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 Eva Luation 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. First Look Lung, for individuals eligible for lung cancer screening, is DELFI Diagnostics’ first laboratory-developed screening test and can be part of routine blood work. First Look 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.

In our passionate pursuit to radically improve health outcomes, we serve humanity when we:

We pioneer life-changing science by ensuring quality, transparency, and rigor at all times. We explore thoughtfully, experiment smartly, and deliver impact with conviction.

We embrace diverse backgrounds to innovate and achieve together. We are not just building a product - we aim to disrupt the path of cancer for all - no matter geography or socioeconomic class

We are a home for high-performing people. Through teamwork, we build collective intelligence. Each of us wins when those we serve and those who serve with us--win. We show up with empathy, humility, and integrity at every step of the journey.

We're hiring an experienced data scientist to analyze and model high-dimensional molecular data across emerging data modalities in support of our oncology-focused cancer detection platform. You'll work at the intersection of cancer biology and data science, owning projects end-to-end while partnering closely with assay development and experimental teams. This is a high-impact role for someone who thrives in ambiguity and is energized by hard problems in early cancer detection.

• Own end-to-end analysis of high-dimensional molecular work streams across multiple data modalities, from data processing through interpretation and communication of results
• Contribute to classifier design, development, and validation to detect cancer in prospective clinical studies
• Adapt external, state-of-the-art representation and foundation models for DELFI’s internal applications
• Collaborate closely with Assay, Software, and Clinical teams to evaluate and integrate emerging data types into analytical pipelines
• Support data science coverage across active studies, including assay research, characterization and validation
• Work effectively in a fast-moving environment where priorities shift and self-direction is expected

• Doctoral degree in Computational Biology, Bioinformatics, Data Science, or a related field with 2+ years of industry experience; or, Master's with 3+ years of industry experience; or, Bachelor’s with 5+ years of industry experience
• Hands-on experience with high-dimensional biological datasets across multiple biomarkers and molecular data types
• Background in cancer biology or oncology-focused research
• Demonstrated ability to own projects end-to-end with limited oversight
• Demonstrated ability to use experimental findings to drive decisions for future research or product directions
• Strong collaborator with wet lab and experimental teams
• Proficiency in Python; experience with cloud environments (AWS preferred)

• Experience with cfDNA, liquid biopsy, and NGS-based platforms
• Familiarity with ML modeling in a…
