Sr. Principal Engineer, Systems (Plasma & Multi-Scale Simulation Scientist)
Originally posted 31 March 2026 by the employer.
Focus on bridging plasma physics, surface chemistry, and feature-scale behavior across PEALD, PECVD, ALE, and RIE.
About the role
This role focuses on bridging plasma physics, surface chemistry, and feature-scale behavior to enable predictive, physics-based simulation workflows within the Simulation and Modeling Hub. The work directly supports semiconductor process development across PEALD, PECVD, ALE, and RIE.
What you'll do
- Develop and apply plasma simulation models, including fluid and hybrid CCP/ICP approaches. - Bridge multiple scales, spanning plasma–surface interactions, molecular/first-principles insights, and feature-scale behavior. - Integrate plasma modeling with CFD, thermal, and multi-physics simulations. - Collaborate with experimental teams to validate models using in-situ and ex-situ diagnostics. - Translate modeling insights into actionable process and equipment guidance. - Contribute to S&M-Hub roadmap development, best practices, and advanced modeling workflows.
What you'll need
- Ph.D. in Applied Physics, Plasma Physics, Materials Science, Chemical Engineering, or a related field. - Background in plasma-assisted semiconductor processes including PEALD, PECVD, ALE, and RIE. - Demonstrated experience in computational plasma modeling. - Demonstrated ability to connect fundamental modeling with experimental validation and manufacturing relevance.
Nice to have
- Experience with first-principles, molecular dynamics, or surface reaction modeling. - Exposure to feature-scale or device-relevant plasma simulations. - Familiarity with multi-physics coupling and reduced-order (ROM) or hybrid modeling approaches. - Experience in industrial R&D or advanced technology development environments.
Skills: plasma modeling, multi-scale simulation, PECVD, RIE, process development
