Engine Performance Engineer

About the role

This role is fully onsite in Bloomfield, CT, five days per week, and the company will be relocating to Suffield, CT later in 2026.

Responsibilities

• Perform engine calibration to meet targets for power, efficiency, emissions, transient response, and off-nominal operating conditions.
• Develop efficient processes and methods for engine calibration tailored to the rotary X-engine platform.
• Document and communicate results of calibration efforts clearly and effectively.
• Design and execute engine test plans for performance development, including analysis and reporting of results.
• Collaborate with analysts running GT Power, combustion CFD, or other simulation tools to support holistic, model-based development approaches.
• Work closely with cross-functional design and test teams to drive engine improvements and support design decisions.
• Develop and follow standardized test and calibration procedures specific to LiquidPiston’s engine architecture.
• Contribute to continuous improvement efforts that enhance testing efficiency, simulation accuracy, and overall development effectiveness.
• Stay current with emerging engine technologies, calibration strategies, and simulation tools through self-directed learning and formal training.

Qualifications

• PhD or MS in Mechanical Engineering (BS with significant relevant experience will also be considered).
• Strong grasp of thermodynamics, physics, combustion, and engine efficiency principles.
• Demonstrated engine testing and calibration experience.
• Proficiency with MATLAB, CAN communication tools, Python, or other scripting languages.
• Strong problem-solving and analytical skills.
• Strong team player with the ability to be self-directed in a fast-paced development environment.
• Experience with simulation tools including GT Power, CONVERGE, and ANSYS Fluent.
• Familiarity with optimization methods, especially as applied to engine development and calibration.
