Senior Machine Learning Engineer - Identity

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

As part of the Machine Learning Engineering Identity team, you will play a critical part in utilizing machine learning methods and systems to reduce the prevalence of inauthentic identities within Cash's ecosystem. Our primary responsibility is fortifying our first line of defense against bad actors attempting to bypass our Identity Verification (IDV) controls, while also enhancing our confidence in the authenticity for both existing and new customers. By leveraging machine learning, we aim to ensure that everyone has equal access to the financial services they require, irrespective of their background or financial history.

Specifically this role focuses on using machine learning to develop risk-based experiences that increases access for good customers, ensuring that customers are using the type of account that helps them grow their network, grow their personal network / finances or grow their business, while providing guardrails against risky customers.

Our team is continuing to grow and we're looking for Engineers with experience developing ML pipelines and infrastructure to build out the next-generation ML solutions to power use cases across the company. Across the team, we employ methods ranging from simple heuristics to Deep Learning technology to improve our performance and services. We're also excited to explore new directions with the team to continue pushing the boundaries of what's possible.

Our ML Engineers work in close collaboration with Data Scientists, ML Modelers and Software Engineers from across Cash App. Check out our Machine Learning / AI blog here !
