Job Description

BPR&D within our Company's Research Laboratories is on a mission to rapidly deliver biotherapeutics to patients by efficiently developing innovative, robust manufacturing processes and technologies. To achieve this, we work closely with colleagues in Discovery, Pre-clinical, Early Development, Analytical, Formulation, and Commercial Manufacturing while providing an inclusive environment for all. Beyond process development for pipeline biologics, we innovate and build next generation biomanufacturing technologies. Examples include investments for development of continuous manufacturing, green and sustainable processes, and proprietary technology platforms. We actively publish and engage with the scientific community to influence the field.

As a Senior Principal Scientist you will have the opportunity to influence the future strategy and direction of our Company's Downstream Processing of Biologics. You will work with an immensely creative and collaborative team of scientists and engineers to design purification processes while developing technical strategies related to downstream processing for drug candidates in early- and late-stage development.

Responsibilities include but are not limited to:

  • As an impactful contributor, shape and realize innovation across the Biologics’ pipeline, strategy, and science

  • Advance the pipeline by leading cross-functional teams, from Research & Manufacturing, in a fast-paced, multidisciplinary environment

  • Participate in or lead 1) development of robust and scalable purification processes for biologics in different stages of clinical development, 2) process characterization and regulatory filings for successful commercialization

  • Advance downstream processes by improving efficiency and cost effectiveness through research and innovation, while assessing technologies and industry best practices

  • Collaborate with academia, industry, and vendors to drive development and early adoption of novel process technologies

  • Lead strategic initiatives; partner with senior leaders to set overall project strategy, and guide teams towards its execution

  • Conceptualize, plan, and execute projects with effective organizational, prioritization and problem-solving skills

  • Stay abreast of scientific and regulatory landscape; actively present (premier conferences), publish (peer-reviewed journals) and patent

  • Represent BPR&D as a downstream bioprocess expert in internal, cross-functional project teams and external conferences/consortia

  • Mentor and actively share expertise; guide career development; build strong, collaborative teams

  • Champion compliance and safety; promote a culture of inclusion

MINIMUM EDUCATION REQUIREMENTS:

  • Ph.D. with 9+ years, MS with 11+ years, or BS with 15+ years of industry experience and background in Chemical/Biochemical engineering, or a related field

REQUIRED EXPERIENCE, SKILLS, AND COMPETENCIES

  • Strong fundamental knowledge and subject matter expertise in downstream processing of biologics, recent advances, and challenges in the field

  • Expertise in independently conducting and directing the design, execution, analysis, and documentation of all stages of purification process development

  • Track record of accomplishments in downstream bioprocessing with a history of peer-reviewed publications and presentations

  • Knowledge of biologics CMC development

  • Adaptability and agility to prioritize and deliver complex objectives, often on tight timelines, in a rapidly changing environment

  • Experience and aptitude to lead, work, and collaborate in internal and external cross-functional, matrixed teams

  • Action-oriented, mindset for creativity; ability to take initiative, innovate, iterate and problem-solve

  • Demonstrated commitment to coach and mentor staff to maximize talent development and utilization

  • Leadership of CMC development teams

  • Excellent interpersonal and communication skills

PREFERRED EXPERIENCE & SKILLS:

  • Continuous biomanufacturing integrated with process-analytical technologies

  • High-throughput experimentation, automation, and process control

  • Knowledge of protein expression, analytics, conjugation chemistry and formulation

  • Digital fluency including data-science, machine learning and artificial intelligence

  • Proficiency with biophysical, mechanistic and facility modeling; statistical analysis, and computational fluid dynamics
