Senior Fullstack Engineer

We are building a fully managed SaaS platform in the AI infrastructure space. The platform provisions and manages dedicated AI agent instances for end customers across multiple cloud providers — removing all DevOps complexity behind a clean web dashboard and mobile app. The project has an existing working prototype and we are looking for an engineer who can move fast, ship quality features, and hit the ground running.

What we're looking for
 

• Strong hands-on experience with React 18, Vite, TanStack Query, and Zustand
• Backend development with Node.js 22+ — REST APIs, WebSocket, async flows
• PostgreSQL with a type-safe ORM (Drizzle or similar)
• Firebase Auth — custom token flows, ID token verification, session management
• Familiarity with cloud provider APIs such as Hetzner, DigitalOcean, or Vultr
• Experience with SSH automation and cloud-init provisioning scripts is a strong plus
• React Native / Expo experience is a plus but not required
• Ability to read a detailed technical specification and execute against it independently

Key requirement
You must be comfortable working with AI coding tools — especially Claude Code — as a core part of your development workflow. We expect engineers to move fast by pairing with AI effectively: writing clear prompts, reviewing output critically, and iterating quickly. Experience with Claude, Cursor, or GitHub Copilot is required.

Tech stack
React 18, Vite, Zustand TanStack Query, shadcn/ui, Tailwind CSS, Framer Motion, Hono.js, Node.js 22+, Drizzle ORM, Neon PostgreSQL, Firebase Admin, Hetzner Cloud, DigitalOcean, Vultr, Cloudflare DNS, cloud-init, Polar, Resend, React Native, Expo

Nice to have
 

• Experience with real-time WebSocket protocols and streaming data
• Familiarity with AI agent platforms or LLM orchestration layers
• Background in managed hosting products or DevOps automation
• App Store / Play Store submission experience via Expo
