About OpenBuilder
About the role

The Company

We’re building a web-based AI app builder that lets non-technical users create and deploy real applications without writing code. Our users expect things to “just work”—which means the platform underneath must be fast, reliable, and invisible.

We’re an early-stage, YC startup building a small, high-ownership founding team.

The Role

We’re hiring a Founding DevOps Engineer to own infrastructure, reliability, and operational excellence from day one. This is a staff-level role with architectural authority and long-term impact.

You’ll design systems that support AI-powered workloads, rapid iteration, and a product where non-technical users never think about infrastructure—yet can get instant help when something goes wrong.

Human-in-the-Loop Infrastructure (What Makes This Role Unique)

A core differentiator of our product is a human-in-the-loop marketplace.

When a user’s app breaks or behaves unexpectedly, a vetted human developer can instantly jump into that user’s running VM, diagnose the issue, and fix it in real time—often before the user even understands what went wrong.

As a founding DevOps engineer, you will:

  • Design secure, auditable VM access for third-party human developers
  • Build fast, safe workflows for live debugging and remediation
  • Integrate deep observability so humans can act with full context
  • Ensure isolation, permissions, and trust boundaries are rock-solid

This system is powered by strong observability and tooling, including Sentry-style error tracking, logging, metrics, and traces that tie user-visible issues directly to infrastructure and code.

What You’ll Do

  • Own production infrastructure, deployments, and reliability
  • Architect scalable systems for a high-growth AI web platform
  • Design CI/CD pipelines that optimize for safety and speed
  • Operate and scale VM-based workloads
  • Build observability that reflects real user impact (errors, latency, failures)
  • Lead incident response, postmortems, and long-term reliability improvements
  • Set standards for security, backups, disaster recovery, and performance
  • Work closely with product engineers to reduce operational complexity
  • Help define engineering culture and best practices as the team grows

Tech Stack

  • TypeScript, React
  • Django
  • PostgreSQL
  • Fly.io** (VM-based deployments)**
  • Google Cloud Platform
  • Cloudflare
  • Nginx
  • VSCode Web
  • Observability: Sentry-style error tracking, logs, metrics, tracing

What We’re Looking For

  • 3+ years of experience in DevOps, SRE, or infrastructure engineering
  • Proven ownership of production systems at scale
  • Strong Linux, networking, and web infrastructure fundamentals
  • Experience running PostgreSQL in production
  • Cloud experience (GCP preferred)
  • Comfort designing secure systems with live access and trust boundaries
  • Product-oriented mindset for non-technical users
  • Ability to make architectural decisions in ambiguous, early-stage environments
  • Clear communicator who can explain complex systems simply

Nice to Have

  • Founding or early-stage startup experience
  • Backend engineering background (especially Django)
  • Experience with Cloudflare, edge platforms, or AI workloads
  • Experience designing internal tooling or support platforms

Why Join

  • Founding engineer role with deep ownership and influence
  • Build a genuinely differentiated AI product
  • Solve hard infrastructure problems with real user impact
  • Close collaboration with founders
  • Competitive salary + meaningful equity
  • Shape the technical foundation from day one
