FingerprintJS is a fully remote company with a strong open-source culture. We work on turning radical new ideas in the fraud detection space into reality. Our products are developer-focused and our clients range from freelancers to publicly traded companies.

Our team is small, ambitious and globally distributed (from Argentina to Russia). We’re both very technical and very friendly.

  • Front-end: TypeScript, React, Storybook.
  • AWS (Lambda, Elastic Beanstalk, RDS, DynamoDB).
  • Netlify.
  • PostgreSQL.
  • Docker.

What we offer:


  • Small team, lean hierarchy and no politics.
  • Budget for learning. We want you to grow with us, so we offer a $600 yearly budget that you can spend to learn new stuff (books, conferences, subscriptions, etc.).
  • Freedom to grow and experiment. Work on open-source projects and try new things and ideas.
  • Ability to influence the product development and quickly grow within the company.
  • Stock options.

To apply, send your CV with your GitHub profile and an answer to the below questions to work@fingerprintjs.com:
