Senior Research Associate, Formulation Development 



This position will be responsible for formulation development of monoclonal antibodies to support preclinical, clinical, and commercial phase of multiple programs. The position is both a hands-on laboratory-based role and requires management of outsourced projects.

Formulation development activities include excipient screening and optimization, stability testing and characterization of routes of degradation of proteins in liquid and lyophilized formulations under various stresses. Laboratory activities include buffer and protein solution preparation, pipetting and aseptic operations in a biosafety cabinet.

Activities in support of Drug Product manufacturing may be performed, which include mixing studies, process robustness and tech transfer.


About Omeros Corporation 


Omeros is an innovative biopharmaceutical company committed to discovering, developing and commercializing small-molecule and protein therapeutics for large-market and orphan indications targeting inflammation, immunologic diseases (e.g., complement-mediated diseases) and cancers. Omeros’ lead MASP-2 inhibitor narsoplimab targets the lectin pathway of complement and is the subject of a biologics license application pending before FDA for the treatment of hematopoietic stem cell transplant-associated thrombotic microangiopathy. Narsoplimab is also in multiple late-stage clinical development programs focused on other complement-mediated disorders, including IgA nephropathy, atypical hemolytic uremic syndrome and COVID-19. OMS906, Omeros’ inhibitor of MASP-3, the key activator of the alternative pathway of complement, is in a Phase 1 clinical trial. For more information about Omeros and its programs, visit
