Research Scientist, Analytical R&D

The Role:  

Entegris is currently seeking an Analytical Research Scientist to join our Research & Development Team in Aurora, Illinois. 

In this role, you will collaborate closely with cross-functional Entegris teams in a fast-paced, innovative environment. The successful candidate will play a key role in applying advanced analytical techniques to develop creative solutions that support the development and commercialization of high-performance advanced materials solutions for the semiconductor industry. 

What You’ll Do 

• Develop and apply comprehensive materials characterization strategies using state-of-the-art analytical instrumentation and techniques, including NMR (Nuclear Magnetic Resonance) spectroscopy, to build mechanistic understanding of structure, composition, and performance relationships in complex material systems. 

• Collaborate closely with analytical and product development teams to develop quantitative characterization methods that elucidate structure–function relationships across nanoparticles, polymers, and chemical additives in aqueous systems. 

• Expand and strengthen in-house characterization, simulation, and theoretical capabilities in colloidal science, polymer science, and materials science while collaborating with external laboratories, universities, and instrument vendors to identify and implement valuable characterization techniques. 

• Design, develop, and execute new analytical capabilities and methodologies that support new product development, intellectual property generation, emerging technologies, and technical problem-solving efforts. 

• Lead the planning, execution, and documentation of analytically focused projects, ensuring technical rigor and alignment with business objectives. 

• Serve as a Subject Matter Expert in analytical characterization—with particular emphasis on NMR spectroscopy—supporting multiple business areas across the company. 

• Communicate findings and conclusions effectively to both technical and non-technical audiences in a timely manner and contribute to innovation submissions and patent filings as needed. 

What We Seek 

• Ph.D. in Chemistry, Physics, Chemical Engineering, Materials Science, or a related discipline is required. 

• Minimum of 3 years of industrial experience, or Postdoctoral experience in academia, with at least 1 year in a field highly relevant to CMP or colloidal science, is strongly preferred. 

• Experience building and maintaining academic–industrial collaborations is a plus. 

• Strong expertise in NMR (Nuclear Magnetic Resonance) spectroscopy, along with experience in one or more analytical techniques used to characterize organic and inorganic materials. These may include, but are not limited to: LC-MS, HPLC, IC, ICP, FTIR, electron microscopy (SEM, TEM, STEM), XRD, XRF, EDX, particle size analysis (CPS, SPOS, DLS, laser diffraction), GPC/SEC, electroanalytical measurements, rheometry, or interfacial characterization methods. 

• Demonstrated ability to develop novel analytical methodologies and approaches for complex, multifaceted projects, particularly using NMR spectroscopy. Experience with additional analytical techniques such as LC-MS is a plus. 

• Experience in advanced NMR techniques (homo/heteronuclear 1D & 2D, low-field NMR, Solid-State NMR). 

• Strong chemical and polymer characterization and analytical problem-solving skills. 

• Strong critical thinking and attention to detail, with a proven ability to generate innovative solutions to complex technical challenges. 

• Results-driven, self-motivated individual with the ability to set goals, plan effectively, and execute sophisticated research projects independently. 

• Ability to manage multiple priorities while clearly and concisely communicating timelines, progress, and results to internal partners/stakeholders. 

• Solid understanding of statistical principles and methodologies, with the ability to apply them effectively to analyze and interpret analytical datasets.
