Software Engineer Intern - Summer 2026

About Novaflow Novaflow is the AI data analyst for biology labs. Analytics is the bottleneck for scientific discovery. Biologists have to outsource analysis to expensive bioinformaticians or core services and wait weeks or months for results. We're solving this by putting analysis directly back into the hands of researchers, allowing them to go from raw data to publication‑ready insights and visualizations in days instead of months. We're well‑funded, growing extremely fast, and backed by leading investors including YCombinator and BioRender. About The Role We're hiring a Software Engineer Intern to help build the backend infrastructure and services that power our platform. You'll work on APIs, cloud infrastructure, databases, and data pipelines that move real genomics data through the system. The code you write will ship to production and be used by scientists. This is not a sit‑in‑the‑corner internship. We're a small team and you'll work directly with the founders on real problems from day one. We're looking for someone with high agency who takes initiative and doesn't wait to be told what to do. Biology background is not required. This role can be remote or in‑person at our SanFrancisco office. There is potential to convert to a full‑time position based on performance.
