Engine Simulation Engineer
Location: Onsite in Bloomfield, CT
Join the Revolution in Engine Technology
At LiquidPiston, we’re redefining what’s possible in internal combustion. Our patented X-Engine architecture delivers a lighter, smaller, and more efficient solution compared to traditional engines — enabling new capabilities across aerospace, defense, and clean power generation. We’re not just building engines — we’re pushing the boundaries of innovation in power and propulsion. As part of our team, you’ll work alongside passionate engineers, designers, and researchers committed to solving hard problems and bringing cutting-edge technology to life. If you’re excited about clean-sheet engine design, real R&D challenges, and the opportunity to make a direct impact in a small, agile team — this is your chance to help build something truly revolutionary.
Responsibilities: Build and run 0D and 1D simulation models to analyze and predict engine behavior. Collaborate with our 3D CFD team to support holistic modeling approaches. Analyze simulation and experimental results to identify performance gaps and propose development strategies. Work closely with cross-functional design and test teams to drive engine improvements. Contribute to engine calibration and hands-on testing as needed. Develop and follow standardized simulation procedures specific to our unique rotary X-engine platform. Communicate findings clearly and effectively to stakeholders. Stay on the cutting edge of simulation tools and engine technology trends through self-directed learning and formal training. Requirements:
MS in Mechanical Engineering
(BS with significant relevant experience also considered). Strong grasp of thermodynamics, physics, and combustion engine efficiency principles. Professional experience correlating engine simulations with real-world testing. 3+ years of hands-on experience
using GT-Power or similar 1D engine simulation tools. Strong problem-solving skills and the ability to self-direct. Familiarity with DOE and optimization techniques. Benefits:
