About the Role
We are seeking a Senior Project Manager, Biologics R&D to serve as project manager of record for our lead T-cell engager program, as it advances from late-stage research through development candidate nomination and IND-enabling studies. You will partner closely with the Program Team Lead, who owns program strategy and scientific direction, you will own program execution - the integrated plan, timelines, risk management, budget tracking, and the operational machinery that turns strategy into decisions and deliverables. The ideal candidate will have hands-on experience in biologics R&D, with the ability to own timelines, track deliverables, and partner closely with scientific leads to keep the program moving forward.
This is a role for an experienced antibody-biologics project manager who operates independently: you know the research-to-development transition firsthand, you can pressure-test functional timelines rather than transcribe them, and you drive teams to decision-ready data on schedule.
Key Responsibilities
Project Planning and Execution
- Own day-to-day planning and execution of the program, ensuring execution of key activities from late-stage research through IND-enabling work across research, nonclinical, CMC, and regulatory workstreams.
- Build and maintain project timelines that capture critical path, major milestones, dependencies, and deliverables.
- Partner with scientific leads and functional stakeholders to align on scope, priorities, resources and progress, pressure-testing functional timelines and assumptions against standard durations and failure modes for biologics early development (e.g., developability, cell line development, GLP toxicology).
Milestone Management & Decision Support
- Collaborate with scientific teams to define key project milestones, decisional experiments and translate into actionable, resource-informed timelines.
- Frame and compile project data, timelines, risks, value-realization, and trade-offs to support informed decision-making, including development candidate nomination criteria and go/no-go decision packages, framed early and driven to on-time delivery against the baselined plan.
