Senior CFD Engineer

Requirements

• B.S. in Mechanical, Aerospace, or a related engineering field (M.S./PhD a plus)
• Strong fundamentals in heat transfer and fluid mechanics; comfort reasoning from first principles and sanity-checking results
• 4+ years of hands-on CFD experience in thermal-fluids applications (more experience welcomed; we can level this role)
• Experience with heat exchangers or closely related mass/heat transfer hardware (compact HX, manifolds, internal flows, finned passages, etc.)
• Proficiency in at least one major CFD solver: ANSYS Fluent/CFX, STAR-CCM+, OpenFOAM, or COMSOL
• Practical meshing and modeling judgment: boundary layers, y+, turbulence model selection, convergence criteria, grid independence
• Ability to communicate results clearly to non-CFD stakeholders and defend assumptions under schedule pressure
• Multi-phase or boiling/condensing modeling experience is a plus
• Experience with flow distribution challenges and mitigation (distributors, baffles, headers) is a plus
• Experience with flow-induced vibration considerations or coupling CFD insights to structural risk is a plus
• Python-based automation of meshing/runs/post-processing; comfort on HPC environments (Slurm/PBS) is a plus
• Experience producing decision-grade analysis packages in high-reliability industries is a plus

Additional Information

Last Energy is building productized nuclear plants with manufacturing-style repeatability. We're hiring a CFD Engineer focused on heat exchangers to drive thermal-fluid analysis from first-pass sizing through detailed geometry decisions. You'll own the CFD workflow end-to-end and turn simulations into clear trade studies and recommendations that directly inform hardware design (ΔP, effectiveness, flow distribution, hot spots), while continuously improving the speed and consistency of how we model and communicate results.
