Key Responsibilities

Kit QC & Functional Testing (Primary)
  • Own and execute functional testing plans for commercial kit lots including incoming components, in-process materials, and final kit performance testing.
  • Run routine QC assays, including as applicable:
  • qPCR/RT-qPCR for recovery, inhibition checks, and linearity.
  • TapeStation/Bioanalyzer for size profiles, integrity, and yield QC.
  • Fluorometric quantification including Qubit, PicoGreen, and RiboGreen.
  • Extraction performance checks including yield, reproducibility, carryover, and contamination controls.
  • Prepare and process biological samples including plasma, urine, whole blood, and contrived controls according to SOPs.
  • Track lot performance, generate QC summaries and CoA-support data, and flag out-of-specification trends.
  • Investigate deviations and failures, perform root-cause analysis, and recommend corrective actions with R&D, Manufacturing, and Quality.
Cross-Functional Support
  • Partner with Manufacturing to ensure smooth tech transfer and readiness for scale, including materials, build records, and test readiness.
  • Coordinate with Quality on documentation, change-control support, and release criteria.
  • Support troubleshooting of customer-reported issues by recreating conditions and documenting findings.
Routine R&D Work (Secondary)
  • Assist with protocol optimization, method verification, and robustness studies.
  • Support automation workflows as needed including Hamilton or internal platforms, with run setup, execution, and data review.
  • Maintain lab organization, instrument upkeep, reagent preparation, and inventory management.
  • Maintain high-quality documentation including lab notebooks, raw data files, SOP updates, and summary reports.

Qualifications

Required
  • B.S. in Molecular Biology, Biochemistry, Chemistry, Biomedical Engineering, or a related field. M.S. preferred.
  • 2+ years of hands-on experience in a molecular biology lab. Industry experience preferred.
  • Demonstrated experience with DNA/RNA extraction and qPCR/RT-qPCR.
  • Strong attention to detail and comfort working in a structured, repeatable testing environment.
  • Ability to produce clear documentation and communicate results to cross-functional teams.
Preferred
  • Experience with cfDNA/cfRNA/cfTNA workflows, low-input samples, or liquid biopsy.
  • Experience with TapeStation/Bioanalyzer, NGS library QC, or inhibition and contamination-control strategies.
  • Familiarity with GxP/ISO concepts, change control, deviations, and data-integrity principles.
  • Experience supporting automation platforms including Hamilton.
  • Comfortable analyzing data in Excel. Basic statistics, graphing, or scripting experience is a plus.

Skills & Attributes

  • Highly organized, reliable, and execution-focused.
  • Strong troubleshooting mindset and ability to identify patterns and trends across lots.
  • Collaborative and comfortable working with R&D, Manufacturing, and Quality.
  • Able to manage multiple tests and priorities while maintaining accuracy.

Working Conditions

  • Lab-based role handling human-derived specimens with appropriate training and PPE.
  • May require occasional schedule flexibility to support builds, releases, or time-sensitive studies.

Success Metrics First 3–6 Months

  • Independently executes the functional testing plan for kit lots with minimal supervision.
  • Produces consistent, audit-ready QC documentation and summaries.
  • Helps reduce retests and failures through early detection of issues and clear root-cause investigations.
  • Contributes meaningfully to routine R&D studies and continuous-improvement efforts.
