FingerprintJS empowers developers to solve online fraud at the source.

    We are a 100% remote company with a strong open-source culture.

    Our flagship open source project is FingerprintJS (12.8K stars on GitHub).

    We work on turning radical new ideas in the fraud detection space into reality. Our products are developer-focused and our clients range from solo developers to publicly traded companies.

    Recently we raised $12M, backed by Nexus VP (previously invested in Postman, Hasura) and Uncorrelated Ventures (previously invested in Redis, Rollbar & Gradle).

    We’re looking for a senior full-stack developer to help us build a high performance, high accuracy online fraud prevention service. We need someone who has experience building React apps and server-side APIs.

    • How would you represent a mathematical vector? Please provide a basic implementation that supports core operations (cross product, dot product etc).

    Any applications that don't answer the question will be ignored due to the high volume of applications and lack of ability of candidates to fully read the job description :).
