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

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
Apply today to be part of what’s next.
We make the tech that enables the chips in devices which improve lives around the world. We do this with an eye to the future, pushing the boundaries of what’s possible through cutting-edge innovation, and driving the next wave of technological breakthroughs that shape how we live, work, and connect.
