Job Title: R&D Chemist (Chemist II or Chemist III)

Job Description

This role offers the opportunity to serve as an R&D Chemist at either a Chemist II or Chemist III level, depending on experience. You will work closely with a small, collaborative team to perform HPLC and other solid dosage testing on nutraceutical products, lead or support finished product stability studies, and contribute to method development and small bench-scale formulation. The position combines hands-on analytical work with lab coordination tasks such as ordering, documentation, and preparation of samples for external contract laboratories.

Responsibilities

• Work alongside another chemist to perform HPLC assays and other solid dosage testing, including disintegration and weight discrepancy testing, primarily on finished nutraceutical products.
• Run approximately 3–4 HPLC assays per week, working primarily with Shimadzu HPLC instrumentation on small molecule analyses.
• Conduct finished product stability studies as a primary responsibility, including planning, execution, and documentation of stability study interval testing.
• Perform routine analytical testing using HPLC and wet chemistry techniques in a laboratory environment.
• Prepare and organize samples and associated paperwork for submission to external contract laboratories, ensuring accuracy and completeness.
• Enter analytical data and stability study results into LIMS and other electronic software systems, maintaining fully electronic documentation (no paper lab notebooks).
• Support method development and validation activities and assist with systems improvements under appropriate supervision.
• Assist with small bench-scale formulation work and small-scale stability studies as needed.
• Order and manage laboratory reagents, consumables, and supplies, planning ahead for upcoming testing and stability needs.
• Coordinate ordering and purchasing for the lab for the coming months, including tools and materials needed for stability interval testing.
• Prepare and send equipment out for calibration and ensure instruments are maintained in good working order.
• Follow hazardous waste handling requirements and assist with hazardous waste disposal in accordance with lab procedures.
• Maintain general lab cleanliness, organization, and a safe working environment, including routine cleaning tasks.
• Complete detailed, accurate documentation for all testing and stability work in compliance with internal quality and, as applicable, GMP expectations.
• Contribute to product development and other non-routine tasks based on experience level and project needs.
• For Chemist III level: take on more administrative responsibilities in the lab, including overseeing lab ordering, coordinating sample shipments to contract labs, and managing stability interval tools.

Essential Skills

• Bachelor’s degree minimum, preferably in Chemistry or a closely related scientific discipline.
• Approximately 5–10 years of experience as a chemist in a laboratory environment (quality or R&D) within nutraceutical, pharmaceutical, or similar industries.
• Hands-on experience performing HPLC assay testing in a lab environment, preferably in an R&D setting, but quality control lab experience is also suitable.
• Proficiency with analytical chemistry techniques and small molecule HPLC methods.
• Experience working with Shimadzu HPLC instrumentation or similar systems.
• Solid dosage testing, including disintegration and weight discrepancy testing.
• Experience in quality control or R&D environments, ideally under GMP or similar regulated conditions.
• Familiarity with wet chemistry techniques used in analytical and stability testing.
• Ability to conduct and document finished product stability studies and interval testing.
• Strong organizational skills with the ability to plan ahead, manage multiple tasks, and maintain consistent, efficient workflows.
• Ability to work independently, manage time effectively, and maintain a high level of attention to detail in documentation and testing.
• Comfort with fully electronic documentation systems, including LIMS and related software.

Additional Skills & Qualifications

• Experience in the nutraceutical and/or pharmaceutical industries.
• Experience working specifically with finished products is a significant plus.
• Experience with botanicals and botanical-based products is a strong plus.
• Familiarity with hazardous waste handling and disposal requirements.
• Experience supporting method development and validation activities.
• Exposure to or experience with small bench-scale formulation work.
• For Chemist II: approximately 5 years of experience, with a focus on routine HPLC work and some physical testing in the lab.
• For Chemist III: approximately 5–10 years of experience, with readiness to handle broader administrative and coordination responsibilities in the lab and flexibility on degree type.
• Ability to collaborate effectively in a small team environment and communicate clearly with colleagues and external labs.
