Senior Scientist - EUV Research - San Diego, CA, United States
$127,200 - $174,900 USD yearly
Originally posted 6 October 2026 by the employer.
About the role
This research focuses on the generation of molten tin droplets, a key ingredient for the laser produced plasma (LPP) EUV source.
What you'll do
- Guide the development of high-level architecture for droplet generation in the EUV source.
- Lead the design of droplet generation hardware and build metrology and testing capabilities.
- Provide input to technology roadmaps and define experimental designs for scientific learning objectives.
- Develop and execute system and subsystem performance tests, analyzing results to extract knowledge.
- Troubleshoot issues with droplet generation, tin delivery, and optical systems to improve performance.
- Build, improve, and maintain droplet generator models anchored by experimental validation.
- Document learning and communicate knowledge to engineering and product development teams.
What you'll need
- PhD or MS degree with 3+ years of relevant experience in Materials Engineering, Mechanical Engineering, Chemical Engineering, Material Science, Physics, or Optics.
- Hands-on experience with complex system design and build, including rapid prototyping, characterization, and troubleshooting via metrology techniques.
- Deep understanding of scientific research methods, with demonstrated knowledge in metrology development and data analysis.
- Extensive experience with experimental data analysis and development of data analysis tools with Matlab or Python and data acquisition systems like NI Labview.
- Demonstrated ability to manage and lead a research project involving multiple stakeholders and constraints.
Nice to have
- Experience with glass, ceramics, refractory materials, high pressure sealing technology in corrosive environments.
- Experience with microfluidics, liquid jet breakup, and droplet coalescence; piezoelectricity; and acoustics.
- Familiarity with modeling microfluidics, liquid jet breakup, droplet coalescence, piezoelectricity, or acoustics.
- Experience with high pressure applications such as water jet cutting, jet breakup, and nozzle design.
- Experience architecting high-level model structure into digestible components with crisp interfaces.
- Experience coordinating multiple components of a model; experience implementing physics concepts into models.
- Experience with droplet formation, sprays, common-rail diesel, and/or injectors.
- Experience with acoustics designs: resonant cavities in the kHz/MHz regime; transfer function design for enhancing/suppressing energy transfer into liquids; piezo-driven system design.
