About this opportunity

Job Description

Our Company is currently seeking an exceptional scientific leader for our Discovery Process Chemistry (DPC) group at our Boston, MA site.

The core responsibility of the successful candidate will be to lead a team of scientists in the development of innovative solutions to complex chemistry problems across a diverse portfolio of projects and modalities in the discovery phase, from lead identification through candidate selection, with the goal to apply these solutions to facilitate medicinal chemistry research by overcoming synthetic bottlenecks, streamlining SAR analogue synthesis, and providing access to novel chemical space.

The position is also responsible for defining scalable synthetic routes and successfully transitioning candidate compounds from discovery into early development, as well as managing supply of Active Pharmaceutical Ingredients (APIs) at varying scales during this period.  Close collaboration with chemistry colleagues in Medicinal Chemistry and Process Chemistry, as well as a broad array of other discovery and preclinical research groups, will be expected.  As such, subject matter expertise in Medicinal or Process Chemistry is critical.

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
