Senior Engineer, Backend, Vendor Management

About Ramp Ramp is building the smart infrastructure for finance teams, embedded in the transaction flow of every dollar a business spends. We automate how over $275B in annualized spend flows in and out of 85,000+ companies: authorizing payments, flagging risk, categorizing spend, and closing books. The problems are high-stakes, data-dense, and unforgiving. We hire people with high agency and high urgency. We look for slope over intercept. We care less about where you trained and more about what you’ve built. At Ramp, everyone is a builder who owns problems end to end and makes consequential decisions that shape the outcome. The median Ramp customer saves 7.5% and grows revenue 16% in their first year – far in excess of businesses operating without Ramp. We believe every ambitious company deserves the same. If you want to build systems that directly shape how companies move and manage billions, Ramp is the place to do it.

Make vendor data available consistently across the products that depend on it, including procurement and bill pay. Own projects from problem definition and technical design through launch, monitoring, and iteration. Raise the quality of the team’s systems through thoughtful design reviews, code reviews, and mentorship. What You’ll Need Experience designing, building, and operating production backend systems, including APIs, data models, and asynchronous workflows. Strong judgment about data integrity, access controls, reliability, and the tradeoffs involved in evolving existing systems. A track record of independently leading complex engineering projects from design to production. Product sense and curiosity about how businesses and vendors actually use the workflows you build.
