These tools are used by the world’s leading electronics companies to design, simulate, and validate high-frequency, high-speed, and highly complex electronic systems.Within DES, the R&D center in Ghent, Belgium develops cutting-edge physics-based simulation technology across electromagnetics, photonics, and now thermal modeling. The team is currently expanding its thermal simulation capabilities to support next-generation PCB, package, and 3D-IC design.The environment is international, highly technical, and collaborative, with engineers from more than 20 nationalities working on globally deployed simulation platforms.About the RoleWe are hiring a Senior Thermal CAD Software Developer to help build and scale Keysight’s thermal CAD simulation platform for electronic design.This role sits at the intersection of:Physics-based thermal modelingHigh-performance numerical algorithmsLarge-scale C++ simulation softwareYou will not just write code — you will shape how thermal simulation is delivered to electronics engineers designing PCBs, packages, and 3D-ICs. You will work closely with product managers, R&D, QA and customer-facing teams to ensure the solver technology translates into usable, high-value design tools.ResponsibilitiesArchitect, design, and implement thermal simulation capabilities for Keysight’s EDA platformIntegrate thermal solvers into PCB, package, and 3D-IC design workflowsDevelop and optimize numerical algorithms for large-scale thermal simulationsDebug and resolve solver accuracy, convergence, and performance issuesWork with Product Management and Technical Support to translate customer needs into solver and workflow featuresApply best practices in modern C++ software engineering (modular design, testability, performance, maintainability)Contribute to code reviews, CI pipelines, documentation, and quality standardsQualificationsRequired QualificationsMSc or PhD in Thermal Engineering, Applied Mathematics, Computer Science, Physics, or similarStrong background in computational thermal modeling, CFD, or numerical simulation (e.g., OpenFOAM or similar)Hands-on experience developing large-scale numerical solversExpert-level C++ (modern C++, not just basic scripting)Experience designing robust, high-performance simulation softwareStrong analytical and problem-solving skillsAbility to collaborate across international, multi-disciplinary teamsDesired QualificationsPython for scripting, prototyping, or automationKnowledge of electronics thermal design (PCB, IC packages, power electronics, 3D-IC)Experience with high-performance computing (HPC) and solver optimizationExperience with Git, CI/CD, and modern build systemsCareers Privacy Statement***Keysight is an Equal Opportunity Employer.***
