Internship - Software Engineering - Winter/Summer 2026 na Slash Financial

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. We power over $10B in payments each year and generate 9 figures in revenue, while shipping fast and building products used by thousands of global businesses.

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. You’ll own the product vision, roadmap, and execution — translating complex financial systems into simple, reliable, and scalable experiences.
