Data Science Engineer Jobs at SentiLink with Visa Sponsorship

INTRODUCTION

SentiLink provides innovative identity and risk solutions, empowering institutions and individuals to transact with confidence. We’re building the future of identity verification in the United States, replacing a clunky, ineffective, and expensive status quo with solutions that are 10x faster, smarter, and more accurate. We’ve seen tremendous traction and are growing extremely quickly. Our real-time APIs have helped verify hundreds of millions of identities, starting with financial services and rapidly expanding into new markets. SentiLink is backed by world-class investors including Craft Ventures, Andreessen Horowitz, NYCA, and Max Levchin. We’ve earned recognition from TechCrunch, CNBC, Bloomberg, Forbes, Business Insider, PYMNTS, American Banker, LendIt, and have been named to the Forbes Fintech 50 list every year since 2023. Last but not least, we’ve even made history - we were the first company to go live with the eCBSV and testified before the United States House of Representatives on the future of identity. SentiLink supports a variety of ways to work, ranging from fully remote to in-office. We operate as a digital-first company with strong collaboration across the U.S. and India. We maintain physical offices in Austin, San Francisco, New York City, Seattle, Los Angeles, and Chicago in the U.S., and in Gurugram (Delhi) and Bengaluru in India. If you’re located near one of these offices, we would love for you to spend time in the office regularly. Some roles are hybrid or in-office by design. For example, our engineering team in India works primarily from our Gurugram office.

ROLE

We’re looking for a founding Senior Machine Learning Engineer to help scale and operationalize our ML systems end-to-end. This is a highly technical role focused on building the infrastructure, tooling, and processes that allow our Data Science team to develop, deploy, monitor, and iterate on machine learning models efficiently and safely. This person will be a foundational owner of our ML platform and will define the interfaces between Data Science, Engineering, and Infrastructure. You’ll work on systems that power real-time production ML, ensuring we can confidently ship models, measure their impact, and detect issues early. This is a high-ownership role for someone who wants to build ML systems that power real-world fraud prevention at scale.
