Sr. Principal Power Electronics Engineer at Nextpower · Trevo
Job Description
Senior Principal Power Electronics Engineer
Position Summary
We are seeking a Senior Principal Power Electronics Engineer to serve as a technical Subject Matter Expert (SME) for the development of advanced, grid-connected power conversion systems.
This is an expert hands-on individual-contributor role requiring deep technical expertise, strong engineering judgment, and the ability to influence complex cross-functional programs. The successful candidate will provide technical leadership across system requirements, magnetic component design, hardware architecture, validation, certification, and technology commercialization. The role does not include direct people-management responsibilities, but requires leadership through technical expertise, influence, mentoring, and cross-functional collaboration.
The role will work closely with global engineering teams and cross-functional partners to develop reliable, safe, manufacturable, and certifiable power conversion products.
What you'll do
Refine and manage system-level electrical requirements for advanced power conversion systems.
Provide technical leadership and expert guidance across power electronics architecture and design activities.
Lead the design, analysis, simulation, and optimization of coupled inductors and other magnetic components.
Participate in and provide technical leadership during schematic, PCB, and hardware design reviews.
Develop and review electrical, functional, environmental, reliability, and performance validation plans.
Analyze test results, identify root causes, and recommend design improvements or corrective actions.
Serve as a technical SME for Design for Certification, including UL, IEC, and other applicable standards and regulatory requirements.
Support the technical maturation of emerging power conversion technologies from research and development through product commercialization.
Collaborate with firmware, controls, mechanical, thermal, systems, test, manufacturing, quality, supply chain, and program management teams.
Provide technical direction and mentorship to engineers without assuming formal people-management responsibilities.
Evaluate technical risks, develop mitigation plans, and communicate status and recommendations to engineering and program leadership.
Support supplier and external-partner technical engagement, including design reviews, issue resolution, and technology evaluation.
Contribute to engineering processes, design methodologies, and technical standards that improve product quality and development efficiency.
Requirements
15+ years of experience in power electronics or power conversion product development.
Deep experience with high-power, grid-connected systems such as solar inverters, energy storage systems, industrial power supplies, motor drives, or related applications.
Strong understanding of power conversion topologies, magnetic components, switching devices, control interfaces, electrical insulation, and system-level design considerations.
Demonstrated experience designing or developing coupled inductors, transformers, reactors, or other high-power magnetic components.
Experience with electrical simulation and analysis tools for power electronics and magnetic components.
Experience leading or contributing to schematic, PCB, hardware, and system design reviews.
Demonstrated experience developing and executing comprehensive hardware validation and qualification plans.
Strong knowledge of product safety, certification, and regulatory requirements, including relevant UL and IEC standards.
Experience identifying certification requirements and integrating them into product design and development activities.
Experience with utility-scale or high-power three-phase power conversion systems.
Experience transitioning emerging technologies from R&D into production or commercial products.
Demonstrated ability to lead technically complex projects through influence and cross-functional collaboration.
Strong analytical, problem-solving, written, and verbal communication skills.
