We are seeking a
Senior Power Electronics Engineer to join a dedicated engineering team responsible for the design, simulation, and commercial release of high-power, grid-connected converters for utility-scale energy storage, data centers, and industrial electrification. This role requires technical breadth spanning device-level semiconductor physics (including switching and parasitics), circuit-level dynamics, and multi-megawatt system-level converter architectures. The team will own the core hardware design lifecycle, from topology selection and high-voltage magnetics design to physical prototyping, control loop integration, and certification.
The ideal candidate has a proven track record of transitioning power electronics from initial prototypes to high-volume mass production. Working in a collaborative team, you will partner with firmware/software, mechanical, thermal, manufacturing, compliance, certification, and reliability engineers to transition physical designs into robust, production-ready hardware platforms.
This role requires an agile, self-motivated professional who is comfortable navigating a fast-paced environment. You must be highly organized, an excellent communicator, and capable of operating with complete discretion.
Key ResponsibilitiesInclude but are not limited to:- Architectural design and detailed schematic implementation of advanced, bi-directional, isolated and non-isolated converter topologies (e.g., DAB, resonant topologies, multi-level converters MMCs, and multi-stage SSTs).
- Partner with mechanical and manufacturing engineers to integrate high-power converter modules and stacks with thermal management systems, racking, structural support, and system-level cabinet into manufacturable designs.
- Design layouts to minimize the critical effects of circuit parasitics - e.g. loop inductance, and gate loop parasitics, to manage voltage overshoot, ringing, and electromagnetic interference (EMI).
- Design custom, high-frequency, magnetic components, balancing core losses, skin/proximity copper losses, and thermal dissipation.
- Partner closely with embedded controls and firmware engineers to implement digital control algorithms.
- Lead hands-on bring-up, testing, debugging, and iterative hardware revisions of high-power modules, validating physical electrical circuit and thermal behavior against theoretical models.
- Implementation of state-of-the-art DFX practices throughout the hardware design cycle, including Design for Manufacturability (DFM), Design for Assembly (DFA), Design for Testability (DFT), and Design for Cost (DFC) to enable seamless, high-yield mass production.
- Collaborate closely with NPI and manufacturing engineers to establish robust production assembly flows, end-of-line functional testing configurations, and second-sourcing strategies for critical path components.
Skills & RequirementsEducation / Experience- MS or PhD degree with specialization in power electronics, plus industry experience (5+ years with MS and 3+ years with PhD) in developing high-power, high-voltage converters (kW to multi-MW scale).
- Mass Production & Commercial Release: A proven, referenceable track record of taking at least one complex, high-power electronics hardware product from early concept entirely through prototyping, regulatory certifications, and hand-off to sustained high-volume mass production.
- DFX: Expertise in modern Design for Excellence (DFX) principles. Demonstrated capability in identifying manufacturing bottlenecks, reducing Cost of Goods Sold (COGS), and improving product yield rates without sacrificing performance.
- Converter-Level Expertise: Proven track record of taking complex, high-power grid-tied converters from initial topology selection and multi-physics modeling through to a certified, physical commercial product.
- Semiconductor Switching Physics: Deep understanding of power semiconductor switching physics, device capacitance dynamics, wide bandgap semiconductors, safe operating area and thermal constraints.
- Parasitics & High-Frequency Circuit Dynamics: Expertise in identifying and mitigating parasitic layout, shielding methods, and high-frequency noise coupling paths in multi-layer PCBs, copper busbars, and power modules.
- Control of Power Converters: Familiarity with converter control, digital signal processing (DSP), and grid-connected inverter control methodologies (grid-following and grid-forming).
- Laboratory & Instrumentation: Expertise in high-power, high-voltage laboratory environments. Exceptional skill in utilizing oscilloscopes, differential probes, Rogowski coils, network analyzers, and power analyzers for dynamic signal characterization and switching loss extraction.
- Design & Simulation Tooling: Proficiency in schematic capture, multi-physics thermal/magnetic simulation, and circuit simulators (e.g., PLECS, SPICE, LTspice, Simulink).
Specific Skills / Abilities- Familiarity with modern PLM (Product Lifecycle Management) structures and enterprise PLM/CAD ecosystems (e.g., Dassault Systèmes / 3DEXPERIENCE / DSX environments) to manage bills of materials (BOMs), engineering change orders (ECOs), and multi-site production handoffs.
- Experience with medium-voltage (MV) systems and converters (e.g., 13-kV and 35-kV classes), including advanced insulation coordination, clearance/creepage design, and partial discharge mitigation.
- Experience with utility-scale grid-tied systems, including switchgear, circuit breakers, and protective relays.
- Familiarity with heavy industrial packaging technologies, structural busbars, specialized encapsulation potting, conformal coating, and liquid cooling architectures.
- Familiarity with evolving international power converter and grid codes (e.g., UL, IEEE, IEC, etc.).
