CMC Director (Chemistry, Manufacturing, and Controls Director)

Most weeks in this role move across process development, manufacturing scale-up, analytical methods, and the regulatory documentation that ties it all together. You're leading scientists and engineers across formulation, manufacturing, and analytical work, reviewing tech transfer plans, working through deviations and investigations, and authoring or reviewing the CMC sections of regulatory submissions. The cadence shifts dramatically around major regulatory milestones.

A common surprise is how much of the role is regulatory writing and review rather than bench science. Many find that a single missing piece of documentation can hold up an IND, BLA, or NDA submission for weeks, and that the technical decisions made early carry through every subsequent regulatory interaction. Vendor and CMO relationships tend to be a permanent management challenge in the increasingly outsourced production environment.

People who find satisfaction in the seam of science, manufacturing, and regulatory rigor tend to thrive. The role often suits those who can hold technical depth across chemistry and manufacturing while writing for FDA, EMA, and PMDA reviewers, and who can navigate the cross-functional pressure that builds toward filing dates. The cost is typically the documentation burden and the reality that elegant science still has to survive regulatory review.
