Job Description

Our Engineers support internal and external manufacturing operations remain operational, continuously improve and innovate. With our extensive range of facilities and environments, our Engineers have opportunities across many diverse areas including Biological, Chemical, Automation, Capital Projects, Maintenance, Safety, Process Development, Technical Services, Utilities and Validation.

As part of the Manufacturing Division, the Bioprocess Drug Substance and Commercialization (BDSC) department provides technical process leadership and laboratory capabilities in support of late stage pipeline and commercial manufacturing processes for large molecule products, including biologic and vaccines. Within BDSC Bioprocess Engineering, we partner across areas of the or Company Manufacturing Division and cross-divisionally with our Research & Development Division with the ultimate goal of delivering innovative products to patients.

The primary responsibility of the engineers and scientists within the Bioprocess Engineering group is to deliver Stage 2 validation requirements for novel, pipeline products to the intended commercial manufacturing sites. BDSC Process Engineering supports various commercialization activities, including technology transfer to internal and external manufacturing sites, process validation, authoring of regulatory submissions, manufacturing investigations and trend evaluations, process enhancements, and next generation process (i.e., post approval) characterization. Through process engineering, we ensure that our company’s large molecule drug substance processes can be scaled up or scaled out into the manufacturing facilities with our respective partners.

Under the general scientific and administrative direction of a Director in Downstream Process Engineering and working in conjunction with internal and external partners, the Associate Principal Scientist will support late stage and commercial downstream tech transfer, large scale process optimization, characterization, and validation of purification processes for multiple indications. This person will demonstrate scientific, experimental, and tech transfer skills focusing on downstream processing.

Technical scope:

· Leads project team focusing on late-stage clinical process characterization, technology transfer and validation of biopharmaceutical molecules with line-of-sight for licensure and commercialization. Drive team’s project milestones and deliverables.

· Responsible for the optimization of scalable, efficient, high-yielding, high-purity, and cost-effective downstream purification processes that are comparable to leading stability batches.

· Drive technical innovation for the continuous improvement of platform technologies for recovery and purification of novel therapeutic programs including utilization of internal resources/expertise and external vendor collaborations.

· Establish and implement appropriate strategies for stage 2 process validation, including strategies for mixing, resin/membrane reuse, and hold time studies.

· Responsible for manufacturing scale studies to support commercial process validation, characterization, and investigation evaluations, including studies performed either in-house or externally. Provides technical leadership for the design of experiments, data analysis and interpretation.

· Provides technical direction in the interpretations of trends observed in commercial process monitoring (e.g., statistical process control (SPC) and/or multivariate analyses (MVA)), and for further technical investigations and process changes that seek to drive improvements to yield and/or robustness.

· Primary focus will be on downstream processing, but with a working knowledge of the various aspects of product manufacture and functional area interdependencies, including cell culture, analytical, and drug product.

· Position will interact with and influence various functions across late-stage development and commercialization (i.e. process development, analytical, quality, technical operations, external manufacturing, regulatory, value chain management). Position will also lead functional area on cross-functional and cross-divisional teams.

· Authors required regulatory and technical documentation associated with process Tech Transfer, PPQ, and validation. Ensures that process/product are developed and documented according to standard company practices. Supports regulatory queries and inspections as required.

· Develop and mentor team and junior staff members for technical development

Education Minimum Requirement:

· B.S., M.S., or PhD in Chemical Engineering/Biochemical Engineering/Chemistry/Biochemistry/Biological Engineering/Biological Science with 8 years (for BS), 6 years (for MS), or 3 years (PhD) relevant experience.

Required Expertise and Skills:

· Technical expertise in purification of biopharmaceutical molecules, including laboratory models for chromatography and filtration systems. Expertise with downstream purification of biopharmaceutical molecules required, with an in-depth knowledge of preparative chromatography, tangential flow filtration, and virus retaining filtration desired. Demonstrated understanding of the fundamentals and/or modeling of unit operations is a plus.

· Expertise with technology transfer and scale-up of processes to pilot and manufacturing scales for biopharmaceutical manufacture.

· Excellent oral and written communication skills. Ability to effectively articulate understanding of process science, in order to drive decision making, impact assessments, design of studies, etc., in a multi-disciplinary team environment.

· Working knowledge of the requirements associated with site readiness for new product introductions and will be able to oversee teams through these requirements. Should have familiarity with GMP principles and regulations

Preferred Expertise and Skills:

· Technical operations expertise in the manufacture of biopharmaceutical molecules at the pilot- and/or commercial-scale is a plus.

· Expertise in late-stage process development, process characterization including viral clearance studies, process performance qualification and validation, site readiness, batch record reviews, authoring regulatory BLA sections and/or working with external contract organization for development and or manufacturing.

· Working knowledge of statistical methods for DOE design and data analysis (e.g., JMP or Design Expert software)

· End to end understanding around timelines and key deliverables associated with late-stage commercialization

· Working knowledge of statistical process control (SPC), multivariate analysis (MVA), and/or process analytical technologies (PAT) techniques for biopharmaceutical processes.

· Working understanding of analytical methods to characterize biopharmaceutical processes and /or US/EU regulatory requirements and / or working knowledge of cGMPs is a plus
