GRAIL is seeking a Senior Scientist in the Assay Development team at our headquarters in Menlo Park to perform studies to support the development and integration of GRAIL's groundbreaking cancer screening products. You will be responsible for leading wet-lab research and development studies in support of product development goals, including the design, planning, execution, and analysis of complex experiments. The ideal candidate is a technically-rigorous team player with strong experience in automated NGS assay development, genomic data analysis, and outstanding communication skills. The ideal candidate has developed and successfully completed FDA approval for IVD product(s).

You Will:

• Be the technical lead on studies in support of the development, integration, and verification of automated NGS assays used in clinical laboratory products in a regulated environment
• Collaborate closely with other assay, automation, software, and operations team members to integrate and functionalize novel complex automated assays
• Drive development efforts to characterize and optimize assay performance, improve laboratory processes, and ensure production robustness
• Conduct troubleshooting investigations and related experimentation to address acute or systematic issues with implemented systems
• Collaborate closely with biostatistics and bioinformatics functions to develop robust study designs and comprehensive analyses
• Work with Quality and Regulatory team members to ensure studies fulfill necessary guidelines and regulations (CAP/CLIA/FDA)
• Develop experimental plans that support PMA study objectives
• Execute laboratory experiments in collaboration with more junior technical staff to generate high quality data by following best practices of assay and instrument operations
• Perform data analysis and document study outcomes and conclusions
• Summarize, present and document study outcomes to key stakeholders
• Support training of junior Research Associates

Your Background Should Include:

• PhD in Molecular Biology, Genetics, Cancer Genomics or similar relevant disciplines with 6+ years of postdoctoral or industry experience.
• Strong hands-on laboratory experience and in-depth knowledge of Illumina NGS workflows including nucleic acid extraction, library preparation, target enrichment, and sequencing.
• Hands-on experience with automated laboratory instrumentation such as liquid handlers or multi-functional workcells
• Experience with the development, optimization, and troubleshooting of NGS assay protocols a plus, in particular on automated systems
• Experience with standard nucleic acid analytical techniques (e.g, qPCR, Nanodrop, Fragment Analyzer, ddPCR)
• Experience with the development and implementation of clinical laboratory tests under CAP/CLIA or FDA/regulated environments
• Experience with design control and change control.
• Strong verbal and written communication skills, including proficiency in technical documentation such as study protocols and reports
• Experience with statistical programming or software (e.g, R, JMP)
• Experience with Design of Experiment (DOE) a plus
• Attention to detail, safety, good laboratory practice, and good documentation practice
• Willingness to collaborate cross-functionally in a fast-paced and dynamic environment
