Upstream Process Development, Scientist / Senior Scientist

Some roles ask you to follow a process. This one asks you to shape it. At Zoetis, we're advancing the science of animal health-and we're looking for a scientist or engineer who can run bioreactors, think in models, and turn data into decisions. At the junction of upstream bioprocess development and modern analytics, you'll own study design with DoE, translate CFD into practical scaling and control, and explore multivariate analytics and pragmatic models to drive gravitydefying yields and process improvements. You'll partner across functions by listening well, learning quickly, and communicating clearly to deliver decisions and solutions. If you're ready to take ownership, share success with teams that value clear thinking, and accelerate your career in a space where science meets purpose, we'd love to meet you. Responsibilities: • Design, run, and interpret mammalian cell culture experiments in shake flasks and bioreactors for monoclonal antibodies and proteins • Apply DoE, statistical models, and scaleup principles to optimize processes • Design, execute, and translate CFD modeling into actionable scaling and control strategies • Champion multivariate analyses and modeling (e.g., PCA, timeseries analytics), and explore mechanistic models and hybrid/ML approaches where they add value • Leverage digital tools and data systems to improve process understanding and decisionmaking • Collaborate across upstream, downstream, formulation, and analytical teams • Document work in electronic lab notebooks and author highquality technical reports • Support tech transfers and regulatory filings with clear, traceable documentation • Drive innovation by evaluating new bioprocess technologies and modeling approaches to improve workflows Basic Qualifications: • Biochemistry, Molecular Biology, Biotechnology, Chemical/Biological/Biomedical Engineering, or related field. • BS and 4-7+ years industry experience, or • MS and 1-3+ years industry experience, or • PhD with relevant research and/or 0-3+ years industry experience Preferred Qualifications: • Strong upstream bioprocess foundation: cell culture and bioreactor operation (fedbatch, perfusion) • Scale-up/scale-down fluency and mass transfer fundamentals • DoE and MVDA literacy; experience with statistical tools a plus • CFD literacy with applied impact; handson experience a plus • Familiarity with scientific computing and data analysis tools and languages; capacity to interpret and adopt quickly • Exposure to mechanistic/kinetic modeling (e.g. Monod growth kinetics) and practical ML • Clear, firstprinciples reasoning; can explain assumptions and design validation experiments • Success bridging bench science, process engineering, and data science; strong communication and organization Full time Regular Colleague Any unsolicited resumes sent to Zoetis from a third party, such as an Agency recruiter, including unsolicited resumes sent to a Zoetis mailing address, fax machine or email address, directly to Zoetis employees, or to Zoetis resume database will be considered Zoetis property.
