Senior Process Engineer Epitaxy | Eindhoven

Want to make your mark on our time? Become a Senior Process Engineer Epitaxy at TNO in Eindhoven!

About this position

At the forefront of Europe's photonics innovation, TNO is building a state-of-the-art pilot line for Indium Phosphide (InP) photonic chips at the High Tech Campus in Eindhoven. As part of the EU-funded PIXEurope program, this pilot line will enable the transition from groundbreaking research to large-scale industrial manufacturing, making advanced photonic technologies faster, more reliable, and widely accessible. To make this ambitious step a reality, we are looking for a Senior Process Engineer Epitaxy. In this role, you will play a key role in developing and optimizing the critical processes that drive our pilot line. With your expertise, you will help build Europe's next-generation capability in integrated photonics, ensuring that innovation is translated into stable, scalable, and high-yield production.

What will be your role?

As Senior Process Engineer Epitaxy, you are responsible for developing, optimizing, and managing epitaxy processes (MOCVD) for 6-inch Indium Phosphide wafer manufacturing. Working in a high-tech cleanroom environment, you ensure process stability, yield improvement, and smooth release of 6-inch wafer processes on advanced equipment. You collaborate closely with R&D, equipment engineers, and quality assurance to bridge the gap between innovation and industrial manufacturing.

Key responsibilities include:

• Developing and improving epitaxy and related manufacturing processes.
• Qualify and release 6-inch wafer processes on installed epitaxy tools.
• Analyzing process data, performing root cause analyses, and applying statistical methods (SPC, FMEA, DoE).
• Supporting wafer manufacturing operations by troubleshooting and preventing disruptions.
• Ensuring process stability and quality across production lines.
• Taking ownership of improvements projects and the introduction of new epitaxy tools and processes.
• Collaborating with cross-functional teams (R&D, Equipment, QA) and reporting progress to management.

• A completed MSc or BSc degree in physics, chemistry, materials science, electrical engineering, or a related field.
• Proven experience with semiconductor or photonic process engineering in wafer manufacturing/cleanroom environments.
• Strong knowledge of epitaxy processes (MOCVD, MBE) and related semiconductor processing steps.
• Experience in process optimization, statistical methods (SPC, FMEA, DoE), and yield improvement.
• The ability to troubleshoot, resolve process issues, and ensure production continuity.
• 8+ years of relevant experience, including project leadership, introduction of new processes/tools, and mentoring of junior colleagues.
