Built around a patented rotary engine architecture, LiquidPiston is challenging conventional approaches to propulsion by developing smaller, lighter, more powerful, and more fuel-efficient systems. This is an opportunity to work on a fundamentally different engine architecture and solve controls challenges that don't have a textbook answer.\n\nPosition Summary:\nLiquidPiston is seeking a Controls Engineer to design, develop, troubleshoot, and improve the control systems that operate our next-generation rotary engines and power systems. This is a hands-on engineering role for someone who enjoys working on innovative technologies, understanding how a system behaves, identifying why it isn't working as expected, and developing practical solutions. You won't simply be tuning tables or working within a narrowly defined controls function. You'll work across the engine, genset, instrumentation, firmware, and test environment to understand problems at the system level and help drive them to resolution.\nThe Controls Engineer will work closely with mechanical engineers, engine performance engineers, technicians, and test engineers to develop and improve control strategies, implement firmware changes, analyze test data, and troubleshoot issues on real hardware.\nThe ideal candidate is curious, analytical, and comfortable getting into the details. You should be someone who can take a controls problem from “something isn't working” to understanding the root cause, developing a solution, implementing it, and validating the result.\n\nThe Opportunity:\nThis isn't a role where you'll spend your days maintaining an established controls system. You'll be helping develop the controls that make a new generation of rotary engines and power systems work. You'll have the opportunity to work directly with engineers and technicians, get onto the test floor, diagnose real problems, write and modify control logic, and see the results of your work on running hardware. The systems are complex, the problems are challenging, and there is plenty of room to learn and make an impact. For an engineer who enjoys figuring out why something isn't working, digging into the data, and then getting hands-on to make it work, this role offers the chance to have a direct impact on technology that is being developed from the ground up.\n\nResponsibilities:\nDevelop, implement, and troubleshoot control strategies for LiquidPiston engines, gensets, and associated power systems.\nDevelop and modify embedded control software and firmware for engine and power system applications.\nWork with engine, electrical, mechanical, and test engineers to define and implement control requirements.\nAnalyze engine and system behavior using test data, instrumentation, and control-system diagnostics.\nTroubleshoot controls issues on test hardware and identify root causes rather than simply addressing symptoms.\nDevelop control logic for engine operation, including starting, speed control, load management, protection, and shutdown strategies.\nSupport integration of sensors, actuators, ECUs, and other control-system hardware.\nDevelop and improve control algorithms and state machines.\nParticipate in engine and genset testing and support troubleshooting directly in the test environment.\nWork with technicians and test engineers to reproduce and diagnose controls-related problems.\nImplement firmware updates and validate changes through testing.\nSupport calibration and optimization of control parameters as part of broader system development.\nDocument control strategies, software changes, test results, and engineering decisions.\nHelp establish and improve controls development, testing, and troubleshooting processes.\nContribute to the development of next-generation propulsion and power-generation platforms.\n\nQualifications:\nRequired skills:\nBachelor's degree in Electrical Engineering, Controls Engineering, Computer Engineering, Mechanical Engineering, or a related technical field.\n3+ years of experience in controls engineering, embedded systems, engine controls, automotive controls, aerospace controls, robotics, or a related field.\nExperience developing or modifying embedded control software.\nStrong understanding of control systems and feedback control concepts.\nExperience working with sensors, actuators, ECUs, or similar control hardware.\nExperience troubleshooting controls issues using test data and system-level diagnostics.\nAbility to read and understand electrical schematics and system-level diagrams.\nExperience working directly with physical hardware and test equipment.\nStrong analytical and problem-solving skills.\nAbility to work effectively in a fast-paced, hands-on R&D environment.\nPreferred skills:\nExperience with engine controls, powertrain controls, gensets, or other power-generation systems.\nExperience with MATLAB/Simulink or similar modeling and controls-development tools.\nExperience with embedded C/C++.\nExperience with CAN/CANbus and related communication protocols.\nExperience with Motec or similar engine control systems.\nExperience with calibration and engine testing.\nFamiliarity with data acquisition systems and test instrumentation.\nExperience troubleshooting control systems on physical hardware.\nUnderstanding of internal combustion engines and engine operating principles.\nExperience working in aerospace, defense, automotive, motorsports, or other high-performance engineering environments.\n\nBenefits & Perks:\nPTO: 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.\nEquity Participation: Employes may receive RSUs (Restricted Stock Units).\n401(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 Culture:\nAt 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. Qualified applicants will not be discriminated against, and receive consideration for employment without regard to race, color, religion, gender, sexual orientation, gender identity, national origin, or protected veteran status or disability.\nAll offers of employment at LiquidPiston are contingent upon successful completion of a pre-employment background check and drug screening.\nB0w6AtfMRS","company":"Liquidpiston","rawCompany":"liquidpiston","city":"West Suffield","state":"CT","isRemote":false,"isActive":false,"createdAt":"2026-08-06T09:44:50.923Z","occupations":[{"code":"17-2199.05","title":"Mechatronics Engineers","slug":"mechatronics-engineers"},{"code":"17-2199.00","title":"Engineers, All Other","slug":"engineers-all-other"},{"code":"17-2141.00","title":"Mechanical Engineers","slug":"mechanical-engineers"}],"industries":[{"code":"541330","title":"Engineering Services","slug":"engineering-services"},{"code":"333618","title":"Other Engine Equipment Manufacturing","slug":"other-engine-equipment-manufacturing"},{"code":"335314","title":"Relay and Industrial Control Manufacturing","slug":"relay-and-industrial-control-manufacturing"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Controls Engineer","description":"Controls Engineer – LiquidPiston\nLocation: Bloomfield, CT | Fully onsite, 5 days per week\nLiquidPiston is currently located in Bloomfield, CT and will be relocating to Suffield, CT later in 2026.\n\nAbout LiquidPiston:\nLiquidPiston is an advanced propulsion technology company developing compact, high-efficiency engine and power system solutions for aerospace, defense, and commercial applications.
