FOSSA is hiring an Applied AI Software Engineer for a full-time onsite role in Toronto, joining a fast moving distributed R&D team building the next generation of the open source software supply chain platform using static analysis, deterministic algorithms and LLMs. You’ll own high impact features from concept to production, primarily in TypeScript with exposure to Rust, Haskell or Go, and contribute to multi language analysis for customers. The ideal candidate has 6+ years as a backend or fullstack engineer, experience shipping SaaS at high velocity, strong SQL and hands on with LLM APIs. To apply, highlight greenfield wins, prototypes that reached production, collaboration with R&D and product, and a metrics driven impact story showing growth mindset and comfort with distributed work.

If you’re like us, you agree that open source software is a wonderful and unique gift that the community of software developers across the world have given to each other. At FOSSA, we want to proliferate its usage with our software supply chain management platform that helps our customers know what licenses, vulnerabilities, and dependencies go into their software as they utilize open source software packages. And we won’t rest until all companies, big and small, love and feel as comfortable with using open source as we are.
