Nice To Haves

• Experience supporting ADC, targeted therapy, immuno-oncology, or oncology combination studies.
• Familiarity with ADC pharmacology concepts, including target-antigen expression, payload activity, linker stability, exposure-response relationships, and tolerability monitoring.
• Experience with necropsy, tissue or blood collection, biomarker sample processing, or ex vivo endpoint workflows.
• Experience executing ex vivo or in vitro methods such as flow cytometry, cell-line assays, and molecular-biological or biochemical procedures.
• Familiarity with electronic in vivo study-management systems such as Studylog or similar platforms.
• AALAS certification or equivalent animal-care and use training.

Responsibilities

• Execute in vivo oncology studies using models such as human cell line-derived, patient-derived xenograft, and syngeneic models, with minimum guidance from study leads.
• Perform in vivo procedures including tumor measurements, body-weight monitoring, test-article administration by IV, PO, subcutaneous, and intraperitoneal routes, clinical observations, and sample collection.
• Perform routine in vitro tissue-culture procedures.
• Support pharmacology studies evaluating efficacy, tolerability, pharmacodynamic biomarkers, dosing schedules, and combination approaches.
• Prepare study materials, confirm dosing and sampling schedules, and conduct study activities according to approved protocols and SOPs.
• Maintain accurate, timely, compliant study records in approved electronic data-capture and documentation systems.
• Promptly communicate study observations, technical issues, animal-welfare concerns, and timeline risks to managers and study line leads.
• Collaborate with vivarium operations, project teams, pathology, bioanalytical, pharmacodynamic, and pharmacokinetic colleagues.
• Conduct work in accordance with IACUC protocols, animal-welfare expectations, biosafety requirements, and Pfizer policies.

Benefits

• 401(k) plan with Pfizer matching contributions and an additional Pfizer Retirement Savings Contribution.
• Paid vacation, holiday, and personal days.
