About the role
The Enphase Power Systems Innovation team in the Office of the CTO is responsible for defining, prototyping, and supporting Enphase's Solid State Transformer (SST) products and next-generation power conversion platforms. The team is an integrated, multi-disciplinary group that moves fast, operates with high ownership, and delivers hardware from concept through field validation.
We are seeking a Senior Manager, Mechanical Engineering to lead and scale our mechanical engineering function. You are a technically strong Mechanical Engineer with a proven track record in product design, a passion for solving complex engineering challenges at pace, and demonstrated experience leading and developing engineering teams. You are technically proficient, a people leader, and capable of managing the scheduling and resourcing of a complex, multi-workstream hardware program.
What you will do
- Meet quarterly project progress targets, with goals that align with program milestones set by executive leadership.
- Lead professional development of your team — conduct performance reviews, support career growth, represent your team to the annual Performance Focal Group and Promotion Review Board.
- Own the mechanical architecture for SST racks, high-power enclosures, structural assemblies, power module packaging, busbar integration, and wiring harness routing. Drive designs from concept through detailed drawings, DFM review, and production release.
- Lead design options and reviews; drive optimization of electromechanical assemblies including EMI/EMC, thermal requirements, and electrical insulation coordination
- Apply DFM/DFA principles across the full product lifecycle, including supplier selection, process qualification, and tolerance analysis.
- Engage cross-functionally with power electronics, electrical hardware, firmware, systems, manufacturing, procurement, and quality teams to drive full-scope hardware delivery.
- Identify and resolve design requirement conflicts; ensure designs meet compliance requirements under UL, IEC, NEMA, and other applicable standards.
- Build and grow the mechanical engineering team — recruit, onboard, and develop top-tier mechanical engineers; establish team processes and a culture of engineering excellence and accountability.
- Present program status, technical risks, and design decisions clearly to senior leadership and cross-functional stakeholders.
Who you are and what you bring
- Bachelor's degree in Mechanical Engineering or a closely related discipline; Master's degree preferred.
- 12+ years of experience in mechanical product design and development, with a strong track record across the full product development lifecycle.
- Demonstrated experience leading and managing mechanical engineering teams of 4 or more engineers, including performance management and career development.
- Significant experience in the mechanical design and integration of electrical support equipment for power electronics, power conversion, or analogous high-power electrical products — including busbars, wire harnesses, electronic board packaging, and connectors.
- Demonstrable expertise in design and manufacturing processes: injection molding, sheet metal fabrication, CNC machining, and stamping/die casting.
- High proficiency with an enterprise CAD package — SolidWorks strongly preferred, ideally in a PDM/EPDM-managed environment.
- Experience with DFM/DFA principles and close collaboration with contract manufacturers and fabrication vendors.
- Experience with both investigative and verification testing — including writing test plans, executing tests, and authoring technical reports.
- Strong cross-functional communication skills — able to represent mechanical engineering clearly to electrical, firmware, systems, and executive stakeholders.
- Independent problem-solver who thrives in ambiguity and can navigate early-stage product development where requirements are still being written.
Additional desired skills
- Experience with medium-voltage power electronics packaging — creepage, clearance, and dielectric considerations for >1 kV environments.
- Experience with structural FEA for enclosure-level analysis: vibration, fatigue, seismic, and transportation loading.
- Exposure to Arena, Windchill, SolidWorks EPDM, or equivalent PLM/PDM systems.
Travel
Approximately 10–20% travel required to support prototype build events, supplier qualification visits, and product demonstrations. Domestic and occasional international travel.
Work location
Full-time onsite position based in Austin, TX.
The base pay range for this position is $130,000 to $183,000. This salary range may be modified in the future. The successful candidate’s starting pay will be determined based on job-related skills, experience, education or training, work location, and market conditions. This position is also eligible for bonus, equity, and benefits.
