Principal Engineer, Systems Engineering, Sensor & Laser Technologies
Originally posted 9 November 2026 by the employer.
About the role
The Principal Engineer, Systems Engineering in the Sensor Technology Group is responsible for the development, integration, qualification, and deployment of advanced sensing and laser-enabled technologies across ASM product platforms. This role focuses on laser-based process solutions, including laser heating, laser-assisted pyrometry, wafer leveling, wafer centering, and optical metrology.
What you'll do
- Lead the development, integration, and qualification of laser-enabled technologies and subsystems for semiconductor manufacturing equipment.
- Define system architectures, performance requirements, interfaces, and validation strategies for laser heating, laser-assisted temperature measurement, wafer leveling, and wafer centering subsystems.
- Evaluate and select laser sources, beam-delivery architectures, optical components, and metrology technologies for advanced process-control applications.
- Drive development of laser-assisted pyrometry solutions to improve temperature measurement accuracy under varying emissivity and process conditions.
- Lead proof-of-concept activities, technology demonstrations, and product qualification programs while establishing best practices for laser subsystem reliability, safety, and performance validation.
- Support thermal characterization, process optimization, and advanced process-control initiatives across multidisciplinary engineering teams.
What you'll need
- Deep technical expertise in systems thinking, optics, sensors, lasers, and data analytics applied to semiconductor manufacturing equipment.
- Proven experience leading multidisciplinary projects spanning Mechanical, Electrical, Firmware, Software, Process, and Product Engineering teams.
- Technical background developing measurement and control solutions, including system requirements definition, interface specification, and validation strategies.
- Demonstrated ability to develop laser-based solutions for wafer alignment, leveling, centering, or geometry measurement applications.
Nice to have
- MS or PhD in Optical Engineering, Physics, Mechanical Engineering, Electrical Engineering, Systems Engineering, or related technical discipline.
- Experience with laser-based measurement systems, laser heating technologies, and optical metrology systems.
- Experience with pyrometry, thermal metrology, wafer alignment, laser triangulation, or optical positioning systems.
- Knowledge of laser beam delivery, optical design, laser safety, and semiconductor thermal processing applications.
- Experience integrating lasers and optical subsystems into semiconductor manufacturing equipment.
