Fullstack Engineer (SF, hybrid/on-site) | Trust & Payments Infra | Series A / Tier 1 VC Backing

A Series A San Fran startup backed by Tier-1 investors is building the identity and transaction layer for the agentic internet, the infrastructure that lets AI agents authenticate, pay, and operate autonomously at scale.

They're hiring a Fullstack Engineer (hybrid/on-site) to own the developer-facing side of the product: real-time dashboards, terminal interfaces, and the API layer that gives engineers and operators live visibility into how agents interact with the world.

What you'll be building:

• A high-performance web dashboard for managing AI agent identities and payments
• A CLI/TUI for developers to interact with agent infrastructure directly from the terminal
• APIs and frontend components handling real-time data streams from blockchain and backend services
• Custom integration layers for early design partners

What they're looking for:

• 3+ years in fullstack development at an infrastructure or developer-tooling startup
• Strong React and TypeScript — primary emphasis is on frontend and UX
• CLI or TUI experience (Bubble Tea, Charm, or similar)
• Backend proficiency, preferably in Go, Rust, or Node.js
• Product mindset
