Endeavour has an exciting opportunity for someone passionate about sustainability and eager to be part of an innovative company that’s on a journey to transform the world’s infrastructure. 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.
We are highly selective because our mission demands it. We look for passionate changemakers who balance extreme talent with self-awareness and humility. In return, we offer a flexible, autonomous environment with endless opportunities for growth. Are you ready to #JoinTheJourney?
Key Responsibilities
Include 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 & Requirements
Education / 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.).
