The CMP Fundamentals team is seeking an experienced scientist or engineer to serve as a technical leader in the development, validation, and application of predictive modeling capabilities supporting next‑generation CMP consumables and processes. This position will combine rigorous scientific investigation, advanced characterization, experimental research, and computational modeling to build fundamental understanding of the relationships between consumable properties, process conditions, and polishing performance.

A key objective of this role is to establish confidence in simulation‑driven decision making by ensuring models are physically meaningful, numerically reliable, experimentally validated, and aligned with business needs. The successful candidate will define what should be modeled, challenge assumptions, improve model fidelity, quantify uncertainty, and drive the long‑term simulation capability roadmap for CMPT. This role is intended to develop a long‑term CMP technical expert capable of owning complex technical problem statements, mentoring future scientists and engineers, and serving as a critical technical partner for product development, customer support, and innovation efforts.

Approximately 20% travel may be required to customer sites, development facilities, collaborator locations, and technical review meetings. This position is ultimately intended to be based onsite in Newark, Delaware. To support recruitment of exceptional candidates, flexibility may be provided during the initial onboarding and transition period. Candidates should be willing to relocate to the Newark area and work onsite as the long‑term expectation for the role.
