  • Work with RnD to identify CPPs, process tolerances, and failure modes during late stage product development.
  • Work with Bioinformatics and data science to translate assay CQAs into impactful and actionable process monitoring tools.
  • Develop new data and information handling tools to aid in efficient sample processing within the clinical laboratory.
  • Apply six sigma, Design-for-quality, and 5S frameworks to existing or new processes to improve both capability, scalability, and quality of molecular diagnostic assays.
  • Support high throughput CLIA lab through troubleshooting instrumentation and re-qualifying instrumentation back into clinical use.
  • Identify root causes for process and instrument errors and develop short term and long term solutions.
  • Develop effective training plans for clinical personnel on modified/improved workflows.
  • Generate proper documentation for all troubleshooting and qualification.

  • Start-up experience
  • Knowledge of medical genetics
  • Experience in a cell-free DNA setting
  • Experience with 6-sigma, Lean, JIT, TPS
  • Experience with CLIA/CAP, 510K, PMA, and other regulatory requirements

Benefits And Perks:

  • Working alongside brilliant, kind, passionate and dedicated colleagues, in an empowering environment, toward a global vision, striving for a future in which transformative molecular diagnostics can help millions of patients
  • Open, transparent culture that includes weekly Town Hall meetings
  • The ability to indirectly or directly change the lives of hundreds of thousands patients
  • Multiple medical benefit options; employee premiums paid 100% of select plans, dependents covered up to 80%
