Senior Director, Analytical Development and Quality Control

SENIOR DIRECTOR, ANALYTICAL DEVELOPMENT & QUALITY CONTROL

At Day One, we are focused on advancing first- or best-in-class medicines for childhood and adult diseases with equal intensity. We were founded to address the lack of new therapies resulting from the traditional drug development model, that has left children with cancer and their families waiting too long for new, life-changing treatments. Our aim is to accelerate better, targeted treatments so patients of any age can look forward from ‘day one’ to the future they’ve envisioned.

POSITION SUMMARY:   

The Senior Director of Analytical Development & Quality Control (QC) will lead the strategy and execution of analytical development and QC activities across biologics, small molecules, and antibody-drug conjugates (ADCs), supporting both pipeline programs and the commercial product OJEMDATM.

This role will define the analytical control strategy from early development through commercialization, ensuring robust product characterization, validated methods, and global regulatory compliance. Operating within an outsourced model, the Senior Director will oversee CDMOs/CMOs, ensuring scientific rigor, data integrity, and quality standards across release and stability testing programs. This position will report to the Vice President, CMC Technical Operations.                                                                                             

As part of the CMC Technical Operations leadership team, this leader will drive innovation, inspection readiness, and cross-functional alignment with Quality Assurance, Regulatory, and Supply Chain.

This position has the potential to be fully remote. Occasional travel of 10% will be required for in person meetings.
