About The Position

Entegris is seeking a Senior Scientist, Organic Chemist to join its Research and Development team at its Aurora site. The role focuses on developing leading-edge technologies for semiconductor applications in collaboration with scientists and engineers across disciplines. The Senior Scientist will design, synthesize, isolate, characterize, and purify small organic molecules, including silanes, to meet defined performance targets. The role includes interpreting characterization data and applying structure–property relationships to improve material performance. The scientist will plan, execute, and document a research program; help scale promising chemistries from laboratory work to pilot and production; collaborate with internal stakeholders and cross-functional teams; present technical findings to technical and non-technical audiences; and contribute to laboratory safety practices. Entegris describes its culture as collaborative and values-driven, with employees encouraged to contribute ideas. The company offers a total rewards package that includes compensation of $85,500–$120,000 per year, annual bonus eligibility, paid time off, a 401(k) plan with employer match, health, dental and vision insurance, and education assistance. Immigration-related sponsorship is not provided for this role.

Requirements

Ph.D. in Chemistry, with a focus in organic or silane chemistry.
Demonstrated experience designing, synthesizing, isolating, and purifying small organic molecules.
Hands-on expertise characterizing self-prepared materials, selecting appropriate techniques, interpreting data, and explaining implications for material performance.
Experience adjusting chemical and physical properties using structure–property relationships.
Research contributions demonstrated through peer-reviewed publications, patents or patent applications, conference presentations, internal technical reports, or products advanced to commercialization.
Ability to plan, execute, and document defined research activities on schedule.
Clear written and verbal communication with technical and non-technical audiences.
Commitment to laboratory safety and participation in safety initiatives.

Nice To Haves

Postdoctoral experience in a university or industry setting, with examples of independent research in diverse areas.
Significant experience with silane chemistry.
Scale-up or kiloscale synthesis experience.
Demonstrated collaboration with team members of different levels or career stages.
Six Sigma Green Belt or Black Belt, with knowledge and application of statistical tools such as DOE analysis and programs such as Minitab or JMP.
Strong written and presentation communication skills with peers, research associates, and non-technical collaborators.

Responsibilities

Design, synthesize, isolate, and purify small organic molecules, including silanes, to meet defined performance targets for semiconductor applications.
Characterize synthesized materials and interpret data, including for structure confirmation using techniques such as NMR, FTIR, LC, GC, and MS.
Apply structure–property relationships to systematically tune material performance and design experiments that distinguish influential variables.
Plan, execute, and document a research program, maintaining records suitable for internal review, technology transfer, and intellectual property filings.
Partner with process and manufacturing engineers to scale promising chemistries from laboratory to pilot and production, including raw material selection, process parameter definition, and troubleshooting.
Work with internal stakeholders to understand development needs and identify opportunities for improvement.
Prepare and deliver technical presentations to R&D colleagues, internal stakeholders, and suppliers, and explain technical findings to non-technical audiences.
Collaborate with chemists, engineers, customer representatives, quality specialists, and production engineers across multiple Entegris sites.
Follow and help improve laboratory safety practices.
