The Clinical Laboratory Specialist V is responsible for advanced post-analytical review activities supporting high-throughput clinical genomics testing within a regulated CLIA/CAP laboratory environment. This role focuses on comprehensive review of assay and bioinformatics-generated data following completion of laboratory and computational workflows to ensure accuracy, integrity, and quality of patient results prior to report release.

The individual performs detailed technical assessments of sequencing and assay performance metrics, evaluates data quality trends, investigates discrepancies, and supports timely and compliant report release activities. The role requires strong molecular biology and next-generation sequencing (NGS) knowledge, excellent analytical skills, and the ability to independently assess complex laboratory data within established quality and regulatory standards.

This position operates as an individual contributor within the clinical laboratory and plays a critical role in ensuring high-confidence patient reporting through rigorous data review and quality oversight.

This position works on-site full-time at our office located in Durham, NC

• Perform comprehensive post-analytical review of clinical laboratory data generated from high-throughput genomics workflows, including assessment of sequencing quality metrics, assay performance indicators, and bioinformatics pipeline outputs prior to report release.
• Evaluate laboratory and computational quality control metrics to ensure accuracy, completeness, consistency, and integrity of patient results in accordance with established laboratory procedures and regulatory requirements.
• Review batch-level and sample-level data following bioinformatics processing to identify technical issues, quality concerns, assay anomalies, or unexpected performance trends requiring further investigation or escalation.
• Support clinical report release activities by verifying data quality, confirming review completion, and ensuring all required documentation and quality checks are satisfied before final authorization.
• Perform technical assessment of molecular assay performance across multiple workflow stages, including specimen quality, library preparation, sequencing performance, contamination monitoring, and downstream analytical outputs.
• Investigate routine and non-routine data discrepancies by applying molecular biology knowledge, assay expertise, and analytical reasoning to determine potential root causes and appropriate resolution pathways.
• Accurately document review findings, quality observations, deviations, and follow-up actions within laboratory information management systems (LIMS), quality systems, and other regulated documentation platforms.
• Collaborate with laboratory operations, bioinformatics, quality, and reporting teams to resolve data quality issues, support turnaround time objectives, and maintain operational continuity within high-volume testing environments.
• Participate in quality monitoring activities, including trend analysis, quality metric tracking, and identification of recurring workflow or assay performance issues that may impact result quality or laboratory efficiency.
• Contribute to continuous improvement initiatives by identifying opportunities to optimize…
