Principal/Senior Electrical Engineer - Fuel Cell Systems Status: Exempt (Salaried) Department: Fuel Cell Platforms - Electrical Engineering Position Summary Plug is building the global hydrogen ecosystem. We are the only company delivering a complete hydrogen platform, from production and liquefaction to storage, delivery, and power generation. They are integrated, end-to-end solutions designed to make hydrogen work at an industrial scale across regions, industries, and applications. Plug is seeking a Principal or Senior Electrical Engineer to serve as the electrical technical authority for our hydrogen fuel cell power systems. This role sits at the intersection of high-power electronics, embedded controls, system architecture, and structured product development - spanning the full design lifecycle from concept through production release. You will lead electrical design decisions, drive verification and validation programs, partner with Supply Chain and Operations on design-for-manufacture readiness, and mentor engineers across the team. This position reports to the Manager of Electrical Engineering - Fuel Cells Platforms. Core Duties and Responsibilities Power Electronics & Converter Design Architect, design, and validate DC/DC power converters (LLC, phase-shift full bridge, interleaved boost, buck-boost) for fuel cell stack and BOP interfaces; define electrical specifications covering voltage/current profiles, efficiency, ripple, and EMI/EMC across all operating conditions Drive EMI/EMC mitigation from schematic through PCB layout and full system validation; design high-frequency magnetics for efficiency and manufacturability; own protection architecture, and SiC/GaN device selection Oversee schematic capture and PCB layout review (Altium preferred), component selection, and DFM; lead hardware design reviews (PDR, CDR) and resolve design issues through structured root cause and corrective action Controls & Embedded Systems Lead architecture, design, and validation of embedded control systems on DSP/MCU/FPGA platforms Define hardware-software interface requirements System-Level Electrical Architecture & Compliance Own the top-level electrical architecture for the fuel cell power system: power distribution, harness design, sensor integration, grounding strategy, and isolation/protection schemes Define balance-of-plant (BOP) electrical requirements for pumps, fans, valves, heaters, and auxiliary loads; specify thermal subsystem electrical requirements; partner with Mechanical and Thermal teams on integrated packaging and thermal management Lead compliance and certification activities for UL, CE, NFPA 2, SAE, and applicable ISO hydrogen and fuel cell standards; support regulatory approvals; Establish and own electrical FMEA and functional safety analyses Design Verification, Validation & Reliability Define and own the electrical Design Verification Plan and Report (DVP&R) aligned to industrial duty cycles, customer use cases, and applicable standards; lead DV and PV test execution through structured gate reviews Conduct environmental and safety qualification testing including shock, vibration, thermal cycling, freeze-thaw, and cold-start; lead accelerated stress and durability testing to identify failure modes and establish diagnostic parameters for predicting system lifespan Drive structured root cause and corrective action processes (8D, DMAIC) to resolve verification failures and field reliability issues; maintain and update DFMEA throughout the product development lifecycle to ensure risks are mitigated before production release Stage-Gate Program Execution Execute electrical development within Plug Power's stage-gate product development process, owning milestones: Concept Freeze, Design Freeze, DV/PV completion, Pilot Build, and Production Release Lead new product introductions (NPI) and major platform upgrades; ensure alignment of scope, schedule, technical readiness levels (TRL), and risk mitigation strategies; represent
