Staff Data Engineer, Advanced Insights & Modeling

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 Advanced Insights and Modeling (AIM) team is a high-impact, business-savvy group of builders: machine learning engineers, data scientists, data engineers, and business strategists who combine technical skills with deep product and financial expertise. We hold high standards, move fast, and own our models end to end. AIM runs on curiosity, bold thinking, and collaboration, and we keep the culture decidedly non-corporate. Teams across Block come to us when they need insight, speed, and real business impact.

AIM sits within Block’s Foundational organization and is sponsored directly by the CFO, but our mandate runs well beyond Finance. We own most of the measurement and predictive modeling at Block: forecasting across Cash App, Square, and Afterpay, customer lifetime value, marketing incrementality and spend optimization, sales pipeline and prospect value, and actives and network-effect measurement. Finance, Marketing, Sales, Product, and Risk all plan against numbers we produce. We also own the data foundations those models run on, and corporate functions including Finance, Accounting, Treasury, SFS, and Procurement increasingly come to us when they want to rethink how their work gets done with AI.
