translate them into correctly assembled hardware
• Hand and power tool proficiency—skilled with torque wrenches, impact drivers, drill presses, band saws, grinders, taps and dies, and basic shop equipment
• Measurement and inspection—proficient with calipers, micrometers, tape measures, levels, and squares; ability to verify dimensions against drawings
• Material handling—experience operating pallet jacks, hand trucks, and hoists for moving heavy components safely; forklift certification a plus
• Basic electrical aptitude—ability to use a multimeter, identify wire gauges, and perform simple electrical tasks such as grounding strap installation and sensor mounting
• Attention to detail—meticulous approach to torque specs, hardware selection, alignment, 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

• Power electronics or energy equipment experience—prior experience assembling inverters, transformers, switchgear, or similar power conversion equipment
• Welding and metal joining—MIG/TIG welding certification or hands-on welding experience
• CAD literacy—ability to navigate 3D models in SolidWorks, STEP viewer, or eDrawings to understand assembly intent
• Rigging and heavy equipment handling—experience with overhead cranes, gantry cranes, chain hoists, and machinery skates for moving heavy assemblies
• Forklift certified—current forklift operator certification for cushion or pneumatic tire forklifts

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.
