Position Summary

We are seeking a Principal Research Scientist to lead our Molecular Pharmacology team and in vitro pharmacology strategy across Small Molecule, Large Molecule, and Parasitology discovery.

Show full description

This role requires strong small-molecule drug discovery experience, deep cell-based and biochemical assay expertise, direct people leadership, and the ability to translate pharmacology data into lead optimization and candidate-selection decisions.

What You’ll Do (Your Impact)

Lead and develop a team of scientists.
Own in vitro pharmacology and assay strategy across discovery programs.
Design and optimize cell-based and biochemical assays for potency, MOA, target engagement, and cellular response.
Partner with medicinal chemistry and discovery teams to support SAR, lead optimization, and candidate progression.
Provide scientific leadership across multiple programs and build new assay capabilities where needed.
Ensure high-quality pharmacology data supports go/no-go and candidate-selection decisions.

What You Need to Succeed (minimum qualifications):

Ph.D. in a related scientific discipline with 12+ years of relevant industry experience, or M.S. with 15+ years.
Strong experience in molecular/in vitro pharmacology and small-molecule drug discovery.
Demonstrated ownership of assay strategy and development, not just assay execution.
Experience supporting compound characterization, lead optimization, and progression decisions.
Direct people-management experience, including coaching and developing scientists.
Strong cross-functional scientific leadership within drug discovery.

What will give you a competitive edge (preferred qualifications):

Extensive medicinal chemistry partnership and SAR experience.
Experience with biologics or other large-molecule modalities.
Parasitology or parasite-host biology experience.
Experience with automation, HTS, or building new assay platforms.

Additional Information:

This role is based in Indianapolis and will work closely with cross-functional discovery teams across Elanco R&D.
