The company will be relocating to Suffield, CT later in 2026.\nAbout LiquidPiston\nLiquidPiston is revolutionizing combustion engine technology through the development of advanced rotary engines and integrated hybrid power systems. Our innovative designs aim to dramatically improve efficiency, reduce size and weight, and enable cleaner, more compact power solutions across defense, aerospace, and commercial sectors.\nPosition Overview\nThis role is ideal for someone who enjoys owning hardware from concept through production. While power electronics is a major part of the job, this is not a narrowly scoped “design one converter for a year” role. The right candidate is excited by the broader challenge of building reliable, high-performance products in a small-company environment where priorities evolve quickly and engineers wear multiple hats.\nKey Responsibilities\nDesign, simulate, prototype, debug, and improve power electronics hardware for advanced engine and generator systems\nDevelop and support converters, inverters, motor drives, power distribution systems, battery interfaces, and related hardware\nPerform hands-on hardware bring-up, troubleshooting, validation, rework, and root-cause analysis of electrical and thermal failures\nAddress real-world hardware challenges including EMI/EMC issues, component failures, manufacturability concerns, and reliability improvements\nWork closely with electrical, mechanical, embedded controls, and test engineers to develop fully integrated products\nOversee external vendors and contractors, including reviewing designs, identifying issues, and resolving integration or quality problems\nExecute rapid prototype development, bench testing, and in-house troubleshooting to support development timelines\nContribute to related electrical engineering efforts beyond core PE, including engine controls, genset controls, instrumentation, wiring, and general EE tasks\nSupport iterative product development and continuous improvement activities throughout the product lifecycle\nOperate effectively in a fast-paced small-company environment where priorities may shift and engineers are expected to take broad ownership\nRequired QualificationsBS or MS in Electrical Engineering or related field\nStrong hands-on experience designing and developing power electronics hardware\nExperience with converters, inverters, motor drives, high-current/high-voltage systems, or related power electronics applications\nPractical experience with hardware debugging, lab testing, prototype integration, and failure analysis\nStrong understanding of real-world electrical engineering tradeoffs including thermal management, PCB layout, EMI/EMC, reliability, and manufacturability\nExperience working with external vendors, contract manufacturers, or third-party design firms\nComfortable performing hands-on lab work including soldering, rework, instrumentation, and troubleshooting\nAbility to work across disciplines and contribute to broader electrical and system-level engineering challenges\nAdaptable, self-motivated, and comfortable working in a highly collaborative small-team environment\nStrong problem-solving skills and a demonstrated ability to drive hardware issues to resolution quickly and effectively\nPassion for building and improving real-world hardware products\n Preferred QualificationsExperience with weight- and efficiency-critical designs (e.g., aerospace, defense, UAVs).\nBackground in hybrid power systems, gensets, and MIL-STD compliant systems (e.g., AMMPS).\nKnowledge of CANBUS/MODBUS communication protocols.\nHands-on experience with PCB layout and design tools such as Altium or OrCAD.\nFirmware development experience (C/C++ preferred).\nProject management skills with experience coordinating across teams and with external stakeholders.\nBenefits & PerksPTO: We value work-life balance and encourage time to rest and recharge. \nHealth & Wellness: Comprehensive medical and voluntary dental, and vision coverage - you choose what works best for you.\n Equity Participation: Employes may receive RSUs (Restricted Stock Units).\n 401(k) Match: We offer a 401k w/100% matching up to 3% of your salary and then 50% of contributions between 3-5% after 1 year of employment. \nCareer Growth: Ongoing training, mentorship, and learning opportunities to accelerate your growth.\nOur CultureAt LiquidPiston, we embrace challenges, move fast, and celebrate curiosity. Our team thrives on collaboration, creativity, and perseverance. We understand that innovation involves risk - and we’re not afraid to fail as we move forward.\nEqual Opportunity Employer\nLiquidPiston, Inc. is proud to be an Equal Opportunity Employer.
