Join to apply for the Lead Engineer - Research role at Fingerprint

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).
We have noticed a rise in recruiting impersonations across the industry, where scammers attempt to access candidates' personal and financial information through fake interviews and offers. All Fingerprint recruiting email communications will always come from the @fingerprint.com domain. Any outreach claiming to be from Fingerprint via other sources should be ignored.
We're looking for a Web Security Researcher to drive innovation in bot detection and web security. This role is ideal for a security-focused engineer or researcher with strong reverse engineering skills, a passion for anomaly detection, and a deep understanding of how the web works under the hood.
You'll lead the full research lifecycle from concept through implementation, creating tools and techniques to detect sophisticated bots before they ever reach production. You'll work alongside a world-class team that values autonomy, speed, and deep technical expertise.
What You'll Do

• Research and prototype advanced methods to detect and prevent sophisticated bots
• Reverse-engineer web automation tools and evasive techniques
• Build internal tools to test hypotheses and validate detection models
• Own the entire R&D cycle: from ideation to secure, production-ready implementation
  

What You Bring

• Proven ability to design and conduct complex security research projects
• Deep understanding of web browsers, web automation, and client-side evasion techniques
• Hands-on experience with JavaScript/TypeScript
• Strong reverse engineering skills
• Solid grasp of internet security and privacy mechanisms
• Ability to thrive in ambiguity and drive projects independently
• Excellent written and verbal communication in English
  

Bonus Points For

• Experience developing or bypassing bot detection systems
• Familiarity with bot mitigation strategies at scale
• Contributions to open-source security or reverse engineering tools
  

Compensation:
150 - 205k 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. Final offer amounts are determined by multiple factors including geographic location as well as candidate experience and expertise, and may vary from the amounts listed above.

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.
