Senior Performance Engineer

Our client, LiquidPiston is an advanced engine development company focused on revolutionizing internal combustion technology through its innovative rotary engine design. By rethinking traditional engine architecture, LiquidPiston is developing compact, efficient, and high power-density engines for a wide range of applications. The team operates in a fast-paced, engineering-driven environment focused on innovation, collaboration, and bringing cutting-edge technology to production.Role Overview:As a Senior Engine Performance Engineer, you will play a key role in advancing the development of LiquidPiston’s rotary engines toward production. Working closely with Chief Engineers, Design Engineers, and cross-functional teams, you will help define the data needed to guide engine architecture, design features, and calibration strategies. You will develop and execute test and analysis plans in collaboration with Test and Simulation Engineers, while occasionally performing high-level analyses or basic GT-Power simulations to support decision-making.This role is heavily focused on data analysis and insight generation. You will review and interpret large datasets, draw conclusions, and make data-driven recommendations to stakeholders through presentations and detailed technical reports. You will also collaborate with Modeling and Simulation teams to integrate analytical results into your recommendations, while contributing to continuous improvement efforts that enhance the efficiency and effectiveness of engine performance development.Key Responsibilities:Develop a deep understanding of the data required to inform engine architecture, design features, and calibration strategies that meet performance goalsPartner with Test Engineers to create and execute test plans that generate critical experimental dataCollaborate with Modeling and Simulation Engineers to define and execute simulation plans. Review analytical outputs and incorporate insights into recommendationsPerform rough order-of-magnitude analyses and basic GT-Power simulations as neededTake ownership of the quality and reliability of test and analysis results, including understanding assumptions and uncertaintiesAnalyze experimental data in detail and present findings, recommendations, and supporting evidence to stakeholdersPrepare comprehensive technical reports documenting test objectives, results, conclusions, and next stepsApply sound engineering judgment to balance aggressive timelines with risk and uncertaintyContribute to continuous improvement initiatives to enhance performance development processesEnsure compliance with safety standards and regulatory requirementsFollow company policies related to data management, time reporting, IP protection, and complianceCommunicate clearly and professionally with cross-functional teamsDemonstrate ownership, maintain a positive and open-minded attitude, and adapt effectively to challenges and setbacksRequirements:Bachelor’s degree in Mechanical Engineering or a related field (Master’s preferred)5+ years of experience in engine performance development, testing, or calibrationStrong understanding of internal combustion engines (rotary engine experience is a plus)Experience developing and executing engine test plans and analyzing performance dataFamiliarity with engine simulation tools such as GT-Power (or similar)Hands-on experience with engine testing equipment and measurement toolsStrong analytical and problem-solving skills with the ability to interpret complex datasetsExperience working in cross-functional engineering teams, including test and simulationAbility to clearly communicate technical findings to both technical and non-technical stakeholdersExperience in an R&D or prototype environment is highly preferredSelf-starter with strong attention to detail and a proactive, ownership-driven mindsetIf interested apply here or LiquidPiston Apply Here
