 Position 

Nurix Therapeutics seeks an experienced Scientist to join the Analytical Development and Quality Control group. The Scientist will conduct analytical method development and material characterization studies to inform drug substance and drug product development. They will also provide operational oversight at external CDMO/CTL partners, manage reference standards and impurity markers, collaborate in CMC risk management, and author technical reports.

In Nurix’s laboratories, the Scientist will characterize material attributes and impurities by high resolution mass spectrometric and multidimensional chromatographic techniques. They will determine impurity structures, characterize material stability, and elucidate mechanisms of degradation. They will employ state of the art QbD approaches to develop and troubleshoot chromatographic test methods to accelerate and derisk QC activities performed externally at CDMOs and CTLs. The Scientist will critically evaluate characterization data and communicate results in multidisciplinary teams.

The ideal candidate must have demonstrated expertise in mass spectrometry and hands-on experience with liquid chromatography. Hands-on experience with two-dimensional liquid chromatography is a plus.

This position is onsite at Nurix headquarters in Brisbane, CA.
