Job description:
**Cua is building the infrastructure that lets general AI agents safely and scalably use Computers and Apps like humans do.**
With **8.9k
- GitHub stars in just 4 months** and backing from **Y Combinator**, we’re providing:
* An open-source framework for building and evaluating general-purpose AI agents
* A cloud container platform for sandboxed, scalable agent execution environments
* A blueprint for what production-grade general agent systems should look like
- backed by research
We're looking for our **first Founding Engineer** to help us push this vision forward
- turning cutting-edge research prototypes into real, deployable systems.
If you’re obsessed with developer tools, infrastructure, and making AI agents go from toy demos to robust, real-world tools
- we want to talk.
* * *
### 🛠️ What You'll Work On
* **Day 1 Impact**
- Ship infrastructure powering real agent workloads used by early customers and open-source users.
* **Agent Infra Core**
* OS-level sandboxing and container orchestration across cloud providers
* Scalable infrastructure for deploying isolated Linux/macOS environments for agents
* Tools that make agent deployment as simple as an API call
* **Beyond Engineering**
* **Open Source Leadership**
- Shape our growing GitHub community and help define the standard for AI agent systems
* **Product Strategy**
- Work directly with the founders on roadmap and direction
* **Dev Advocacy**
- Help grow the ecosystem with blog posts, community engagement, and in-person events in SF
* * *
### 🎯 You’re a Fit If You…
* **Live and breathe systems**
- You know how to scale infra, secure containers, and debug hairy cloud issues.
* **Build for abstraction**
- You’re excited about designing simple APIs over complex infrastructure.
* **Care about quality**
- You understand why reproducibility, isolation, and reliability are core to agent workloads.
* **Think long-term**
- You’re not here to build another wrapper
- you’re here to define a category.
* * *
### 🎓 What You Bring
* BS in CS (or equivalent experience)
- 2
- years shipping real systems in **Python, Go, TypeScript, or Rust**
* Infra experience: building secure, scalable, performant backend systems
* Familiarity with LLM-generated code and tools (e.g. Copilot, Cursor)
- and how to work with or around them
* Ability to navigate ambiguity and move fast without breaking the wrong things
**Bonus points for:**
* Deep experience with Docker, KVM, or OS virtualization
* Multi-cloud experience (GCP, AWS, Azure)
* PostgreSQL optimization war stories
* Meaningful open-source contributions
* * *
### 💼 What We Offer
* **Stage**
- Backed by YC and top investors, building the founding team
* **Location**
- SF-based, hybrid preferred, remote-friendly
* **Comp**
- $100K–$150K base
- **0.5% equity**
* **Timing**
- Join early enough to shape product, culture, and architecture from the ground up
* **Impact**
- Thousands of developers already use Cua; you’ll help define how agents run in production
* * *
### 🧪 How to Apply
* Your GitHub (required)
* A short note about the hardest infra problem you’ve solved
* Bonus: Fix an issue or build something with Cua
- our open-source project is active and ready
