Apply if you can lead complex science and defend it with confidence. Your Typical Day

You’ll start onsite in Cherry Hill by checking in on active studies, key data trends, and any open quality-system items that need senior scientific judgment. Expect focused time reviewing chromatograms, calculations, and narratives for high-visibility deliverables, then short, direct discussions with scientists to align on technical approach and next steps. You’ll join client calls to clarify method strategy and provide clear scientific rationale, and you may step into an audit or inspection discussion as the technical voice for the lab. Between reviews, you’ll set aside time to strengthen technical standards, guide training, and keep long-running programs moving without surprises.
