About the Job

Requirements

  • A PhD in Biochemistry, Bioengineering, Biology, or a related field with 0–3 years of experience in the pharmaceutical or biotechnology industry; or a BS with 10+ years or an MS with 8+ years of extensive cell-based bioassay experience in the pharmaceutical or biotechnology industry.
  • Strong hands-on experience developing cell-based bioassays, plate-based potency assays such as ELISA, AlphaLISA, or Lumit, and large mammalian cell banks.
  • Experience with potency assay statistical software such as Softmax Pro, PLA, or JMP.
  • Experience maintaining and qualifying equipment used for potency and cell-based methods, including incubators, biosafety cabinets, plate readers, and controlled-rate freezers.
  • Strong understanding of cell-based mechanisms of action and the relationship between potency and other critical quality attributes.
  • Ability to interpret data and communicate and present results to peers and management.
  • Proficiency in Microsoft Office, Word, and Excel.
  • Demonstrated ability to build and maintain collaborative relationships across functional areas and with management.
  • Detail-oriented, proactive, and self-motivated, with strong analytical, problem-solving, and multitasking capabilities.
  • Ability to perform intermittent physical activities including bending, reaching, pushing, pulling, or lifting up to 40 pounds; the work may involve prolonged sitting and working with or near hazardous materials.

Responsibilities

  • Develop, test, transfer, qualify, and validate bioassay methods in development and good manufacturing practice quality control environments.
  • Troubleshoot method and equipment challenges, including optimizing cell culture of challenging cell lines and introducing the methods into quality control environments.
  • Author standard test methods, technical reports summarizing analytical data, and qualification and validation reports.
  • Perform in-process, release, characterization, comparability, and stability testing of clinical and commercial products.
  • Participate in cross-functional teams as a representative of the Bioassay group.
  • Troubleshoot bioassay-related problems from third-party vendors, including contract research organizations and contract development and manufacturing organizations.
  • As applicable, perform investigations, including deviations, out-of-specification, out-of-trend, and out-of-control results, test method failures, and method-related root cause analyses.
  • Ensure laboratory equipment is calibrated and maintained in proper working order to support compliance with good laboratory and/or good manufacturing practice environments.
  • Contribute to drafting regulatory submissions, including IND/IMPD and BLA/MAA submissions and health authority responses.
  • Ensure test method development and execution comply with applicable regulatory requirements, internal policies, scientific standards, and project timelines.
  • Travel up to 10% of the time.

Desired Qualifications

  • Experience with orthogonal cell-based bioassay techniques, including IncuCyte, flow cytometry, and liquid handler implementation.
  • Experience supporting good manufacturing practice release and stability testing for clinical and/or commercial biologic products.
  • Experience with electronic laboratory notebooks, laboratory information management systems, and data analysis platforms.
  • Knowledge of current good manufacturing practices, International Council for Harmonisation guidelines, regulatory expectations, data integrity requirements, and quality management systems.
  • Experience in qualification, transfer, and validation of bioassays, internally and in managing third-party contract research organizations and contract development and manufacturing organizations.

About the Company

Omeros

Biopharmaceuticals discovering, developing, commercialising therapeutics

Omeros develops medicines that target the body's complement system, using both small-molecule drugs and biologics. Its lead drug narsoplimab (Yartemlea) is a monoclonal antibody that blocks MASP-2, and it was approved by the FDA in December 2025 for transplant-associated thrombotic microangiopathy (TA-TMA). The company also advances OMS906, a complement factor D inhibitor studied for diseases like paroxysmal nocturnal hemoglobinuria. Its goal is to provide therapies for complement-driven diseases and broaden its portfolio, including ongoing European regulatory reviews.
