mobile software engineer, android jobs



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.


We’re looking for an Android developer to help us build a high performance, high accuracy online fraud prevention service. We need someone who has experience building developer-focused SDKs and tools to integrate into other applications.

This is not a job to build yet another app, it’s a research-heavy, low-level position for an inquisitive mind.

What we’re looking for 👀 :

  • Good understanding of networking protocols and communication patterns.
  • Experience building developer-focused tools or libraries for the Android platform.
  • Excellent understanding of Android security/privacy mechanisms.
  • Proven experience of SDKs/libraries architecture and implementation.
  • Good English

Don’t be afraid to apply even if you’re missing a few bullet points in there!

Ideally we would love to have someone who also has:

  • Historical record of open-source contributions
  • Security / Cryptography background

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 question to work@fingerprintjs.com:

  • How would you identify an Android app reinstall without using built-in UUID?

We highly encourage people from underrepresented groups in tech to apply.

We encourage people without degrees to apply: we believe that what you’ve worked on and achieved is way more important than on-paper qualifications.
