Senior RA​/Associate Scientist

If you’re a Senior Research Associate or Associate Scientist with hands‑on antibody discovery experience and a drive to advance new therapeutics, we’d love to hear from you!

Join Us at Oxford Biotherapeutics (OBT)

Oxford Biotherapeutics (OBT) is a clinical‑stage biotechnology company developing innovative antibody‑based therapeutics for the treatment of cancer. You will contribute directly to the pre‑clinical development of our immuno‑oncology pipeline.

Our proprietary OGAP® platform, the world’s largest cancer‑specific membrane protein library enables the discovery of novel, highly tumour‑specific antigens for first‑in‑class ADC, Bispecific T‑cell Engager (BITE®), and CAR‑based therapeutics. Our lead asset, OBT
076, is in Phase 1b clinical development, supported by a strong internal and partnered pipeline with leaders such as Roche, Boehringer Ingelheim, and Zymeworks.

The Antibody Discovery Research Associate will support early‑stage therapeutic and tool antibody programs by performing experiments that contribute to antibody generation using single B cell platforms, screening, and lead candidate selection.

The ideal candidate is highly organized, detail‑oriented, and comfortable working in a fast‑paced, collaborative research environment.

• Perform hands on antibody discovery work flows including cell culture, multi colour flow cytometry to sort and analyse rare immune cell populations.
• Develop, optimize and perform screening cell‑based functional assays.
• Characterize antibodies by performing Elisa, SPR, BLI (Octet), Western blot.
• Maintenance of cell lines, freezing, thawing, expansion.
• Perform molecular biology tasks like PCR, cloning, transfection, sequence analysis, RNA/DNA purification methods, gel extraction as needed.
• Ensure all experimental work complies with established protocols and SOP’s.
• Maintain accurate and detailed experimental records and record all experimental data into Electronic Notebook.
• Contribute to troubleshooting, optimization, and continuous improvement of discovery workflows
• Compiling and analysing data by Flow Jo, Graph Pad Prism, and Excel.
• Conduct analysis and effectively communicate results and present data at internal meetings.
• Collaborate with cross functional teams to align with project goals.
• Committed to fostering an inclusive, collaborative, and innovative research environment.
