The ideal candidate will demonstrate strong technical aptitude, careful attention to detail, and a commitment to animal welfare, compliance, and high-quality study execution. The Associate Scientist is expected to contribute as a dependable technical team member while building scientific understanding of oncology pharmacology and ADC-specific study requirements.

Position Responsibilities

• Conduct routine in vivo oncology study activities supporting ADC programs, including tumor measurements, body weight monitoring, clinical observations, dosing support, and sample collection.
• Assist with execution of xenograft, syngeneic, and other oncology models under established protocols and guidance from study leads.
• Support pharmacology studies evaluating ADC efficacy, tolerability, pharmacodynamic biomarkers, dosing schedules, and combination approaches.
• Prepare study materials, confirm dosing and sampling schedules, and ensure study activities are performed according to approved protocols and SOPs.
• Maintain accurate, timely, and compliant study records using approved electronic data capture and documentation systems.
• Communicate study observations, technical issues, animal welfare concerns, and timeline risks promptly to managers and study line leads.
• Collaborate with vivarium operations, project teams, pathology, bioanalytical, pharmacodynamic, and pharmacokinetic colleagues to support efficient study execution.
• Ensure all work is conducted in accordance with IACUC protocols, animal welfare expectations, biosafety requirements, and Pfizer internal policies.

• Ability to follow study protocols, dosing schedules, sample collection plans, and SOPs with precision and attention to detail.
• Basic understanding of oncology pharmacology concepts, including tumor growth, treatment response, tolerability monitoring, and pharmacodynamic endpoint collection.
• Strong organizational skills and ability to support multiple concurrent study activities under guidance from supervisors or study leads.
• Effective written and verbal communication skills and ability to work collaboratively within a multidisciplinary team.
• Applies technical skills to routine and moderately complex procedures while developing independence and troubleshooting capability.
• Demonstrates accountability for assigned tasks and contributes to team goals, study timelines, and quality expectations.

Preferred Qualifications

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