Our breakthrough architecture enables highly modular and fully automated electrolyzers that scale to any size and optimize efficiency at all loads. We are on a mission to transition the global energy landscape towards a purely sustainable and emission free future.\nAbout the Role\nWe are looking for a full time Sr. Electrical Engineer to work on the design and development of high power electrical systems, from early ideation through architectural decisions, circuit implementation, and lab validation. You will own the design of power converters and their integration into our electrolyzer system, and play a hands-on role in bench-top bring-up, testing, and verification of your designs. You will also be responsible for setting up a lab for power electronics development and prototyping. The ideal candidate takes pride in delivering rigorous, well-documented designs and understands that clear electrical documentation and uncompromising safety practices are as critical as the designs themselves.\nRoles and Responsibilities\nExplore and develop novel ideas and architectural concepts for high power electrical systems (>100 kW, AC-DC), translating early ideation into concrete design decisions that guide system architecture and modularity.\n\nDrive the selection and validation of converter topologies against system-level design requirements - including input power quality, output current ripple, and efficiency - and own the bench-top testing and experimental validation that confirms or informs those architectural choices.\n\nDesign of power electronic converters, both AC-DC and DC-DC up to 50kW for integration into larger power systems.\n\nDevelop and maintain high quality Single Line Diagrams (SLDs) as a core design deliverable at each stage of the design process, from initial architecture through final system integration. SLDs must clearly communicate system topology, protection schemes, switching devices, and power flow to cross-functional stakeholders.\n\nProtection circuit design for current, voltage, and temperature.\n\nLow voltage design for current, temperature, voltage measurements, CAN/RS-485 communication interface\n\nDevelopment of Isolation and ground schemes\n\nDevelopment of Low voltage/on board power supply rails\n\nHigh power PCB design/layout experience with using Altium\n\nModeling and simulation of power circuits.\n\nSelection of all circuit components like MOSFET/IGBT, controllers, OP-amps & ADCs\n\nDefine converter control concept and complete small signal design and analysis.\n\nPower loss analysis.\n\nThermal design and analysis of the power components.\n\nPower quality design for 3 phase AC input (Power factor and total harmonic distortion).\n\nEnsure all designs comply with applicable electrical safety standards (e.g. UL, IEC, NFPA 70/NEC, IEEE) and actively participate in design reviews with a safety-first mindset.\n\nIdentify and document electrical hazards, develop mitigation strategies, and maintain design documentation sufficient to support third-party safety audits and certification processes.\n\nOversee procurement and assembly of hardware.\n\nLab bring-up and verification of initial design and revisions.\n\nSupport of the system integration and testing.\n\nWork independently and exercise judgment in making design changes.\n\nQualifications and Skills\nQualified candidates for this role will possess a Bachelor's Degree in Electrical Engineering with extensive industry experience bringing power circuit designs/products from concept to field deployment. A Masters degree in Electrical Engineering is a plus.\nOther Requirements\nKnowledge of power conversion circuits and topologies\nAC-DC: Totem pole PFC and 3 phase PFC, LLC\n\nDC-DC: Buck, Full bridge, PSFB, DAB, and LLC\n\nDemonstrated ability to produce clear, accurate, and complete Single Line Diagrams for high power systems, including proper representation of protective devices, grounding schemes, metering, and disconnects.\n\nWorking knowledge of electrical safety standards and regulatory frameworks relevant to high power industrial equipment, including UL 508A, IEC 62109, NFPA 70E, and/or NEC. Experience supporting UL/CE certification processes is strongly preferred.\n\nKnowledge and experience with LTspice, PLECS and Matlab Simulink.\n\nKnowledge and experience with schematic capture tools with preference for Altium.\n\nKnowledge and experience with printed circuit board design using popular CAD packages with a preference for Altium.\n\nKnowledge and experience mitigating EMI through circuit design and PCB layout.\n\nKnowledge of Matlab, Python, MathCAD and/or other common tools for design calculations.\n\nHands-on experience using lab equipment including soldering stations, oscilloscopes, power supplies, loads, network analyzers, data acquisition systems, and spectrum analyzers.\n\nDemonstrated safe laboratory practices and familiarity with arc flash analysis, lockout/tagout (LOTO) procedures, and high voltage safety protocols.\n\nStrong and effective verbal, written, and interpersonal communication skills.\n\nExperience designing high frequency magnetics is highly desirable.\n\nFamiliarity with Power Quality/EMI/EMC/Safety Regulatory Compliance is desirable.\n\nFirmware development for embedded controllers is desirable.\n\nWhat We Offer\nFully paid Medical, Dental, and Vision coverage\n\nCompetitive salary and equity compensation commensurate with experience\n\n401k\n\nDiverse and inclusive work environment\n\nA unique opportunity to influence a product concept at the highest level and then lead the delivery of key components\n\nPaid sick days and
