Are you ready to turn recombinant protein design into therapies that change the way cancer is treated? In this laboratory-based role, you will deliver high-quality antigens that fuel our biologics discovery portfolio and help move promising ideas into the clinic. Your work will directly enable teams to evaluate novel modalities and make faster, better-informed decisions for patients. As a Senior Scientist in Protein and Cell Sciences, you will design, express, purify and characterize recombinant proteins that underpin antibody discovery and other biologics programs. You will use modern computational tools alongside rigorous experimental methods to ensure the proteins you produce behave as intended. Can you see your experiments influencing cross-functional strategy in real time? This is the bench where that happens.
Accountabilities
* Recombinant Antigen Design: Apply computational structural biology (including AlphaFold and ProteinMPNN) to design target proteins that are fit-for-purpose for discovery and development.
* Expression Vector Engineering: Design recombinant expression vectors using standard molecular biology techniques; optimize constructs for expression and stability.
* Protein Production: Express and purify recombinant proteins using bacterial and transient mammalian systems (E.coli, HEK, CHO), building robust, scalable methods and standard operating procedures that improve throughput and reproducibility.
* Functional Characterization: Develop and deploy assays to monitor protein expression, function and quality (e.g. SDS-PAGE, analytical SEC, ELISA, cell-based assays, OCTET), ensuring integrity and suitability for downstream applications.
* Data, Documentation and Insight: Make detailed observations, analyze data and interpret results; maintain rigorous electronic laboratory notebooks and databases to create a reliable evidence base for decision-making.
* Collaboration and Communication: Report and present findings to project teams and the department; contribute scientific judgment that shapes early- and late-stage therapeutic programs.
* Continuous Improvement: Troubleshoot experimental processes and apply automation in molecular biology and protein expression to reduce cycle times and increase consistency.
