Senior Thermal Simulation Engineer; onsite

Responsibilities

• Perform hand calculations, select appropriate correlation coefficients, and build simple scaling models.
• Perform coupled thermo‑fluid simulations using CFD software to predict pressure drop and thermal performance.
• Provide guidance and input on customer development projects.
• Develop and improve best practices around simulation.

On‑site presence 4 days a week, with an option to work remotely 1 day a week. Candidates must be within commuting distance or able to relocate.

Only US citizens and/or Permanent Residents of the US will be considered, as sponsorship is not available for this position.

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or another relevant field.
• 7+ years of experience in thermal‑fluid simulation and analysis, including but not limited to comfort with selecting turbulence closures, running mesh refinement studies, estimating model error, and extracting dimensionless correlation coefficients from simulations.
• Experience with CFD simulation software.
• Experience with a wide range of reference literature on calculating thermal and fluid behavior of components.
• Ability to deliver results in a quickly evolving environment, delivering estimates for thermal performance of a design within a few days to accelerate customer‑facing projects.
• Familiarity with design engineering work, specifically an understanding of what an engineering design process looks like and how their work informs that process.

Hiring salary range: $105,000 – $160,000, commensurate with education, experience, knowledge, skills, and abilities.
