Senior Infrastructure/Platform Engineer

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 ten billion dollars a year in business purchasing across numerous industries. We recently raised a $100M Series C led by Ribbit Capital with participation from Khosla Ventures, Goodwater Capital, NEA, and Y Combinator, accelerating our expansion into new markets and products.

Slash is headquartered in San Francisco, and has a strong in-person culture.

Slash is, at its core, a technology company and is on a mission to build the best engineering team in the world. We’re looking for a Senior Infrastructure/Platform Engineer focused on owning and scaling the foundation of our banking platform as we grow fast.

You’ll be responsible for keeping our systems reliable, secure, and fast — while building the tooling and infra that enables the rest of the team to move quickly without breaking things. That means scaling and working on everything on the cloud (AWS, Terraform, Kubernetes).

You’ll define our infrastructure roadmap, own critical decisions around performance, observability, security, and deployment, and play a key role in enabling Slash to serve billions of dollars in business spend reliably and securely.
