Full Job Description

Mechanical Engineer
This role is fully onsite in Bloomfield, CT, five days per week, and the company will be relocating to Suffield, CT later in 2026.
About LiquidPiston:
LiquidPiston, Inc. is developing the next generation of compact, high-efficiency rotary engines based on its patented thermodynamic cycle. Our engines are being designed to transform power generation and propulsion across aerospace, defense, and commercial industries. We offer a fast-paced, hands-on R&D environment where mechanical engineers have a direct impact on shaping breakthrough technologies.
Position Overview:
We are seeking a hands-on, innovative Mechanical Engineer to join our dynamic team. In this role, you will contribute to all phases of engine development—from concept and design through testing and iteration—as we advance LiquidPiston’s rotary diesel engines toward production. This is a high-impact, cross-functional role requiring strong mechanical design skills, analytical thinking, and a passion for solving complex technical challenges.
Responsibilities:

Design, analyze, and develop engine components, subsystems, and custom test rigs
Use SolidWorks for 3D CAD modeling and drafting of engine parts and assemblies
Conduct engineering analysis using a combination of hand calculations, Matlab, custom code, and commercial simulation tools (e.g., GT-Suite)
Support prototype fabrication by working with in-house machinists and external vendors
Participate in the operation and testing of rotary engines on dynamometers and data acquisition systems
Assemble and disassemble prototype engines; perform part inspections and document build details
Troubleshoot and debug mechanical systems through hands-on work and root-cause analysis
Collaborate with cross-functional teams, technicians, and contractors to execute test and design projects
Present design proposals and test data clearly through reports, presentations, and team meetings
Help enforce engineering best practices and company policies (file organization, documentation, project management tools)
Stay current with advancements in rotary engines, diesel combustion, thermodynamics, and related technologies

Qualifications:

Bachelor’s degree in Mechanical Engineering or a closely related field
Proficiency in CAD design (SolidWorks preferred)
Familiarity with Matlab and mechanical system modeling/analysis
Solid understanding of mechanical fundamentals: thermodynamics, kinematics, stress analysis
Hands-on experience with mechanical systems—building, testing, or prototyping
Strong problem-solving skills, self-direction, and attention to detail
Excellent communication skills and ability to work in a collaborative team environment

Preferred Qualifications:

Experience with internal combustion engines, especially rotary or diesel platforms
Familiarity with GT-Suite or other engine simulation tools
Exposure to DAQ systems and test instrumentation
Experience managing prototype builds or working closely with machinists

Benefits:

Flexible PTO to encourage work-life balance and personal well-being
Comprehensive healthcare coverage: medical, dental, and vision plans
Equity participation: RSUs for all permanent employees
401(k) with match: 100% up to 3%, plus 50% match for 3–5% range
Growth opportunities: Mentorship, training, and leadership development

Our Culture
At LiquidPiston, we challenge convention and solve hard problems. We move fast, think boldly, and iterate quickly. Our team thrives on collaboration, creativity, and resilience. We take calculated risks and believe that every setback is a steppingstone toward breakthrough innovation.
Equal Opportunity Employer
LiquidPiston, Inc. is proud to be an Equal Opportunity Employer. All qualified applicants will receive consideration for employment regardless of race, color, religion, gender, sexual orientation, gender identity, national origin, or veteran status, and will not be discriminated against on the basis of disability.
