You will work closely with colleagues from various research groups, managing both routine workflows and complex troubleshooting to maintain a world-class cell repository.

POSITION RESPONSIBILITIES

• Cell Line Management: Direct the procurement, onboarding, expansion, storage (cryopreservation), and distribution of all mammalian cell lines to support downstream oncology and immuno-oncology studies.

• Mammalian Cell Culture Maintenance: Cultivate and maintain both existing cell lines and newly onboarded lines, focusing heavily on sterile cell culture techniques for transformed/immortalized human and murine cell lines.

• Quality Control & Inventory: Execute regular, rigorous QC processes to ensure highly accurate cell inventory tracking, contamination-free cultures, and efficient completion of all Central Cell Bank distribution requests.

• Audit & Regulatory Readiness: Maintain precise, timely, and complete documentation and records in electronic laboratory notebooks (ELNs) to support compliance audits and IND filing purposes.

• Excellent written, oral, and presentation skills with experience providing clear weekly updates to management and key stakeholders

• Experience in a fast-paced and highly collaborative team environment

PREFERRED QUALIFICATIONS

• Experience working within a centralized cell repository, cell banking core, or high-throughput cell processing facility.

• Experience troubleshooting challenging cell culture properties (e.g., optimizing post-thaw viability, handling clumpy suspension cell lines, and executing standardized dissociation protocols).

• Familiarity with automated cell counters, liquid handling systems, or automated incubation platforms.

PHYSICAL/MENTAL REQUIREMENTS

• Lifting of up to 30 pounds, frequent standing, walking, bending, and sitting at biosafety cabinets or lab benches.
