- Translate simulation insights into actionable design recommendations that improve product performance, reliability, and manufacturability.
- Partner with product engineering, validation, and system teams to identify thermal risks early and support successful product development programs.
- Drive correlation between simulation predictions and physical test data, improving confidence in virtual qualification methodologies.
- Contribute to the development of simulation standards, best practices, and predictive engineering capabilities across the organization.
- Support innovation initiatives involving digital twins, reduced-order models, and simulation-driven product development approaches.
- Communicate complex thermal phenomena and engineering findings effectively to technical and non-technical stakeholders.
- Mentor junior engineers and contribute to the growth of simulation capabilities within the organization.

Who You Are (Basic Qualifications)

- Bachelor's degree in Mechanical Engineering, Thermal Engineering, Aerospace Engineering, or a related engineering discipline.
- 3+ years of experience in thermal analysis, CFD simulation, or heat transfer engineering within product development environments.
- Strong understanding of heat transfer fundamentals including conduction, convection, radiation, and conjugate heat transfer.




- Experience using commercial CFD and thermal simulation tools such as Ansys Fluent, Ansys Icepak, Simcenter STAR-CCM+, Flotherm, or OpenFOAM.
- Knowledge of fluid mechanics, turbulence modeling, numerical methods, and simulation best practices.
- Experience validating simulation results through engineering calculations, analytical methods, or physical testing.
- Solid communication and problem-solving skills with the ability to collaborate across global engineering teams.

What Will Put You Ahead

- Master's degree in Thermal, Mechanical, Aerospace, or a related engineering discipline.
- Experience with electronics cooling, thermal characterization, heat sink design, or thermal interface materials (TIMs).
- Knowledge of liquid cooling systems including cold plates, microchannels, manifolds, and coolant flow optimization.
- Experience supporting data center, AI infrastructure, server cooling, or high-speed connectivity products.
- Familiarity with thermal qualification standards and industry practices such as ASHRAE, JEDEC, or OCP.
- Proficiency in Python, MATLAB, or similar tools for simulation automation, data analysis, and post-processing.
- Exposure to digital twin development, surrogate modeling, AI/ML-assisted simulation, or reduced-order thermal models.
- Experience mentoring engineers and providing technical leadership on simulation programs.
