  • Maintain laboratory instruments and ensure proper calibration and performance, supporting compliance with quality and safety standards.
  • Collaborate with cross-functional teams (e.g., protein production, process development) to support project timelines and deliverables.
  • Contribute to continuous improvement initiatives, including method refinement, workflow efficiency, and data quality enhancement.

Qualifications:

  • BS or MS in Biochemistry, Analytical Chemistry, Biotechnology, or a related field with 2+ years of relevant experience in protein analytical characterization or QC.
