Description

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.
In our passionate pursuit to radically improve health outcomes, we serve humanity when we:
Lead with Science, Anchor in Pragmatism: We pioneer life-changing science by ensuring quality, transparency, and rigor at all times. We explore thoughtfully, experiment smartly, and deliver impact with conviction.
Build With & For All: 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
Put We over I: 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.

Responsibilities


    • Design, develop, optimize assay, reagent, and quality control parameters to set tolerance limits and meet performance requirements for complex multiomic assays.

    • Develop robust processes for reagent manufacturing, reagent QC, and transfer to contract reagent manufacturers.
    • Perform rigorous design of experiment, data analysis, and act as subject matter expert by collaborating with assay biostatisticians, bioinformaticians, engineers, and scientists to determine key assay performance characteristics.
    • Document product development requirements and author study protocols and reports to ensure traceability and compliance with industry standards
    • Be accountable for development activities and advance the assay through design control processes to meet product requirements and project milestones by contributing to plans, risk assessment, and verification activities.
