Staff Android Software Engineer, Cash App Consumer Platform

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 Team

The Cash App Consumer Platform is responsible for laying the foundation that every Cash App engineer builds on. We own the shared systems, abstractions, and tooling that power product development across the app. We sit at the product platform layer, building on top of core systems enabling feature development. Our customers are the engineers and teams building Cash App's product experiences, and we measure our success by their velocity and quality.

As AI fundamentally reshapes software engineering, Cash’s Consumer Platform is uniquely positioned to define what AI-native development looks like at Cash App and Block, both by building AI-powered capabilities into our platform and by establishing the practices that help hundreds of engineers leverage AI effectively every day.

The Job

As a Staff Android Engineer on Cash App Consumer Platform, you are a multiplier for the entire client engineering discipline. You think in systems. You spot problems before they have names. You create platforms and patterns that make the right thing easy and the wrong thing hard. You operate at an organizational scope. Your work shapes how hundreds of Builders build and how millions of customers experience Cash App.

You don't wait to be handed a problem - you identify what needs to exist, build the case for it, and lead the work to completion. You bring deep Android expertise and a genuine conviction that AI is a transformative force in how we build software, and you act accordingly. This role reports to the Cash App Product Platform Lead.
