Build the Future of Software

FOSSA is the company defining how modern businesses
think about using open source

FOSSA is a fast growing Series B startup that’s solving a real and deeply technical problem in software engineering. Here you’re encouraged to take significant ownership in projects that create real impact. Our product helps teams track, automate license scanning and compliance of the open source used in their code. 

We recently expanded our product offering and launched a security product that helps companies with security vulnerabilities. Over 7,000 open source projects (Kubernetes, Webpack, Terraform, ESLint) and companies (Uber, Ford, Zendesk, Motorola) rely on FOSSA’s tools to ship software. By hiring people who are passionate about open source and fostering an environment of respect, acceptance and growth, we will continue to make our product the best in open source.
