Senior Applied Data Scientist
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 app, bringing a better way to send, spend, invest, borrow and save to our millions of monthly active users. With a mission to redefine the world's relationship with money by making it more relatable, available and accessible, at Cash App you'll have the opportunity to make a real-world impact with your career. Today, Cash App has thousands of employees around the world with a culture geared toward creativity, collaboration and impact. We've been a distributed team since day one, and continue to value working across time zones and continents both remotely and in our Cash App offices.
Our offices are great, but many of our roles can be done remotely from the countries where Block operates. We tailor our experience to champion our employees' creativity and productivity wherever they are.

The Cash App Quantitative Finance Team is an intellectually diverse team of machine learning modelers, statisticians, economists, data scientists, former strategy consultants, and data engineers focused on applying graph analytics, statistics, econometrics, and machine learning algorithms to solve business problems for executives within Cash App and the broader Block organization.
The team has answered some of the most complex questions around how our network is formed and evolves, why our customers churn or re-engage with the platform, and why they choose to move money into or out of the platform. The outputs of our team are used to drive high level company strategy across product development, marketing, and financial strategy. We partner across the broader Block ecosystem and work directly with Foundational Engineering, Data Engineering, marketing, customer insights, and finance. In 2024 we are going to reimagine strategy and automation within Cash, serving as a guidepost for the overall Block organization.

- PhD plus 2 years (or Master plus 4 years) industry working experience in developing machine learning / statistical models to solve real world problems (e.g. classification, NLP, regression, panel models, time series, etc.).
- Outstanding written and oral communication skills to present and explain the functioning of the models to exercise influence amongst Cash and Block Executives
- Experience using business intuition on what drives adoption of certain products to develop predictive models.
- A strong track record of performing machine learning model development using Python (numpy, pandas, statsmodels, scikit-learn, etc.) and SQL/NoSQL interaction patterns.
- Familiarity with Linux/OS X command line, version control software (git), and general software development principles with a machine learning software development life-cycle orientation.
