Skunkwerks Engineer

About the role

LiquidPiston, Inc. is a technology startup reinventing the internal combustion engine based on a patented thermodynamic cycle and novel rotary architecture. Our compact, high-efficiency engines power applications across defense, aerospace, and commercial sectors. At LiquidPiston, you’ll be part of a passionate team pushing the boundaries of what's possible in propulsion technology.

Responsibilities

• Design key engine components including pistons, rods, crankshafts, rotors, and housings.
• Develop CAD models and engineering drawings using SolidWorks (preferred) or similar tools.
• Conduct structural and thermal Finite Element Analysis (FEA) to evaluate component integrity.
• Support prototype builds by collaborating with assembly technicians and manufacturing partners.
• Apply best practices in engine assembly processes and documentation.
• Participate in design reviews, failure analysis, and test result interpretation.
• Integrate feedback from testing and validation into iterative design improvements.
• Ensure alignment with DFM/DFA principles for smooth transition to production.
• Cook with cross-functional teams (manufacturing, testing, controls, and quality) to achieve performance goals and meet development timelines.

Requirements

• Bachelor’s, Master’s, or Ph.D. in Mechanical Engineering or a related field.
• Expert with demonstrated ability to conduct advanced CFD simulations for combustion, flow, and thermal analysis.
• Proficiency with CAD software (SolidWorks preferred; CATIA, NX, or similar acceptable).
• Experience with engine prototype development and validation practices.
• Familiarity with engine assembly techniques and processes.
• Strong knowledge of design for manufacturability (DFM) and design for assembly (DFA).
• Understanding of engine design standards and best practices.
• Proven ability to work in cross-functional teams and manage multiple projects simultaneously.
• Familiarity with machining processes and manufacturing requirements.
• Proficient in Geometric Dimensioning and Tolerancing (GD&T) and metrology tools.
• Good foundation in materials science and selection for high-performance engine parts.
• Knowledge of vibration analysis and NVH (noise, vibration, harshness) principles.
• Experience in lubrication system design, oil flow, and bearing analysis.
• Understanding of cooling system design and thermal management principles.
• Exposure to intake and exhaust system design.
• Experience with engine dynamometer testing and data interpretation.
