Our mission is to detect cancer early, when it can be cured. We are working to change the trajectory of cancer mortality and bring stakeholders together to adopt innovative, safe, and effective technologies that can transform cancer care.
We are a healthcare company, pioneering new technologies to advance early cancer detection. We have built a multi-disciplinary organization of scientists, engineers, and physicians and we are using the power of next-generation sequencing (NGS), population-scale clinical studies, and state-of-the-art computer science and data science to overcome one of medicine’s greatest challenges.
GRAIL is headquartered in the bay area of California, with locations in Washington, D.C., North Carolina, and the United Kingdom. It is supported by leading global investors and pharmaceutical, technology, and healthcare companies.
The Data Engineer will partner with scientists and statisticians to support efficient and accurate capture, transfer, and aggregation of sample information and analysis results through GRAIL’s analysis systems. As such, the Data Engineer will become proficient in GRAIL’s system architecture, including primarily GRAIL’s LIMS for laboratory data; Electronic Data Capture (EDC) for clinical study data; the Bioinformatics Pipeline for sequence analysis and cancer classification data; and TidyData, the system that aggregates, packages, and serves datasets created from LIMS, EDC, and Pipeline outputs.
The Data Engineer will also collaborate with software engineers and scientists to develop requirements and produce analysis-ready datasets for clinical research and product development. The Data Engineer will develop code and procedures to support dataset generation, perform QC, and troubleshoot issues that arise during dataset generation. The Data Engineer will also collect requirements, develop prototypes, and collaborate on production implementations of new reporting, data visualization, and statistical analysis features as needed.
The Data Engineer will learn analysis requirements by reading laboratory protocols, Statistical Analysis Plans, and other analysis planning documents and meeting with scientists, biostatisticians, and other stakeholders. They will demonstrate a consistent commitment to delivering on team goals with a sense of shared urgency.
