• Independently process analytical results and communicate findings to appropriate team members.
• Assist with analytical troubleshooting and instrument maintenance.
• Collaborate with experienced chemists and cross-functional teams to resolve technical challenges.
• Develop proficiency across analytical instrumentation and laboratory techniques.

Analytical Chemist II

At this level, you will take greater ownership of analytical projects, independently develop and validate methods, and provide technical support to other team members.

• Independently develop, optimize, validate, and transfer analytical methods.
• Evaluate complex analytical data and review peer-generated results for accuracy and completeness.
• Troubleshoot analytical methods and instrumentation with minimal supervision.
• Independently establish scientifically justified acceptance criteria for analytical method verification and validation protocols.
• Manage analytical priorities and project timelines to meet business needs.
• Contribute technical expertise to investigations, method improvements, and cross-functional problem-solving initiatives.

What We're Looking For Education & Experience

• Bachelor's degree in Chemistry, Biochemistry, Biology, or a related scientific field required.
• Master's degree or Ph.D. in Analytical Chemistry or a related field preferred.
• Relevant industry experience in analytical chemistry, method development, validation, or troubleshooting.

Candidates will be considered for either level based on their qualifications.

Analytical Chemist I

• Generally 1–3 years of relevant industry experience with a bachelor's degree.
• Demonstrated experience with analytical testing, instrumentation, and method verification or validation.
• Foundational experience troubleshooting analytical methods and interpreting laboratory data.

Analytical Chemist II

• Generally 3+ years of relevant industry experience with a bachelor's degree, or an appropriate combination of advanced education and experience.
• Demonstrated ability to independently develop, optimize, and validate analytical methods.
• Strong technical proficiency across multiple analytical instruments and techniques.
• Experience reviewing analytical data, troubleshooting complex issues, and supporting method transfers.

Technical Skills & Qualifications Analytical Instrumentation Proficiency

• Analytical Chemist I: Demonstrated proficiency with at least one primary analytical instrument, such as LC-DAD, GC-FID, or GPC/SEC with RI detection, along with one or more supporting analytical techniques.
• Analytical Chemist II: Demonstrated proficiency with at least three primary analytical instruments, including experience with more complex technologies such as LC-MS, GC-MS, NMR, or ICP-MS, and at least five supporting analytical techniques. Must be capable of independently troubleshooting complex analytical challenges.

Regulatory & Compendial Knowledge

• Analytical Chemist I: Knowledge of applicable USP, ICH, and other compendial guidelines related to analytical method verification and validation.
• Analytical Chemist II: Demonstrated ability to independently apply USP, ICH, and other applicable compendial guidelines to establish scientifically justified acceptance criteria for analytical method verification and validation protocols.

Additional Technical Qualifications

• Hands-on experience with analytical instrumentation and supporting techniques such as UV-Vis, FTIR, Karl Fischer, titration, pH, viscosity, or thermal analysis.
• Understanding of analytical method development, validation, verification, and data interpretation.
• Familiarity with ISO 9001, ISO 13485, or FDA GMP-regulated laboratory environments.
• Experience with analytical software such as ChemStation/OpenLab, Empower, or laboratory information management systems (LIMS).
• Strong analytical thinking, problem-solving, documentation, and communication skills.
• Ability to collaborate effectively with cross-functional teams while managing multiple priorities.
• Proficiency with Microsoft Word, Excel, and PowerPoint.
