Job description

It all started with an idea at Block in 2013. Initially built to take the pain out of peer-to-peer payments, Cash App has gone from a simple product with a single purpose to a dynamic ecosystem, developing unique financial products, including Afterpay / Clearpay, to provide a better way to send, spend, invest, borrow and save to our 50+ million monthly active customers. We want to redefine the world’s relationship with money to make it more relatable, instantly available, and universally accessible.

Today, Cash App has thousands of employees working globally across office and remote locations, with a culture geared toward innovation, collaboration and impact. We’ve been a distributed team since day one, and many of our roles can be done remotely from the countries where Cash App operates. No matter the location, we tailor our experience to ensure our employees are creative, productive, and happy.

The Role

At Block, we’re pioneering the future of Bitcoin by making it everyday money. The Bitcoin team works across our ecosystem (Cash App, Square, and more) to build innovative experiences that are helping millions of people access and use Bitcoin in their daily lives. We’ve been at the forefront of Bitcoin adoption since 2018, continuously pushing the boundaries of what’s possible with features like Bitcoin Payments on Square and Paid in Bitcoin on Cash App.

We’re looking for an Android Engineer to join our mission of economic empowerment through Bitcoin.

  • Help evolve our mobile architecture and development practices.
  • Collaborate with cross‑functional teams (mobile, backend, product, design) to deliver remarkable solutions.
  • Participate in technical design discussions and code reviews.
  • Have a meaningful impact on the future of Bitcoin.

You Have

  • 2+ years of experience in Android and Kotlin development
  • Track record of shipping user‑facing features in production apps
  • Experience with modern Android frameworks and libraries (Jetpack, Coroutines, etc.)
  • Understanding of mobile architecture patterns and best practices
  • Growth mindset and eagerness to learn new technologies
  • A commitment to continuous improvement (yourself, your teammates, your software)
  • Experience leveraging AI‑assisted development tools in your workflow
  • Technologies We Use and Teach

  • Kotlin, including multi‑platform
  • Unit tests, snapshot tests
  • AI‑powered developer tools like Goose, Cursor, and Claude Code to accelerate development and innovation
