Data Engineer

Coast is re‑imagining the trillion‑dollar U.S. B2B card payments infrastructure, with a focus on the country’s 500,000 commercial fleets, 40 million commercial vehicles, and many million commercial drivers. The incumbent technologies that cater to these customers are decades old, and drivers, fleets, and the merchants that serve them all increasingly demand modern digital experiences and affordable and transparent financial services products.

Coast's mission is to deliver them at a transformational scale, and to improve working lives in one of the country’s biggest industry sectors. The company is backed by top fintech and mobility venture funds.

In order to maximize our engineering velocity, we are hiring in NYC and the tri‑state area only. Our office is located in the heart of Manhattan’s SoHo neighborhood, benefiting from its vibrant creative energy. We come to the office on average four days a week.

At Coast, the success of our data platform is driving accelerating demand from all corners of the company. We’re looking for a key builder to help us meet this moment. In this role, you will drive the delivery of high‑impact analytics and AI use cases while contributing to the evolution of our modern, cloud‑native data platform. This is a chance to join a small, high‑leverage team and make a definitive impact, building the systems that help us understand risk, acquire customers, and create a better financial product.

You will be building on a solid foundation that lets you focus on high‑impact work from day one. Our data engineering organization follows the federated model of data product ownership—the data platform serves as the foundation, not the first line of defense against data issues.

This role is a launchpad for the next step in your career. You'll partner directly with business leaders and have outsized ownership, helping to steer the company's direction. This role reports to the Lead Data Engineer that heads up our Data organization.
