Software Engineer, Backend, Comms Platform

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. About the Role Every approval request, receipt reminder, payment alert, and card notification Ramp sends has to reach the right person, on the right channel, at the right time. When it does, finance teams close faster and employees spend less time chasing tasks. When it doesn't, a missed message can mean a stalled approval, a late payment, or a flood of notifications nobody asked for. Ramp's Communications Platform team builds the shared system that every product team uses to reach customers. It handles transactional messages across email, SMS, push, Slack, Microsoft Teams, and WhatsApp, including templating, delivery, retries, digesting, user preferences, and delivery monitoring. The team also supports the conversational experiences that let customers work with Ramp directly from the channels they already use. We're looking for a backend engineer to own a core part of that platform. You'll take responsibility for an area such as message delivery and channel integrations, communication preferences, or platform reliability and scale, set its technical direction within the team, and keep it correct and dependable as message volume and the number of teams building on it grow. You'll work closely with product, design, and engineering partners across Ramp to make communications faster, more reliable, and easier for every team to build on. Responsibilities Own the design and evolution of a core part of Ramp's communications platform, from technical design through launch, monitoring, and iteration Build and extend integrations with messaging channels and delivery providers, including email, SMS, push, and workplace chat tools such as Slack and Microsoft Teams Design delivery workflows that are idempotent, retry safely, and confirm successful delivery, so customers reliably get the messages they need without duplicate sends Build communication preferences and controls that let users and administrators decide what they receive and where Make the platform simple and safe for other Ramp engineers to build on, with clear abstractions, strong defaults, and good developer tooling Improve the reliability, performance, and observability of the platform as message volume grows Drive technical direction for your area and raise the engineering bar through design reviews, code reviews, and mentorship Requirements Experience designing, building, and operating production backend systems, including APIs, data models, and asynchronous workflows A track record of owning a system or product area end to end and shaping its technical direction over time Strong system design judgment, especially around reliability, idempotency, and correctness in high-volume distributed systems Product sense: you care about the experience of the people receiving each message, not just the ticket, and you balance speed with quality Clear communication and a collaborative approach to technical decisions across product, design, and engineering Nice to Haves Experience building notification, messaging, or communications platforms Experience integrating with messaging
