About The Team Keysight Design Engineering Software (DES) is Keysight’s advanced software organization building industry-leading Electronic Design Automation, Computer-Aided Engineering, and Multiphysics simulation platforms. 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 Role We 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 modeling High-performance numerical algorithms Large-scale C++ simulation software You 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. Responsibilities Architect, design, and implement thermal simulation capabilities for Keysight’s EDA platform Integrate thermal solvers into PCB, package, and 3D-IC design workflows Develop and optimize numerical algorithms for large-scale thermal simulations Debug and resolve solver accuracy, convergence, and performance issues Work with Product Management and Technical Support to translate customer needs into solver and workflow features Apply best practices in modern C++ software engineering (modular design, testability, performance, maintainability) Contribute to code reviews, CI pipelines, documentation, and quality standards Qualifications Required Qualifications MSc or PhD in Thermal Engineering, Applied Mathematics, Computer Science, Physics, or similar Strong background in computational thermal modeling, CFD, or numerical simulation (e.g., OpenFOAM or similar) Hands-on experience developing large-scale numerical solvers Expert-level C++ (modern C++, not just basic scripting) Experience designing robust, high-performance simulation software Strong analytical and problem-solving skills Ability to collaborate across international, multi-disciplinary teams Desired Qualifications Python for scripting, prototyping, or automation Knowledge of electronics thermal design (PCB, IC packages, power electronics, 3D-IC) Experience with high-performance computing (HPC) and solver optimization Experience with Git, CI/CD, and modern build systems Careers Privacy Statement***Keysight is an Equal Opportunity Employer.*** #J-18808-Ljbffr
