About the Role

The Enphase Power Systems Innovation team is seeking a Mechanical Design Engineer to define, prototype, and support Solid State Transformer products. This role involves owning the integration of the support and control system for Enphase's first-generation Solid State Transformer product, solving complex energy space problems, and shaping product direction.

Responsibilities

• Design high-current busbar assemblies, including conductor sizing, layout routing, thermal management, and mechanical mounting.
• Own wire harness design and routing, including connector selection, terminal specification, cable management, strain relief, and harness drawing packages.
• Design electronic board packaging solutions, including enclosures, mounting hardware, EMI shielding, thermal interface management, and serviceability provisions.
• Specify and design electrical connectors and interconnect systems, ensuring reliable mating, adequate current ratings, and compatibility with assembly and service workflows.
• Perform electrical insulation coordination for internal mechanical components, including creepage and clearance analysis, material selection for dielectric performance, and compliance with relevant voltage class requirements.
• Ensure field-replaceable boards are accessible and documented with clear service procedures.
• Ensure the design is manufacturable by selecting appropriate fabrication methods, tolerancing for producibility, and collaborating with contract manufacturing partners.
• Perform structural and thermal analysis (hand calculations and FEA/CFD) on busbars, mounting structures, and packaging assemblies.
• Produce 2D drawings and 3D CAD models, evaluate parts, and collaborate with stakeholders, suppliers, and contract manufacturing partners.
• Specify key functional and performance requirements; design and execute verification test plans.
• Complete documentation for design, testing, and analysis.
• Fabricate electromechanical assemblies and prototypes.
• Mentor junior staff.

Requirements

• Ability to solve problems independently and work effectively on early-stage product development efforts with ambiguous requirements and tasks.
• Ability to take ownership of development tasks and manage various high-importance tasks simultaneously.
• Significant experience in the mechanical design and integration of electrical support equipment for power electronics, power conversion, or analogous high-power electrical products.
• Strong proficiency in busbar design — conductor sizing, laminated busbar stack-ups, insulation systems, thermal rise calculations, and mechanical mounting methods.
• Demonstrated experience in wire harness design — routing, connector and terminal selection, wire gauge specification, and harness drawing creation.
• Experience designing mechanical packaging for electronic boards, including thermal management, shock and vibration isolation, EMI considerations, and board-level interconnects.
• Expertise in electrical insulation coordination — creepage and clearance analysis per IEC 60664-1 or equivalent, selection of insulating materials, and design practices for medium-voltage (>1 kV) environments.
• Strong understanding of connector systems for power and signal applications — contact ratings, environmental sealing, keying, and mating cycle durability.
• Demonstrated ability to design for manufacturing — tolerance analysis, process selection (sheet metal fabrication, CNC machining, injection molding, stamping, die casting), and close collaboration with manufacturing partners.
• Expertise in various joining techniques such as welding, adhesives, riveting, fastened joints, and press-fit connections.
• High proficiency with an enterprise CAD package (SolidWorks preferred).
• Good communication and documentation skills.
• Strong hands-on mechanical prototyping skills.

Skills

• SolidWorks
• FEA/CFD simulation (thermal, structural, electromagnetic)
• High-voltage (>1 kV) power conversion or switchgear equipment
• Common standards for electrical equipment (UL, IEC, NEMA, IEEE)
• Thermal management of power electronics assemblies (heat sink design, airflow path design, thermal interface materials, CFD)
• EMC/EMI design practices for power electronics packaging
• Laminated or flexible busbar design and fabrication
