"Bring hands-on regulatory judgment to AI that runs the registered life of a product."

About Cheiron

Cheiron is building AI software for regulatory lifecycle management in the pharmaceutical industry, and we are working with our first pilot customers. The platform keeps track of what is registered in each market (the approved state, commitments and conditions, and the filings needed to keep registrations current) and, when a manufacturing or quality change is proposed, works out what it means in each market for review by qualified regulatory staff. It also drafts and checks regulatory documents. Customers keep their own regulatory records, and their qualified staff make the formal decisions; Cheiron supports that work.

About the Role

You will work alongside AI that produces first drafts, assessments and checks. Your judgment decides what is right, and your work makes the system better. You will be the hands-on integral regulatory affairs expert on a growing Life Sciences team, responsible for regulatory correctness across the registered life of a product, from routine maintenance to the cases the guidelines do not settle.





You own the work for your assigned accounts within agreed scopes. Our Associate Director of Regulatory Affairs is the team's senior regulatory authority: you document hard cases, propose a position and elevate, and the Associate Director makes the final call. Expect roughly half your time on customer delivery and half on reusable content, validation and product improvement. At Senior Manager level you also structure ambiguous cross-functional work and lead difficult customer discussions; level reflects demonstrated scope and independence.

This role reports to the Head of Life Sciences. It is an individual contributor role with no direct reports.
