Fingerprint empowers developers to stop online fraud at the source.

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. We are a globally dispersed, 100% remote company with a strong open-source focus. Our flagship open-source project is FingerprintJS (20K stars on GitHub).

We have raised $77M and are backed by Craft Ventures (previously invested in Tesla, Facebook, Airbnb ), Nexus Venture Partners (previously invested in Postman, Apollo.io, MinIO, Druva) and Uncorrelated Ventures (previously invested in Redis, Rollbar & Gradle).

Fingerprint is the world's most accurate visitor identifier platform, offering a suite of advanced smart signals including bot detection (capable of identifying even stealth plugins from well-known automation tools), industry-leading VPN detection, and browser tampering detection powered by machine learning.

We are seeking a Senior R&D Engineer to join our team and help expand and mature our existing Smart Signals, as well as develop new ones from scratch. The ideal candidate will be an expert in TypeScript with a deep understanding of web technologies. Additionally, we require broad understanding of software engineering and be eager to learn new technologies and approaches to tackle open-ended, challenging problems.

• Knowledge of the HTTP protocol and web security practices.
• Broad knowledge of software engineering principles.
• Willingness to learn and work with various technologies and methods.

Compensation Range

$130,000 - $190,000 For cash compensation, we set standard ranges for all US based roles based on function, level and geographic location, benchmarked against similar stage growth companies. In order to be compliant with local legislation, as well as to provide greater transparency to candidates, we share salary ranges on all job postings regardless of desired hiring location.

Offers vary depending on, but not limited to, relevant experience, education, certifications/licenses, skills, training, and market conditions. 

Due to regulatory and security reasons, there’s a small number of countries where we cannot have Fingerprint teammates based. Additionally, because Fingerprint is an all-remote company and people can join our workforce from almost any country, we do not sponsor visas. Fingerprint teammates need to be authorized to work from their home location.

We are dedicated to creating an inclusive work environment for everyone. We embrace and celebrate the unique experiences, perspectives and cultural backgrounds that each employee brings to our workplace. Fingerprint strives to foster an environment where our employees feel respected, valued and empowered, and our team members are at the forefront in helping us promote and sustain an inclusive workplace. We highly encourage people from underrepresented groups in tech to apply.
