Our mission is to deliver compact, fuel-efficient, high‑power‑density engines for a wide range of applications. We are seeking a highly motivated Senior Engineer – Performance & Calibration to help bring our advanced rotary engines to production.

Position Summary

As Senior Engineer – Performance & Calibration you will be a key contributor to engine performance development activities aimed at bringing LiquidPiston’s rotary engines to production. You will work closely within a team of Test Engineers, Technicians, and Performance Engineers as you develop engine calibration strategies and methodologies to meet performance targets. In addition, you will collaborate with Chief Engineers, Design Engineers, and other cross‑functional team members to help define critical data and insights needed to inform engine architecture and design decisions.

A broad range of experience and skills, along with the ability to adapt quickly from one task to another, will be essential for success. This role places strong emphasis on engine calibration supported by deep knowledge of engine performance, efficiency, testing, and data analysis. The position requires a solid foundation in thermal sciences and engineering principles, and the ability to work collaboratively with analysts using tools such as GT Power and combustion CFD platforms. You will also contribute to continuous improvement initiatives aimed at increasing the efficiency and effectiveness of simulation and development work.

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.

Requirements

• 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.

Beneficial

• Experience with simulation tools including GT Power, CONVERGE, and ANSYS Fluent.
• Familiarity with optimization methods, especially as applied to engine development and calibration.
