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.
