Mechanical Design Engineer — Austin, TX (Temp Local Candidates Only)

About the Role

The Enphase Power Systems Innovation team in the office of the CTO is responsible for defining prototyping and supporting Enphases Solid State Transformer product line. We are seeking a temporary Mechanical Design Engineer (Senior or Staff level) to build and iterate on prototype systems for medium-voltage power conversion platforms including solid-state transformers (SSTs) and associated enclosure and skid-level packaging. The temp position will be required to be onsite in our Austin TX location.

This is a hands-on prototyping design and execution role. The contractor will translate engineers design concepts into physical prototype assemblies working under the direction of the mechanical engineering lead. The primary focus is building assembling and iterating on prototype hardwarenot originating design concepts. This is a contractor position not a full-time employment offer.

What You Will Do

• Build and assemble prototype systems from engineers design conceptstranslate sketches 3D models and specifications into physical hardware delivering assembled prototype units ready for test
• Hands-on fabrication assembly and reworkwork directly on electromechanical prototype assemblies including enclosures busbars heatsinks wiring harnesses and mounting structures
• Rapid prototype iterationidentify fit and assembly issues during builds propose practical fixes and implement changes on the bench to keep development moving
• Execute engineers design ideas end-to-endsource parts coordinate with vendors fabricate components and deliver completed assemblies on schedule
• Vendor and shop interfacework with sheet metal vendors machine shops and contract manufacturers to procure prototype parts on tight timelines
• Wire harness buildsconnector termination cable routing strain relief labeling and point-to-point verification per harness drawings
• Busbar fabricationcutting bending drilling insulating and installing busbar assemblies per engineering drawings
• Test fixture design and buildcreate fixtures for Hi-Pot partial discharge corona vibration and ingress protection testing
• CAD support for prototype buildscreate and modify 3D models and detailed manufacturing drawings (SolidWorks preferred) as needed to support fabrication
• BOM and parts trackinggenerate BOMs track prototype parts and coordinate with supply chain for component specifications and vendor drawings
• Documentationcomplete as-built records build logs test reports and design file maintenance in the company PDM/PLM system

Who You Are and What You Bring

• A demonstrated track record of excellence in hands-on prototype building and mechanical fabrication
• BS/MS Mechanical Engineering or closely related discipline
• Experience: Senior (5 years) or Staff (10 years) of hands-on mechanical design and prototyping in power electronics power conversion or analogous high-power electrical products
• Minimum Skills Knowledge and Special Attributes
• Prototype builder at heartyou are as comfortable on the shop floor building assemblies as you are behind a screen reviewing drawings; hands-on fabrication is your primary mode of work
• Independent problem solverability to work effectively on early-stage product development efforts with ambiguous requirements and tasks
• Electromechanical assembly expertisesignificant experience building and integrating electrical support equipment for power electronics power conversion or analogous high-power electrical products
• Busbar fabrication proficiencyhands-on experience with conductor sizing laminated busbar stack-ups insulation systems and mechanical mounting methods
• Wire harness build experiencerouting connector and terminal crimping wire gauge selection and point-to-point verification
• Mechanical packaging for electronicsexperience assembling packaging for electronic boards including shock and vibration isolation EMI shielding and board-level interconnects
• Connector systems knowledgepower and signal connectors contact ratings environmental sealing keying and mating cycle durability
• Manufacturing-savvy builderyou understand sheet metal fabrication CNC machining injection molding stamping and die casting well enough to flag issues and work effectively with manufacturing partners
