Job description

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 (27K 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’re looking for a Senior Android Engineer with a strong background in Native Android development to join our Mobile team. This is a high-impact role at the intersection of mobile engineering and security, where you’ll help shape the future of mobile device intelligence and fraud prevention.

You’ll be a key contributor to our Android SDKs-building cutting-edge detection signals, optimizing performance, and delivering an exceptional developer experience. You’ll also collaborate closely with product managers, backend engineers, and data analysts to drive innovation through new methodologies and data-informed decisions.

What You’ll Do:

Lead the development and evolution of our Android products:

• Fingerprint Android PRO SDK – Design and implement detection signals; improve performance, stability, and reliability.
• Fingerprint Android OSS SDK & Showcase App – Maintain and advance our open-source offerings.
• Fingerprint Device Intelligence Demo App – Build new features and implement UI screens from Figma designs using Jetpack Compose.
• Provide technical expertise and insights to product and analytics teams—for example, assessing Android market data (e.g., the share of Vivo devices using MTK SoCs) using internal tools and our data warehouse.
• Research and prototype new methodologies that enhance our fraud prevention capabilities, efficiency, and technical edge.
• Conduct post-deployment analysis on collected data and collaborate on improving server-side logic and detection systems.
• Work cross-functionally with backend engineers, PMs, and security researchers to deliver impactful features end-to-end.

What We’re Looking For:

• 5+ years of hands-on Android development experience in a senior-level capacity.
• Strong foundation in Information Security , with prior experience as an Android engineer in a security-focused organization or on a security-centric product.
• Demonstrated ability to build native Android applications and SDKs from the ground up.
• Deep understanding of Android internals and system behavior.
• Proficiency in Kotlin and the Android SDK ; hands-on experience with Jetpack Compose for UI development.
• Experience with C++
• Experience building tools for other developers is a strong plus.
• Data-savvy mindset with a comfort level working with product and data teams.
• Excellent written and verbal communication skills; thrive in a remote-first, async team environment.

Nice to Have:

• Experience with GitHub Actions
• Familiarity with obfuscation techniques or related low-level Android security concepts.
• Open-source contributions—share your GitHub profile if applicable.
• Interest in expanding into backend development, such as writing backend detection logic.
• Engagement in the InfoSec community through conference speaking, writing, or active participation.

For US-based employees , the cash compensation range for this role is $178,000 - $205,000. We set standard ranges for all US roles based on function, level, and geographic location, benchmarked against similar stage growth companies. To comply with local legislation and provide greater transparency, we share salary ranges on all job postings. However, these ranges are specific to the hiring location and may differ within or outside the US.

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.
