About The Position

Entegris is seeking a Senior Scientist, Analytical R&D to join its Analytical R&D team at the Danbury, Connecticut facility. The role leads development, validation, and continuous improvement of analytical methods for characterizing complex materials, mixtures, and formulations. It applies advanced analytical chemistry, metrology, and statistical techniques to support new-product development, improve existing products, resolve technical problems, and respond to internal and external customer needs. The scientist works with global R&D, engineering, manufacturing, quality, sales, marketing, and external laboratory partners. The role also provides technical guidance and training to laboratory colleagues, supports analytical-development programs and cross-functional reviews, and promotes safe, audit-ready laboratory practices in laboratory and cleanroom environments. Travel of approximately 10% to 20%, including international travel, is required.

Requirements

Bachelor’s degree or higher in Chemistry, Analytical Chemistry, Chemical Engineering, Materials Science, or a closely related scientific discipline.
At least three years of relevant experience in an analytical, R&D, product-development, or comparable laboratory environment.
Demonstrated experience developing, validating, or improving analytical methods for complex materials, mixtures, formulations, or high-purity products.
Working knowledge of one or more relevant analytical techniques, with a focus on chromatography.
Ability to design experiments, analyze technical data, evaluate method performance, and translate findings into clear conclusions and recommendations.
Understanding of measurement-system analysis, method capability, statistical analysis, root-cause investigation, and corrective-action principles.
Experience preparing controlled technical documentation, including SOPs, work instructions, validation protocols, qualification records, and reports.
Ability to work safely with hazardous materials and follow applicable laboratory, cleanroom, chemical-handling, and personal-protective-equipment requirements.
Strong project-management, prioritization, and problem-solving skills, including the flexibility to manage multiple assignments and respond to changing business needs.
Effective written and verbal communication skills, including professional proficiency in English.
Ability to collaborate across functions, cultures, languages, and geographic locations.
Ability and willingness to travel approximately 10% to 20%, including international travel.

Nice To Haves

Hands-on expertise with high-purity chemical analysis or analytical characterization of complex formulations.
Experience qualifying new analytical instrumentation or transferring analytical methods between laboratories or global sites.
Knowledge of semiconductor materials, specialty chemicals, high-purity manufacturing, or contamination-control requirements.
Experience supporting new-product introduction and working directly with manufacturing, quality, commercial teams, external laboratories, or customers.

Responsibilities

Develop, optimize, validate, and transfer analytical methods for complex analyses.
Design and execute analytical experiments; interpret data, reach technically sound conclusions, and communicate results through reports, presentations, and discussions with technical teams and customers.
Establish and document method performance characteristics, including detection limits, accuracy, precision, stability, robustness, and measurement-system capability.
Collaborate with product-development teams to define analytical requirements for new materials, formulations, and products.
Evaluate, qualify, maintain, and troubleshoot analytical instrumentation such as GC, GC-MS, LC, IC, and FTIR.
Support analytical method change-impact assessments and contribute to cross-functional safety, readiness, and change-control reviews.
Prepare and maintain SOPs, work instructions, technical reports, method-validation documentation, measurement-system analyses, and verification or qualification records.
Provide technical guidance and training to laboratory colleagues on instrumentation, methods, data interpretation, documentation, and safe laboratory practices.
Support global analytical-development programs and collaborate with R&D teams, manufacturing engineers, quality partners, and external laboratories.
Promote a strong safety culture and maintain audit-ready laboratory practices while handling chemicals and working in laboratory and cleanroom environments.
Travel approximately 10% to 20%, including internationally.
