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.

About the role

Slash is, at its core, a technology company and is on a mission to build the best engineering team in the world. We're building the smallest, smartest back office in fintech — and we’re hiring a Product Engineer for Backoffice Automation to help us get there. At Slash, we believe great internal systems — powered by automation, AI, and thoughtful UX — can replace layers of manual ops.

You’ll own internal tooling across admin dashboards, Slack bots, real-time notifications, and AI-assisted workflows that make our ops, support, risk, and compliance teams radically more efficient. This is a high-leverage, high-autonomy role where you’ll ship systems that let us scale without adding headcount — and set the gold standard for what an internal platform should be.

What you’ll be doing:

• Designing and building internal tools used daily by our operations and support teams

• Creating automation for key workflows — onboarding, approvals, limits, escalations, etc.

• Building AI-powered workflows with LLMs-in-the-loop — letting humans focus on judgment while software handles the rest

• Collaborating with product, ops, and engineering to identify pain points and solve them with software

• Maintaining high reliability and usability in everything you ship

We’re looking for someone who:

• Gets excited about building internal tools that feel like magic — fast, smart, and reliable

• Has experience across the stack and isn’t afraid to dive into unfamiliar problems

• Is excited about shipping practical use cases with AI Agents that drive real outcomes.

• Thrives in fast-paced, high-trust environments with a bias for shipping

• Cares deeply about impact, craft, and making others’ work dramatically easier

What's in it for You:

• Opportunity for high growth

• High autonomy + ownership culture

• Comprehensive health + benefits plan

• Working out of our downtown San Francisco office space 

• Unlimited Vacation
