Staff Simulation Engineer

What You Will Do

• Lead CFD and thermal-fluid simulation of active cold plate designs, including laminar and turbulence modeling, and fluid dynamic behavior at the chip interface
• Develop and validate multi-physics models, such as conjugate heat transfer (CHT) and, where needed, fluid-structure interaction (FSI), correlating predicted thermal and hydraulic performance to prototype test data
• Collaborate with mechanical, mechatronics, and PCB design engineers to translate simulation results into actionable design changes
• Simulate potential leakage pathways and failure modes in cold plate and manifold assemblies across the overall cooling system
• Support design of experiments (DOE) for prototype validation testing correlated against simulation predictions
• Own simulation toolchain setup, meshing strategy, and solver configuration for complex internal cold plate geometries
• Support the invention disclosure and patent process by generating simulation data, figures, and technical substantiation
• Develop 1D system-level simulation models, reduced-order models or empirical correlations to accelerate design iteration
• Support customer-facing technical presentations with simulation-backed performance data

Who You Are (Basic Qualifications)

• BS in Mechanical Engineering or equivalent
• 7+ years of experience in CFD, FEA, conjugate heat transfer (CHT), and multi-physics simulation
• Proficiency with commercial CFD tools (Ansys Fluent, CFX, STAR-CCM+, or equivalent)
• Proficiency with FEA tools (Ansys Mechanical, Abaqus, or equivalent)
• Experience simulating liquid cooling hardware: cold plates, manifolds, heat exchangers
• Strong understanding of fluid dynamics, heat transfer, and thermal-hydraulic system design
• Demonstrated experience correlating simulation results to physical test data

What Will Put You Ahead

• MS or PhD in Mechanical Engineering, Thermal Sciences, or a related field
• Experience with advanced meshing techniques (dynamic meshing, adaptive meshing, etc.) for dynamic models, such as rotating machinery or pumps
• Experience with two-phase flow or boiling heat transfer simulation
• Familiarity with Open Compute Project (OCP) thermal standards
• Experience developing 1D system-level simulation models, reduced-order models, or surrogate models for rapid design iteration
• Python or MATLAB scripting for simulation automation and post-processing
• Experience supporting patent disclosures with simulation-based technical evidence
