Chief Mechanical Engineer

We’re hiring on behalf of Liquid Piston (LPI) — a cutting-edge company reinventing the internal combustion engine. Their patented rotary X-engine platform delivers ultra-efficient, compact, and power-dense engines for aerospace, defense, commercial, and mobility applications.

LPI is looking for a hands-on, strategic engineering leader to drive the development of their next-generation engine—from prototype to production.

As Chief Engineer, you’ll lead the technical execution of a major engine program. You’ll collaborate with cross-functional teams, oversee design and testing, and help shape the future of propulsion. This is a lab-driven, R&D-heavy role with high visibility and impact.

• Own the end-to-end development of a next-gen rotary engine
• Lead and grow a multidisciplinary engineering team
• Oversee engine design, integration, testing, and validation
• Partner with leadership to define the product roadmap
• Interface with customers, partners, and stakeholders
• Drive innovation in performance, manufacturability, and cost

• 10+ years leading engine or mechanical systems development
• Bachelor’s in Mechanical Engineering (Master’s or PhD preferred)
• Deep expertise in combustion engines, rotary systems, thermofluids
• Strong hands-on prototyping and lab-based engineering experience
• Skilled in CAD/simulation tools (Solid Works, FEA, etc.)
• Proven team leadership and cross-functional collaboration
