Senior Full Stack Developer – Frontend Focus (UX/UI)

Build the Future of Spatial Biology Analysis

Katana Labs is a German TechBio startup, founded in 2023. We're building the AI-powered platform that's transforming how researchers analyze spatial biology data. Our cloud platform, Katana Edge, is already used by leading biotech and life science organizations to turn complex microscopy images into actionable insights – accelerating cancer research and drug discovery.

Katana Edge is redefining how scientists decode tissue biology in life sciences, biopharma R&D and precision medicine. By combining cloud-native infrastructure with powerful AI, Katana Edge turns terabytes of complex imaging and molecular data into intuitive, actionable insights - all within the browser. This enables R&D teams to uncover spatial biomarkers, understand tumor-immune interactions, and accelerate the development of precision therapies.

As a small, deeply experienced, and fast-paced team, we're at the intersection of cuttingedge AI, spatial data science, and cancer biology. Now, we are looking for a highly skilled and motivated senior full-stack engineer to join our company and advance Katana Edge for global scalability.
