What is a modeling and simulation engineer?

Modeling and Simulation Engineers are professionals who use mathematical models and computer simulations to analyze complex systems and predict their behavior. They work in various industries, including aerospace, defense, healthcare, and manufacturing, to improve product design, optimize processes, and support decision-making. Their work often involves creating virtual prototypes, running simulations to test different scenarios, and interpreting results to provide insights for engineering projects. These engineers typically have strong backgrounds in mathematics, physics, and computer science.

What are the key skills and qualifications needed to thrive as a modeling and simulation engineer?

To thrive as a Modeling and Simulation Engineer, you need a strong background in mathematics, physics, computer science, and engineering principles, typically supported by a relevant degree. Proficiency with simulation software (such as MATLAB, Simulink, or ANSYS), programming languages (like Python or C++), and sometimes certifications in modeling tools are highly valued. Analytical thinking, problem-solving, and effective communication are essential soft skills for translating complex systems into accurate models and collaborating with multidisciplinary teams. These skills are crucial for ensuring the accuracy, reliability, and usability of simulations that inform critical engineering decisions.

What are some common challenges a modeling and simulation engineer faces when integrating new models into existing systems?

A common challenge for Modeling and Simulation Engineers is ensuring that new models are compatible with existing simulation frameworks and data sources. This often involves resolving discrepancies in data formats, model fidelity, and simulation timing, as well as validating that the integrated system produces accurate and reliable results. Collaboration with software developers, data analysts, and subject matter experts is essential to troubleshoot integration issues and maintain system performance. Effective communication and thorough documentation are key to overcoming these integration hurdles.

What is the difference between Modeling And Simulation Engineer vs Systems Engineer?

AspectModeling And Simulation EngineerSystems Engineer
CredentialsBachelor's or Master's in Engineering, Computer Science, or related fields; certifications like INCOSEBachelor's or Master's in Engineering, Systems Engineering, or related fields; certifications like INCOSE
Work EnvironmentDesigning and developing simulation models, testing scenarios in labs or software environmentsIntegrating system components, coordinating across engineering teams, often in project offices
Industry UsageDefense, aerospace, automotive, and manufacturing sectorsDefense, aerospace, IT, and complex system development industries

While both roles require engineering backgrounds and similar certifications, Modeling And Simulation Engineers focus on creating and testing simulation models, whereas Systems Engineers oversee the integration and functionality of entire systems. Both collaborate closely but serve different specialized functions within engineering projects.

Job description

About Commonwealth Fusion Systems:
Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.
Combining decades of research, top talent, and new technologies, we're designing and building commercially viable fusion power plants. And we're working with policymakers and suppliers to build the energy industry of the future.
We're in the best position to make it happen. Since 2018, we've raised nearly $3 billion in capital, making us the largest and leading private fusion company in the world.
Now we're looking for more thinkers, doers, builders, and makers to join us. People who'll bring new perspectives, solve tough problems, and thrive as part of a team.
If that's you and this role fits, we want to hear from you.
Join the power movement as a Staff Modeling and Simulation Engineer
We're looking for a Staff Modeling and Simulation Engineer to join our design team to help build next-generation hardware. In this role, you will serve as a lead technical expert for advanced simulations, driving the predictive validation of complex hardware systems.
This role requires a high-level practitioner in multi-physics simulation who can comfortably model complex interactions across thermal, structural, fluid flow, and chemical regimes. If you enjoy solving deeply complex physics problems, applying rigorous modeling standards, and working in a collaborative, fast-paced environment to deliver first-of-a-kind hardware, this is your opportunity to make an impact.
What you'll do:
  • Execute Simulation and Modeling: Lead advanced Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) for advanced processing equipment
  • Run Multi-Physics Analysis: Build, run, and evaluate highly coupled simulations covering structural mechanics, high-temperature thermal management, fluid/gas flow dynamics, and chemical reaction kinetics
  • Apply Engineering Best Practices: Implement engineering workflows for simulation data management, mesh convergence criteria, and rigorous verification and validation (V&V) protocols using physical test data
  • Drive Design Reviews: Provide analytical leadership during technical design reviews, verifying structural margins, thermal stress distributions, and flow uniformity to guide design choices
  • Collaborate & Interface: Partner closely with cross-functional teams, including Mechanical Designers, Electrical Engineers, Materials Scientists, and Chemical Specialists, to translate simulation insights into actionable hardware modifications
  • Project Accountability: Own and report on modeling milestones, timelines, and computational resources to stakeholders, ensuring on-time and in-spec delivery
  • Mentor Talent: Coach and mentor junior engineering staff on modeling methodologies, simulation accuracy, and the practical application of finite element principles to real-world hardware
  • Get Things Done: Act with speed to solve critical engineering bottlenecks, validating design optimization paths from concept through prototype deployment

What we're looking for:
  • Education: Master's or PhD degree in Mechanical Engineering, Aerospace Engineering, Physics, or a related field with a heavy focus on computational mechanics and multi-physics modeling
  • Experience: 10+ years of experience in simulation and predictive analysis of complex R&D systems
  • Software Mastery: Advanced, hands-on expert in ANSYS, COMSOL Multi-physics, or equivalent high-end FEA/CFD simulation platforms
  • Multi-Disciplinary Analytical Expertise: Proven track record of successfully running coupled simulations (e.g., fluid-structure interaction, thermal-structural behavior, and chemical reaction modeling)
  • Empirical Correlation: Ability to bridge the gap between virtual models and the shop floor by validating simulation results against physical test metrics like strain gauge data, thermal imaging, and flow sensors
  • Leadership: Demonstrated ability to influence hardware design direction through analytical data and lead cross-functional initiatives in a matrixed environment

Bonus points for:
  • Standards Knowledge: Familiarity with applying industry codes to simulation-driven design validation
  • Motion & Dynamics: Experience running transient dynamic simulations or modeling precision motion systems in extreme thermal environments

Must-have requirements:
  • Ability to lift up to 25 lbs occasionally
  • Perform activities such as stooping, climbing, standing, sitting for extended periods of time
  • Willingness to travel or work required nights/weekends/on-call occasionally
  • Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics
