Position Description:

The Director, Bioconjugation Process is responsible for the process development and manufacturing of large molecule bioconjugates for biotherapeutics, with a focus on Antibody Drug Conjugates (ADCs).  The successful candidate will drive the CMC elements related to bioconjugation throughout the product life cycle.  The role requires technical expertise in conjugation chemistry, reaction processes and purification operations.  A familiarity with critically relevant areas such as analytical characterization, formulation, and the general CMC scope for biologics is also required.  In addition, the role requires a successful track record of carrying out development and manufacturing activities virtually, including a demonstrated ability to work effectively with CDMOs.

Position Requirements:

•    Subject Matter Expert in bioconjugation process development and manufacturing in support of CMC
•    Work closely with research function to understand relevant conjugation chemistries and transition bioconjugation process from research to CMC development.
•    Develop plan and lead process development and manufacturing of bioconjugation process and associated CMC requirements
•    Oversee development and technical transfer of processes between Third Parties (CDMOs and Partners)
•    Lead and manage CDMOs on behalf of Exelixis in the areas of bioconjugation development and manufacturing, including alignment and oversight on planning and budgetary activities
•    Partner with Exelixis CMC and Quality colleagues, and CDMOs, to support cGMP manufacturing within the Exelixis-CDMO quality systems
•    Lead efforts to identify and champion new chemistries and process technologies for bioconjugation
•    Work collaboratively with SMEs in other CMC areas such as formulation and analytical to develop sound, integrated plans for development and manufacturing
•    Define and manage technical projects across Exelixis and CDMOs with focus and urgency
•    Remain current on Health Authority guidance and expectations, and contribute to regulatory strategy and submissions

•    MS/MA in biochemistry, molecular biology, chemical engineering, biology, chemistry, or related degree and ten years related experience 
•    PhD in biochemistry, molecular biology, chemical engineering, biology, chemistry, or related degree and eight years related experience 
•    Equivalent combination of education and experience

•    Direct experience designing and implementing experiments to evaluate bioconjugation processes, including ADCs
•    Experience with ADC chemistry, reaction processes and purification methods 
•    Strong development experiences bringing biologics from Phase I through commercial, including experience in late-stage activities such as CMC risk assessments, process characterization and validation.
•    Demonstrated experience working with Contract Development Manufacturing Organizations (CDMOs) in North America, EU and Asia
•    Demonstrated experience and working knowledge of technical transfer for Biologics manufacturing (bioconjugations)
•    Experience with documentation of experiments, analyzing data, generating high-quality technical reports, and Quality/Regulatory information
•    Experience with Project Management (budgeting, timelines, resourcing, planning)
•    Additional experience with the development and manufacturing of recombinant biologics, and/or linker-toxins used in ADC production, is a plus.   
•    Experience in biologics related CMC regulatory activities and in the support of manufacturing quality for biologics molecules
