System Integration Engineer

Our client, LiquidPiston is reinventing the internal combustion engine. Their patented X-engine architecture is a compact, lightweight, and fuel-efficient rotary engine that operates on a novel thermodynamic cycle. With applications in defense, aerospace, robotics, and portable power, we’re developing the next generation of high-performance, compact engines for critical power systems.

Position Overview:

They're seeking a Mechanical Integration Engineer as a part of the genset application development team to play a key role in the design, integration, and development of innovative gensets based on our advanced rotary engines. This is a hands-on, high-impact engineering role ideal for someone with a deep understanding of engine systems and packaging, a passion for innovation, and a strong background in mechanical design and simulation.

Key Responsibilities:

• Generate and evaluate new ideas to improve Packaging, durability, and manufacturability and reduce the weight of LiquidPiston’s rotary engine based gensets.
• Create detailed part and assembly models using SolidWorks.
• Lead early-stage genset architecture and layout processes.
• Perform component and system-level analysis using a combination of hand calculations, simulation tools, and experimental data.
• Create and release production-ready technical drawings.
• Work from requirements document to find appropriate components for assembly
• Aid senior engineers in developing requirements for new projects
• Work with electrical engineering team to package electrical systems into modules
• Select and coordinate with suppliers, contractors and machine shops—from RFQ to incoming inspection.
• Support and oversee the genset’s assembly processes; contribute to hands-on prototyping.
• Participate in genset testing and interpret results to inform design iterations.
• Create and maintain standardized procedures for system design, analysis, and documentation.
• Develop and implement subsystem test plans in conjunction with technicians.
• Present technical ideas and results clearly to both technical and non-technical stakeholders.
• Maintain a collaborative, proactive, and positive engineering mindset.

Qualifications:

• BS or higher in Mechanical Engineering
• 2+ years of experience in engine component/system design and simulation
• Experience in integrating multiple subsystems into a full package
• Strong understanding of internal combustion engine packaging and design for manufacturing.
• Proficient in SolidWorks (modeling and assemblies)
• Experience with mechanical simulation tools (e.g., ANSYS)
• Ability to work independently, solve problems, and communicate results effectively.

Preferred qualifications:

• Demonstrated previous experience in tight space packaging (engine bays, gensets etc.)
• Familiarity with packaging and integration of electrical components and design of electronic enclosures.
• Previous experience with design for MIL-STD-810 and MIL-STD-1472 conformity.
