This is a highly technical, high-autonomy role with direct impact on getting real treatments to patients.
Position DescriptionThe Opportunity- Provide engineering leadership for small-molecule drug product manufacturing process development and optimization to facilitate process transfer to CDMOs and scale-up.
- Lead equipment engineering and operations at drug product CDMOs, including technology transfer, CTM production, process troubleshooting, QBD, DOEs and PAR studies, registration batch production, and process validation.
- Coordinate with CDMOs and Nurix QA, Chemical Development, and Global Supply Chain functions to ensure timely manufacture and release of DP lots.
- Partner with Nurix Chemical Development and Analytical Development & Quality Control to identify critical process parameters of associated equipment and facility, and overall control strategies.
- Ensure adherence to applicable regulations including FDA, EMA, ICH, GCP, GMP and Nurix policies and procedures.
- Provide Person-In-Plant support for drug product manufacturing and ongoing performance monitoring of key facility and operational KPIs across manufacturing sites, including schedule adherence, batch performance, deviation trends, and inspection readiness.
- Support operational execution related to equipment scheduling, manufacturing, and coordination, supporting both clinical and commercial production requirements.
- Write and review CMC sections of regulatory filings, including INDs, IND amendments, and NDAs.
- Ensure all equipment trains at CDMOs are properly qualified, maintained, and operating at optimal performance to support Nurix manufacturing operations.
- Provide technical mentorship and guidance to scientists and engineers.
What You'll Bring- Ph.D. in chemical engineering or a related field with at least 8 years (M.S. with 12 years, or B.S. with 16 years) of industrial, late-phase, small-molecule drug product development experience.
- Extensive knowledge and experience in GMP oral solid dose form manufacturing (spray drying, tableting, and encapsulation), characterization, process development, equipment evaluation/selection, scale-up, and process validation.
- Extensive third-party drug product CDMO management experience, including tech transfer activities, QBD and DOE studies, clinical supply production, registration batch production, and commercial launch activities.
- Knowledge and understanding of product/packaging interactions, barrier properties, stability, global pharmaceutical packaging regulations, and package testing.
- In-depth knowledge of relevant cGMP, ICH, FDA, and EMA guidelines.
- Proven track record of effective internal and external collaboration.
- Excellent oral/written communication skills, interpersonal skills, and problem-solving abilities.
- Ability to multi-task, manage conflict, and work in a fast-paced environment.
- Ability to travel up to 25% of time.
