QC Chemist

Job Description

The QC Chemist works in a quality control laboratory within a pharmaceutical and specialty chemical manufacturing environment in the Milwaukee area. This role focuses on release and in-process testing of raw materials, intermediates and finished API products using a wide range of analytical instrumentation. The QC Chemist interprets chromatography data, manages analytical documentation in compliance with GMP requirements, and contributes to method and analytical development in a growing, expansion‑focused organization.

• Perform release and in‑process testing of raw materials, intermediates, test materials and finished API products in accordance with written methods and procedures.
• Follow all applicable procedures, specifications and test methods, ensuring full compliance with internal and regulatory requirements.
• Execute wet chemistry and analytical chemistry techniques to support quality control activities.
• Operate and utilize laboratory instrumentation, including HPLC, GC, FTIR, UV‑Vis, Karl Fischer (KF), IC and a soon‑to‑be‑installed ICP‑MS, to perform routine and specialized analyses.
• Interpret chromatography data and other analytical results, using data management systems such as Chemstation or Chromeleon where applicable.
• Assess whether materials meet specifications for release and document decisions clearly and accurately.
• Perform and review critical and complex calculations to support analytical testing and data evaluation.
• Prepare and standardize volumetric solutions to support routine and non‑routine testing.
• Clearly document all GMP activities accurately and legibly, maintaining complete and compliant laboratory records.
• Perform routine maintenance and basic troubleshooting on QC instrumentation to ensure reliable operation.
• Review data calculations for validation activities and ensure accuracy of analytical results.
• Provide information and documentation responses in cases of customer complaints or returns, supporting investigations and resolutions.
• Write procedures, test methods, protocols, reports and material specifications to support laboratory operations and continuous improvement.
• Support a culture of consistent compliance by participating in training, providing guidance and reviewing procedures as needed.
• Meet deadlines and testing schedules established by quality control leadership.
• Participate in a structured training process, progressing from observing tests to performing tests under supervision to independently executing tests.
• Handle laboratory supplies such as columns, liners, and septa and ensure proper setup and use of analytical equipment.
• Lift up to 25 pounds as needed to handle materials, reagents and equipment in the laboratory.

• Bachelor’s degree in a science discipline such as Chemistry, Biochemistry or Biology.
• 2–3 years of experience as a chemist in an industrial setting.
• Hands‑on experience with HPLC and GC in a quality control or analytical laboratory environment.
• Proficiency with laboratory instrumentation, including HPLC, GC, FTIR, UV‑Vis, Karl Fischer (KF) and IC.
• Ability to interpret and review analytical and chromatographic data accurately.
• Strong competency in performing and verifying critical and complex calculations.
• Experience working under GMP or similar regulated quality systems, with the ability to document activities clearly and legibly.
• At least 2 years of experience using Excel for data analysis, reporting and documentation.
• Capability to prepare and standardize volumetric solutions and perform wet chemistry techniques.
• Ability to write clear and concise procedures, test methods, protocols, reports and material specifications.
• Capacity to perform routine maintenance and basic troubleshooting on QC instrumentation.
• Ability to assess whether materials meet specifications for release based on analytical results.
• Physical ability to lift up to 25 pounds as part of laboratory duties.

• Experience with data management systems such as Chemstation or Chromeleon.
• Familiarity with NMR and broader analytical chemistry techniques.
• Experience with API, flavor and fragrance or specialty chemical environments.
