Product Engineer: Core Banking

About Slash

Slash is building the future of business banking, one industry at a time. We believe businesses deserve financial infrastructure tailored to how they actually operate. That's why we're creating a new category of business banking. We combine the reliability of traditional banking (high yields, competitive rewards, and comprehensive security) with industry-specific features that make businesses more efficient, more competitive, and more profitable.

Started in 2021, Slash is one of the fastest growing fintechs in the world and we power over three billion dollars a year in business purchasing across numerous industries. We're backed by some of the best investors in the world including Menlo Ventures, NEA, Y Combinator, Stanford University, and the founders of Tinder and Plaid. Slash is headquartered in San Francisco, and has a strong in-person culture.
