Our mission is to increase the GDP of the internet and we have a staggering amount of work ahead. That means you have an unprecedented opportunity to put the global economy within everyones reach while doing the most important work of your career.
Machine Learning at Stripe
Machine learning is an integral part of almost every service at Stripe. Key products and use-cases powered by ML at Stripe include merchant and transaction risk payments optimization and personalization identity verification and merchant data analytics and insights. We are also using the latest generative AI technologies to re-imagine product experiences and are developing AI Assistants both for our customers and to make Stripes more productive across Support Marketing Sales and Engineering roles within the company.
Stripe handles over $1T in payments volume per year which is roughly 1% of the worlds GDP. We process petabytes of financial data using our ML platform to build features train models and deploy them to production. We use a combination of highly scalable and explainable models such as linear/logistic regression and random forests along with the latest deep neural networks from transformers to LLMs. Some of our latest innovations have been around figuring out how best to bring transformers and LLMs to improve existing models and enable entirely new product ideas that are only made possible by GenAI. Stripes ML models serve millions of users daily and reduce financial risk increase payment success rate and grow the GDP of the internet. We work on challenging problems with large business impact and seek to foster creativity and innovation.
About the team
Before Stripe every growing internet platform had a payments team. Today every growing internet platform has an Identity team to verify trustworthiness of a user. Identity verification is a core piece of economic infrastructure for online businesses that enables businesses to digitally verify the users Identity (through ID document Passport DL) for fraud regulatory and trust & safety purposes. At Stripe were building the future of identity verification and trust in the digital economy.
