Senior Associate Scientist, Immuno-Oncology

The Oncology & Immuno-Oncology group is seeking an exceptional Senior Associate Scientist to join a high-performing team dedicated to advancing next-generation bispecific antibodies for solid tumor indications. This role is best suited for a scientifically rigorous, highly driven individual who thrives in a fast-paced, translational research environment where high-quality experimental data directly supports clinical advancement.

In this role, you will contribute to the development and evaluation of novel bispecific antibody therapeutics, working at the intersection of tumor biology and immune modulation. You will collaborate closely with cross-functional teams and generate robust, reproducible datasets that inform program progression from preclinical development toward clinical studies.

This position offers the opportunity to work on cutting-edge approaches in cancer immunotherapy with clear line-of-sight to clinical application, while gaining increasing exposure to experimental design, data interpretation, and program-level scientific discussions. The ideal candidate is motivated, organized, detail-oriented, and thrives in a fast-paced, team-driven environment. Experience with tumor models and mammalian cell culture is highly desirable.

As an Associate Scientist in the immune-oncology group, your typical day might include:

• Execute well-designed in vivo studies to evaluate novel bispecific antibodies, including mouse handling, dosing (IP, IV, subcutaneous), and blood/tissue collection

• Perform ex vivo immune profiling (e.g., flow cytometry, ELISA, MSD) to characterize pharmacodynamic response and mechanism of action

• Process tissues and tumors for immune cell isolation and downstream analysis

• Generate high-quality, well-documented datasets suitable for inclusion in internal reports supporting program advancement

• Collaborate closely with multidisciplinary teams to ensure alignment of experimental design with program needs

• Present findings in group and cross-functional meetings, contributing to ongoing scientific discussions

This role may be for you if you:

• Are energized by working in a science-driven, collaborative environment focused on impactful therapeutic development

• Bring strong attention to detail, organization, and commitment to experimental rigor and reproducibility

• Are adaptable and eager to learn new techniques and contribute across multiple workflows

• Are motivated by the opportunity to contribute to the advancement of novel therapeutics toward the clinic

• Present findings in group and cross-functional meetings, contributing to ongoing scientific discussions

To be considered, you must meet the following:

• B.S./M.S. with 2-3yrs relevant experience in oncology, immunology, or related field

• Experience with mouse handling and in vivo tumor models strongly preferred

• Experience with cell culture, flow cytometry, and/or immunoassays (ELISA, MSD) is highly desired

• Demonstrated ability to generate high-quality data with strong attention to detail

• Ability to work independently while contributing effectively in a team environment

• Strong analytical skills and clear communication of scientific findings
