What is the difference between Engine Performance Simulation Engineer vs Powertrain Engineer?

AspectEngine Performance Simulation EngineerPowertrain Engineer
Primary FocusModeling and simulating engine performance and efficiencyDesigning and optimizing entire powertrain systems, including engine, transmission, and drivetrain
Required SkillsEngine simulation software, thermodynamics, engine mechanicsPowertrain integration, system-level analysis, control systems
Work EnvironmentR&D labs, simulation software environmentsDesign studios, testing facilities, cross-disciplinary teams
Industry UsageAutomotive, aerospace, heavy machineryAutomotive, commercial vehicles, hybrid/electric vehicle development

The Engine Performance Simulation Engineer specializes in creating detailed models to analyze engine behavior, while the Powertrain Engineer focuses on designing and integrating all components of the vehicle's power delivery system. Both roles require strong technical skills, but their scope and focus differ, with the simulation engineer concentrating on engine specifics and the powertrain engineer overseeing broader system integration.

What are the key skills and qualifications needed to thrive as an Engine Performance Simulation Engineer, and why are they important?

To thrive as an Engine Performance Simulation Engineer, you need a solid background in mechanical or automotive engineering, strong analytical skills, and experience with thermodynamics and fluid mechanics. Proficiency with simulation software such as GT-Power, MATLAB/Simulink, and CAD tools, along with knowledge of engine modeling methodologies, is typically required. Outstanding problem-solving abilities, attention to detail, and effective teamwork and communication skills set top performers apart. These skills and qualities are crucial for accurately predicting engine performance, optimizing designs, and collaborating efficiently in multidisciplinary engineering teams.

What are some common challenges faced by Engine Performance Simulation Engineers during project development?

Engine Performance Simulation Engineers often encounter challenges such as accurately modeling complex engine behaviors, managing large volumes of simulation data, and ensuring that simulation results align with real-world test data. Collaborating closely with design, testing, and calibration teams is essential to interpret results and refine simulation models. Additionally, keeping up with rapidly evolving simulation tools and integrating them into existing workflows can be demanding. Overcoming these challenges requires strong analytical skills, attention to detail, and effective communication with multidisciplinary teams.

What does an Engine Performance Simulation Engineer do?

An Engine Performance Simulation Engineer is responsible for using advanced software tools to model, analyze, and predict the performance of internal combustion engines or alternative powertrains. They simulate how engines will operate under various conditions, optimize engine parameters for efficiency and emissions, and support the design process before physical prototypes are built. Their work helps manufacturers create engines that meet performance, fuel economy, and regulatory requirements more efficiently and cost-effectively.

Job description

Senior Engine Performance Engineer
This role is fully onsite in Bloomfield, CT, five days per week, and the company will be relocating to Suffield, CT later in 2026.
About LiquidPiston:
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 goals
  • Partner with Test Engineers to create and execute test plans that generate critical experimental data
  • Collaborate with Modeling and Simulation Engineers to define and execute simulation plans. Review analytical outputs and incorporate insights into recommendations
  • Perform rough order-of-magnitude analyses and basic GT-Power simulations as needed
  • Take ownership of the quality and reliability of test and analysis results, including understanding assumptions and uncertainties
  • Analyze experimental data in detail and present findings, recommendations, and supporting evidence to stakeholders
  • Prepare comprehensive technical reports documenting test objectives, results, conclusions, and next steps
  • Apply sound engineering judgment to balance aggressive timelines with risk and uncertainty
  • Contribute to continuous improvement initiatives to enhance performance development processes
  • Ensure compliance with safety standards and regulatory requirements
  • Follow company policies related to data management, time reporting, IP protection, and compliance
  • Communicate clearly and professionally with cross-functional teams
  • Demonstrate ownership, maintain a positive and open-minded attitude, and adapt effectively to challenges and setbacks
Requirements:
  • Bachelor's degree in Mechanical Engineering or a related field (Master's preferred)
  • 5+ years of experience in engine performance development, testing, or calibration
  • Strong understanding of internal combustion engines (rotary engine experience is a plus)
  • Experience developing and executing engine test plans and analyzing performance data
  • Familiarity with engine simulation tools such as GT-Power (or similar)
  • Hands-on experience with engine testing equipment and measurement tools
  • Strong analytical and problem-solving skills with the ability to interpret complex datasets
  • Experience working in cross-functional engineering teams, including test and simulation
  • Ability to clearly communicate technical findings to both technical and non-technical stakeholders
  • Experience in an R&D or prototype environment is highly preferred
  • Self-starter with strong attention to detail and a proactive, ownership-driven mindset
Benefits & Perks:
  • Flexible PTO: We value work-life balance and encourage time to rest and recharge.
  • Health & Wellness: Comprehensive medical and voluntary dental, and vision coverage - you choose what works best for you.
  • Equity Participation: Permanent employees receive RSUs (Restricted Stock Units).
  • 401(k) Match: We offer a 401k w/100% matching up to 3% of your salary and then 50% of contributions between 3-5%
