Our team is composed of passionate professionals dedicated to making a tangible impact on the future of industrial manufacturing. Join us in our mission to transform the industry and contribute to a more sustainable world.

The Role

We are seeking a highly motivated Simulation Engineer to join our core engineering team. In this role, you will be responsible for developing, running, and analyzing high-fidelity simulations of our thermofluid and mechanical systems. Your work will directly influence the design and performance of our core technology, from initial concept through prototyping and validation. This is a critical role for a candidate who thrives on solving complex, real-world problems and is looking for their next big challenge.

Responsibilities

• Develop and validate multi-domain physics models, analyzing fluid flow, thermal performance, structural integrity, and dynamic behavior of systems and components, including heat exchangers and turbomachinery.
• Collaborate closely with design and test engineering teams to iterate on designs based on simulation results.
• Process, analyze, and present simulation data to the broader team to provide actionable insights that will drive key engineering decisions.
• Develop and refine simulation methodologies to improve predictive accuracy and computational efficiency.
• Assist in correlating simulation results with experimental test data to ensure model fidelity.

Required Qualifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related field.
• 3+ years of professional experience in a simulation-focused engineering role.

• Strong foundation in thermodynamics, fluid mechanics, and heat transfer.
• Proficiency in scripting for simulation automation and data analysis using languages like Python or MATLAB.
• Experience with 0-d and 1-d analysis methods in multiple domains (e.g. fluids, thermodynamics, heat transfer, structural mechanics).

Preferred Qualifications

• Experience with multi-domain physics simulation packages such as Simulink or Modelica.
• Experience modeling rotating machinery, multiphase flows, or compressible fluids.
• Experience with conjugate heat transfer simulations.
• Hands-on experience with CAD software (e.g. NX or SolidWorks).
• A track record of taking ownership of projects and delivering results in a fast-paced environment.
