  • Drive operational improvements, including 5S, laboratory automation, and process optimization, to increase the efficiency and robustness of testing workflows
  • Help uphold quality and compliance across CMI through sound documentation practices, data integrity, and audit-readiness
  • Prepare reagents, maintain inventory, and manage sample workflows efficiently
  • Analyze and interpret assay results and present findings to team members and leadership
  • Collaborate within the CMI group and cross-functionally to support vaccine development programs

Nice-to-Have

  • Experience with flow cytometry and understanding of its scientific principles
  • Knowledge of immunology and cellular immune responses
  • Familiarity with ELISPOT, ADCC or other biofunctional assays
  • Understanding of relevant statistics and data analysis
  • Experience with laboratory automation and high-throughput workflows
  • Experience with continuous improvement or Lean methodologies (e.g., 5S)
  • Familiarity with LIMS or other electronic laboratory systems
