FirstLook Lung is a blood-based test that helps identify lung cancer risk before or alongside LDCT, for USPSTF-eligible adults. From DELFI Diagnostics. Backed by Menlo.
About the role
The Senior Data Scientist will collaborate with a cross-functional team of laboratory scientists, clinicians, engineers, and other data scientists to develop statistical analysis methods supporting early cancer detection assays. This role spans assay development, analytical validation, and QC and control strategy, contributing to products advancing through verification, validation, and regulatory submission toward clinical use.
What they're looking for
- Master's degree in Applied Math, Statistics, Bioinformatics, Engineering, or a related quantitative field, PhD preferred
- Five or more years of practical experience in scientific or mathematical data analysis, with at least three years in Python (numpy, pandas, and similar)
- Strong foundations in probability theory and statistics, including hypothesis testing, confidence intervals, parameter estimation, and variance components
- Experience working in a regulated diagnostics environment (IVD, LDT, or similar), including designing and executing rigorous studies and analyses and documenting them appropriately
- Ability to connect assay chemistry to data behavior, applying this understanding to troubleshoot assay performance issues

About Us
DELFI Diagnostics, Inc. (DELFI Diagnostics) is developing next-generation, blood-based tests that are reliable, accessible and deliver a new way to help detect cancer. Employing advanced machine-learning methods to whole-genome sequencing data, the DELFI ("DNA EvaLuation of Fragments for early Interception") platform is built to address the highest-burden health challenges. DELFI Diagnostics prioritizes solutions that have the potential to save lives on a global scale, including for historically underserved populations. DELFI Diagnostics’ platform relies on fragmentomics – the discovery that cancer cells are more chaotic than normal cells and, when they die, leave behind tell-tale patterns and characteristics of cell-free DNA (cfDNA) fragments. FirstLook Lung, for individuals eligible for lung cancer screening, is DELFI Diagnostics’ first laboratory-developed screening test and can be part of routine blood work. FirstLook Lung uses millions of data points to reliably identify individuals who may have cancer detected through low-dose CT, including early stage disease with a negative predictive value of 99.8 percent. This test has not been cleared or approved by the FDA.
