Director, Analytical Development

At Keros, our mission is to deliver significant clinical benefit to a wide range of patients with disorders that are linked to dysfunctional signaling of the transforming growth factor-beta (TGF-ß) family of proteins. With a focus on developing differentiated product candidates that are designed to alter TGF-β signaling, we aim to target the pathways critical for the growth, repair and maintenance of blood cells and a number of tissues, including bone, skeletal muscle, adipose and heart tissue.

We believe our product candidates have the potential to unlock the full therapeutic benefits of modulating the TGF-β superfamily and provide disease-modifying benefit to patients.

Keros Therapeutics is seeking an expert in Analytical Science and Protein Characterization to join our team as Director of Analytical Development. The incumbent will lead the analytical strategy, method development, and characterization for our novel protein pipeline. The ideal candidate will have a deep understanding of protein characterization hands‑on experience in the laboratory, excellent organizational skills and attention to detail, a demonstrated ability for self‑motivated and independent project execution, and a strong desire to learn.

This position requires deep expertise in modern analytical chemistry and a strong ability to translate complex data into actionable scientific decisions. The ideal candidate will combine technical depth with proven leadership experience, sound scientific judgment, and the ability to build productive partnerships across internal teams and external collaborators.
