Founding Backend Engineer

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 Y Combinator and BioRender. About the Role We're hiring a Founding Backend Engineer to build the infrastructure and services that make the whole platform work. APIs, cloud infrastructure, databases, data pipelines for moving large genomics datasets through the system. You'll make the architecture decisions that determine how this thing scales. This is a high-agency, high-ownership role. You'll work directly with the founders on system design and have a major say in how we build our engineering team and processes.
