Job Description

Blockchain is connecting the world to the future of finance. As the most trusted and fastest-growing global crypto company, it helps millions of people worldwide safely access cryptocurrency. Since its inception in 2011, Blockchain has earned the trust of over 90 million wallet holders and more than 40 million verified users, facilitating over $1 trillion in crypto transactions.

Our engineering team is building technologies that are revolutionizing the financial services industry by empowering millions across the globe. We are looking for a Android engineer to join our growing engineering team, to rapidly create, iterate and launch high-quality software that empowers users all over the world. Ultimately, you should be able to adapt easily to meet the needs of our fast growth and the rapidly evolving crypto ecosystem.

Our development team is tackling some of the most interesting problems in the crypto space while rapidly and securely scaling a distributed platform that touches millions of people a day. We want you to join us!

WHAT YOU WILL DO

  • Build & Ship: Contribute to our industry-leading Bitcoin and crypto wallet – View on App Store. You’ll write reliable, well-tested Kotlin code, collaborate with senior engineers on architecture decisions, and help guide junior teammates when needed. 
  • Learn & Grow: Deepen your expertise through code reviews, architecture discussions, and technical deep-dives. You’ll own medium-sized features end-to-end while continuing to sharpen your skills in mobile security and crypto.
  • Collaborate: Work closely with designers, product managers, and other engineers to translate user stories into delightful mobile features.
  • Own Features: Take full responsibility for feature development—planning, debugging, testing, and releasing to production—with an eye toward continuous improvement and scalability.
  • Stay Curious: Explore the latest tools (Kotlin Coroutines/Flow, Jetpack Compose, Tink, etc.), share insights with the team, and champion best practices.

WHAT YOU WILL NEED

Must-Haves

  • 2-5 years of professional Android development experience
  • Proficiency in Kotlin (and familiarity with Java)
  • Comfort with Android Studio, Jetpack Compose/Views, Gradle, and Git
  • Hands‑on experience shipping at least one consumer app to Google Play (internal testing tracks, closed/open testing, production release, Play Console management)
  • Solid grasp of asynchronous programming (Coroutines/Flow/RxJava) and common architectural patterns (MVVM/MVI)
  • Commitment to unit testing and automated CI/CD pipelines
  • A growth mindset—you actively seek feedback, iterate rapidly and push yourself to improve
  • Clear communication skills and enjoyment of working in diverse, distributed teams

Nice-to-Haves

  • Experience mentoring or pairing with junior engineers
  • Personal interest in crypto or fintech
  • Knowledge of advanced app-security or cryptography concepts
  • Familiarity with automated UI-testing frameworks (Maestro)
  • An app or project in Google Play or on GitHub you can demo
  • Exposure to performance profiling and memory-management tools

HOW WE WORK

  • Mentorship First: Regular 1-on-1s, peer design reviews, and open architecture forums help everyone level up.
  • Quality Matters: We test thoroughly, automate where it counts, and never compromise user trust.
  • Iterate Rapidly: Small, safe releases get real features into millions of hands—fast.
  • Global Mindset: Our team spans the globe; clear communication and async collaboration are core skills.
