If you're driven by purpose, energized by innovation, and ready to help shape the future of precision medicine at scale, this is where you belong.

We seek a Process Engineering Associate II whose interests span molecular diagnostics, process optimization, and quantitative problem solving. In this role you will (1) drive process improvement and development to enhance clinical assay performance, (2) support technology transfer from R&D into our high‑throughput CLIA lab, and (3) troubleshoot and identify root causes of recurring errors to enable long‑term corrective actions. You will also play a key role in standing up our newly built lab in Austin, TX.

You will leverage and deepen your expertise across molecular techniques, laboratory automation, and data analysis while contributing directly to category‑defining NIPT assays that transform patient lives one molecule at a time. This onsite position starts at our Union City, CA laboratory and will relocate to Austin, TX in summer 2027. The Process Engineering Associate II reports to the Senior Development Scientist.

Austin Expansion Update: We are building a brand‑new state‑of‑the‑art laboratory in Austin, Texas
, expected to launch in late 2027 / early 2028
, and we are looking for talented laboratory professionals who want to be part of this journey from the very beginning. Candidates hired into this role will initially relocate to the Bay Area (Union City, CA) to train and work alongside our experienced laboratory teams. During this time (up to ~18 months), you will gain deep hands‑on experience with Billion To One ’s cutting‑edge molecular diagnostic workflows, quality systems, and laboratory operations before transitioning to our new Austin facility once it opens.
