Mechanical Engineer I in Bloomfield, Connecticut at LIQUIDPISTON, INC.

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
