Scientist​/Sr​/Principal Scientist, ADC & Translational Research

Oxford Bio Therapeutics (OBT) is a clinical stage oncology company with a pipeline of immuno-oncology and antibody-drug conjugate-based therapies. OBT's IO discovery process provides unique insight into the cancer-immune cell synapse and has identified several novel IO candidates for cancer therapy. Discovery of novel tumour antigens and immune cell surface proteins at OBT is performed using the proprietary Oxford Genome Anatomy Project (OGAP®) database.

OBT currently has one ADC in phase 1b clinical trials in collaboration with Menarini. OBT is a dynamic, growing, international biotechnology company based in Oxford, UK, and San Jose, CA. For further information, please see

Purpose of the Role

We are seeking a Scientist/Sr/Principal Scientist experienced in ADC and Translational Research to join our team. This person will contribute directly to OBT’s Oncology ADC pipeline and drive innovation with cancer biologists, immunologists, and protein and antibody discovery scientists to develop first-in-class ADC therapies. They must be a team player, strategic thinker, and effective communicator to accomplish the company’s goals in the fast-paced and dynamic industry environment.

The Antibody drug conjugate (ADC) & Translational Science team is at the forefront of developing and delivering novel targeted therapies for the unmet needs to transform the lives of cancer patients. We identify, validate, and advance the discovery of new ADCs through comprehensive biological evaluations of tumor-associated antigens, their targeting antibodies, and linker payloads, as well as vigorous preclinical studies. As we drive toward the next generation of therapeutics, we seek an energetic, highly motivated, and interactively proficient scientist to perform hands-on experiments to advance projects and/or development decisions.

• Design and execute key in vitro and ex vivo experiments independently to identify and characterize novel tumor-associated antigens and evaluate ADCs with different payloads and DARs that inform and enable project progression.
• Utilize diverse cutting-edge molecular and cell-based techniques including antibody internalization rate analysis, antigen recycle rate analysis, antigen density analysis, various effector-dependent and independent cytotoxicity assays in high throughput and real time manners, ELISA, multiplex cytokine immunoassays, immunogenic cell death (ICD), quantitative multi-colored flow cytometry analysis (Flow Jo), Graph Pad Prism, CyTOF, gene set enrichment analysis, bioanalytical pharmacokinetic (PK) and pharmacodynamic (PD) assays, toxicity profiling screening, immunogenicity, ADA evaluation.
• Collaborate cross-functionally with discovery, bioinformatics, protein sciences, and translational teams to drive ADC candidate selection and optimization.
• Conduct and interpret binding affinity assays, stability studies, and functional characterization of engineered antibodies.
• Expand in-house capabilities for ADC toxicity by implementing new techniques and cutting-edge technologies.
• Apply ML/AI approaches to guide antibody sequence optimization, develop predictive models, and analyze large datasets (e.g., sequence-function relationships, develop ability metrics).
• Cultivate a culture of scientific excellence, urgency, critical thinking, and continuous learning.
• Independently devise, execute, and analyze hypothesis-driven translational research experiments to identify PD biomarkers, mechanisms of sensitivity and resistance and test novel drug-combinations to further advance the OBT ADC pipeline.
• Lead programs by executing lead optimization strategies and driving discovery goals.
• Prepare patent applications and publish impactful research.
• Supervise, mentor and train less experienced employees.

Please note the roles and responsibilities for the position include but are not limited to the above.

• PhD in cancer biology, immuno-oncology, pharmacology, pharmaceutical sciences, or related discipline. Master’s degree with 6-10+ years of experience or bachelor’s degree with 8-12+ years of experience in the biopharmaceutical industry.
• Post-doctoral training (4+…
