Job Description
<p>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.</p>
<p>Coast is competing and winning with software, and we are building a world-class engineering team.

The role will work closely with our Product Engineering, and the CTO; this role reports to the Head of Platform.</p>
