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
