The Company
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 evolved into 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 aim to redefine the world’s relationship with money, making 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
Machine Learning is integral to how we at Cash App design products, operate, and pursue our mission to serve the unbanked and disrupt traditional financial institutions. Our massive scale and deep trove of transaction data create numerous opportunities to use ML and AI methods to better understand our customers and offer new products and experiences that can improve their lives. We are a highly creative group that prefers to solve problems from first principles; we move quickly, make incremental changes, and deploy to production every day. As part of the Risk ML team, you will build machine learning models that detect fraudulent activity in real-time and help keep our customers safe and secure. You will experiment with state-of-the-art algorithms to drive down false positives, collaborate on new product features to reduce fraud losses, analyze emerging fraud patterns, engineer new features for risk models, and deploy robust models to take action on bad activity in real-time. This role can work remotely from anywhere in Australia or New Zealand, or from our offices in Melbourne, Sydney, and Auckland. You Will
Be responsible for building machine learning models to detect and act against fraudulent activity, researching emerging fraud patterns, and leading and participating in cross-functional initiatives to tackle problems. Collaborate cross-functionally with our engineering, product, and operations teams located across Australia and the United States (particularly Melbourne and San Francisco) to keep our customers and their money safe. Work closely with the ML Engineering teams who build the systems that allow our models to operate at scale and in real-time. Contribute to the growth of our modeling capabilities through mentoring and supporting fellow modelers. Exercise a high level of autonomy and responsibility, owning your solutions from design through to operation. You Have
Bachelor's degree in a quantitative field such as Mathematics, Statistics, Physics, or Machine Learning; Masters or PhD preferred. 5+ years of experience in machine learning, artificial intelligence, or a related field. Strong knowledge of machine learning algorithms and data analysis techniques. Excellent problem-solving skills and attention to detail. Strong communication skills, with the ability to explain complex concepts to non-technical stakeholders. Technologies We Use and Teach
MySQL, Snowflake, Tableau, Mode GCP/AWS Every benefit we offer is designed with one goal: empowering you to do the best work of your career while building the life you want. Block, Inc. (NYSE: SQ) is a global technology company with a focus on financial services. Made up of Square, Cash App, Spiral, TIDAL, and TBD, we build tools to help more people access the economy.
