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
