This role is well suited for candidates with experience in protein therapeutics, biologics discovery, enzyme engineering, antibody engineering, or related pharma/biotech protein platforms who want to bring advanced protein engineering approaches into agricultural innovation. The Protein Engineering Scientist will play a key role in advancing trait discovery and development by applying modern protein engineering approaches, including library design, screening, directed evolution, and high-throughput design-build-test-learn workflows , to deliver impactful solutions aligned with R&D and business strategies. This position will work in a highly collaborative, multidisciplinary environment, partnering closely with discovery, analytical, and development teams to accelerate portfolio progression while maintaining strong scientific rigor, data quality, and operational excellence. This role will be on-site at our Corteva Seed Global Business Center located in Johnston, IA. Responsibilities - What You'll Do: Design, engineer, and optimize protein variants to improve activity, specificity, stability, expression, and overall developability. Apply biochemistry, protein structure-function knowledge, and molecular design principles to solve protein performance challenges. Develop and execute protein engineering strategies using approaches such as directed evolution, library design, mutagenesis, and screening/selection workflows. Execute protein expression, purification, and characterization workflows using recombinant systems and analytical techniques. Interpret biochemical, biophysical, and functional data to guide protein engineering strategy and next-step designs. Partner with cross-functional teams to advance proteins from early discovery through optimization and development decision points. Contribute to development and continuous improvement of protein engineering platforms, screening workflows, and automation capabilities. Maintain high standards of scientific rigor, reproducibility, data quality, and documentation. Support generation of high-quality data packages and reagents for research, technology, and development milestones. Stay current with emerging protein engineering and analytical technologies and help translate external innovation into internal capability building. Qualifications and Experiences- What You'll Need: Ph.D. (or equivalent experience) in biochemistry, protein engineering, structural biology, molecular biology, chemical biology , or a related field. Strong background in protein biochemistry and understanding of protein structure, stability, folding, and mechanism/function relationships. Hands-on experience in protein engineering , including one or more of the following: directed evolution display technologies (phage, yeast, ribosome, mRNA, or related platforms) library design and screening/selection rational or semi-rational protein design Experience with recombinant protein expression and purification workflows. Experience applying biochemical and analytical methods to characterize proteins, such as LC/MS, HPLC, ELISA, SDS-PAGE, binding assays, or biophysical characterization methods. Strong data analysis skills and ability to use experimental data to drive decisions and iteration cycles. Demonstrated ability to work effectively in a collaborative, team-based R&D environment. Strong written and verbal communication skills with a high level of scientific rigor and attention to detail.
