Feedzai is the world’s first RiskOps platform for financial risk management, and the market leader in safeguarding global commerce with today’s most advanced cloud-based risk management platform, powered by machine learning and artificial intelligence. Feedzai is securing the transition to a cashless world while enabling digital trust in every transaction and payment type. The world’s largest banks, processors, and retailers trust Feedzai to protect trillions of dollars and manage risk while improving the customer experience for everyday users, without compromising privacy. Feedzai is a Series D company and has raised $282M to date. With a valuation of +$1.5B, the company's technology protects 900 million people in 190 countries. 

Feedzai Research focuses on anticipating and solving Feedzai’s long-term goals without the delivery pressure of product development. The Systems Research Team makes data-driven decisions to design and create new products like Railgun - a state-of-the-art engine to compute real-time metrics now used across Feedzai to process thousands of events per second with millisecond latencies at a scale that Kafka Streams or Flink could not handle - and Feedzai Genome - which gives a graph-view of fraud, allowing analysts to discover other fraud patterns and to tag fraud at scale. We thrive to develop ethical cutting edge technology that will stay one step ahead of the fraudsters of tomorrow. We work closely with Product and Data Science to build distributed systems that support high-load, operate 24/7 with low latencies, and use Machine Learning to make decisions and fight fraud more efficiently. As a research team, we focus on long-term, disruptive, state-of-the-art research, produce and protect our IP, publish peer reviewed work, contribute to open-source, and partner with external researchers and universities.

We think two years ahead, and we ask ourselves: How many clients will we have in one year? How will our platform perform going from 100 to 1000 clients? By thinking in faraway scales and working complex problems, we’re empowered to spark change every day, influencing the trajectory of our company and ourselves.

Formed by engineers and managed by engineers, at Feedzai you will find one of the most talented teams and a safe, open, and collaborative environment.
