Customer Engineer

RevenueBase: We're building the data infrastructure that makes AI agents trustworthy instead of error-prone. We provide continuously refreshed, verified B2B data for autonomous AI agents and GTM workflows. We've tripled growth while maintaining 100% gross dollar retention and staying cashflow positive. We power AI agents for Clay, Zoominfo, Dun & Bradstreet, and the next generation of AI GTM tools. Why We're Hiring This Role: The companies building the future of go-to-market are building on top of our B2B data infrastructure. Many are onboarded and running. The hardest part of being a B2B data customer is figuring out how to run the right searches across the data to get the business outcome they bought us for. They need a technical partner to help them actually succeed with the product. This role exists to own the full customer lifecycle — onboarding, activation, health, and expansion — across every account we have. You are the founding hire for this function. When we hire behind you, you hire them. What You'll Do: Own the "first successful search" — every new customer's activation milestone. Get them there, fast. This is the most important thing you do. Own customer health across all accounts. Know which customers are getting value, which are quiet, and which are at risk — before anyone asks. Drive expansion and cross-sell. As we ship new API surface area (verification, enrichment, discovery, MCP), identify which customers need what and run the expansion conversation. Ru
