Full Stack Engineer

ABOUT THE ROLE Join a small, senior team building enterprise AI infrastructure — specifically a platform that gives AI agents reliable, governed, real-time context over complex business data. As a Full Stack Engineer, you'll own product surfaces end-to-end, from the interfaces engineers and customers interact with to the APIs and data models powering them. Your work directly shapes how users understand and trust the platform. WHAT YOU'LL DO - Own complete product surfaces end-to-end: UI, APIs, and underlying data models. - Make complex distributed system behavior legible and fast through well-crafted interfaces and APIs. - Split your time roughly 60% on frontend and API layer work, 40% on backend services. - Define architecture, ship to production, monitor behavior, and own fixes when things break. - Make product and design calls independently — no handed-down specs or design files. WHAT WE'RE LOOKING FOR - 5+ years building and shipping full-stack applications in production. - Genuine full-stack capability — comfortable going deep on distributed systems while also crafting polished UIs. - Proficiency with modern frontend frameworks (React, Vue, or equivalent). - Backend service development experience in Python, Go, Node.js, Java, or equivalent. - Experience designing APIs and data models that expose complex backend behavior intuitively. - Strong architectural judgment — you can pick a direction, ship it, and own it in production. - Comfort with ambiguity; you thrive without detailed specs and take ownership of outcomes. - Experience with databases and data modeling for systems requiring real-time performance. - Nice to have: experience with knowledge graphs, semantic systems, or graph databases; distributed systems, real-time inference, or agent-based systems; developer-facing or infrastructure products; enterprise data integration. LOCATION On-site in San Mateo, CA. Visa sponsorship is available.
