About the Role

A high-bar, fast-growing AI startup is hiring a Founding Backend Engineer to build the core systems behind an agentic AI product in the design space.

This is a true 0→1 role with full ownership from day one. You will work directly with founders to design and scale backend systems powering AI generation, orchestration, and product workflows.

The team is small, well-funded, and moving fast. Scope is unbounded.

What You’ll Do

  • Build backend systems for agentic AI workflows and code generation
  • Design infrastructure for parallel AI execution and complex state management
  • Own architecture across APIs, services, and core platform systems
  • Work with Puppeteer / Chromium for automation workflows
  • Integrate LLMs (OpenAI, Anthropic, Gemini) into production systems
  • Ship end-to-end features with high ownership and speed

Who You Are

  • 6+ years backend engineering experience (Senior II / Staff level)
  • Proven 0→1 builder (startup, founding engineer, or equivalent)
  • Experience building complex backend systems in production
  • Background in startup or high-intensity environments (e.g. Cruise, xAI)
  • Strong ownership and ability to operate with minimal structure
  • Willing to work onsite in San Francisco (5 days/week)

Tech Stack

  • Node.js / Express
  • Next.js (server actions)
  • AWS (Terraform, Pulumi)
  • Puppeteer / Chromium
  • LLM APIs (OpenAI, Anthropic, Gemini)

Key Requirements (Non-Negotiable)

  • 6+ years experience
  • Clear 0→1 ownership
  • Startup or equivalent high-intensity background
  • Hands-on with:
  • Express / backend systems
  • AWS infrastructure
  • Puppeteer / browser automation
  • LLM / agentic systems

Why This Role

  • Foundational hire — your work defines the system
  • Staff-level scope immediately
  • 0→1 build in a frontier AI category
  • High ownership, no bureaucracy
