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 highlycomplex 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.
