Job description

Sr. Principal Engineer, Systems (Plasma & Multi-Scale Simulation Scientist)

Simulation and Modeling Hub

Role Summary

We are seeking a Senior Plasma & Multi-Scale Simulation Scientist to strengthen and expand plasma modeling capabilities within the Simulation and Modeling Hub (S&M-Hub). This role focuses on bridging plasma physics, surface chemistry, and feature‑scale behavior to enable predictive, physics‑based simulation workflows supporting advanced semiconductor process development (PEALD, PECVD, ALE, RIE).

Key Responsibilities

• Develop and apply plasma simulation models (fluid and hybrid CCP/ICP)
• Bridge multiple scales including 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

Required Qualifications

• Ph.D. in Applied Physics, Plasma Physics, Materials Science, Chemical Engineering, or related field
• Strong background in plasma‑assisted semiconductor processes (PEALD, PECVD, ALE, RIE)
• Demonstrated experience in computational plasma modeling
• Ability to connect fundamental modeling with experimental validation and manufacturing relevance

Preferred Qualifications

• 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
