Job description

We are a fast-growing and dynamic organization seeking a Quality Control Associate / Sr Quality Control Associate to join our CMC team.

This position will be primarily responsible for QC data review of data packets and reports from external vendors. The role has hands-on experience with performing one or more physicochemical methods such as chromatographic methods (SEC, RP-HPLC, peptide map, CEX), electrophoretic methods (CE-SDS, SDS-PAGE, and icIEF), and compendial assays (pH, osmolality, endotoxin, sterility) and will be familiar with method troubleshooting.

This role will also assist the broader QC team with GMP investigations and oversight, and additionally, will assist with non-GMP in-lab support for deviations and critical reagent management.

Omeros’ lead complement inhibitor YARTEMLEA ® (narsoplimab-wuug), which targets the lectin pathway’s effector enzyme MASP-2, is FDA-approved and commercially available in the U.S. for the treatment of hematopoietic stem cell transplant-associated thrombotic microangiopathy (TA-TMA) in adult and pediatric patients aged two years and older.

OMS1029, Omeros’ long-acting MASP-2 inhibitor, has successfully completed Phase 1 clinical trials. Under an asset purchase and licensing agreement, Novo Nordisk acquired global rights to zaltenibart (formerly OMS906), an inhibitor of MASP-3, the alternative pathway’s key activator, which is in clinical development for PNH and other alternative pathway indications, along with associated intellectual property and related assets.

Omeros’ pipeline also includes OMS527, a phosphodiesterase 7 inhibitor in clinical development for cocaine use disorder, which is fully funded by the National Institute on Drug Abuse, and a growing portfolio of novel recombinant antibodies targeting multidrug-resistant organisms and novel molecular and cellular therapeutic programs for oncology.
