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, andhighly 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
