## What you'll work on

As a founding engineer, you help design the engine and set product priorities with the founders.

- Build and improve the incremental engine that keeps context fresh for agents.
- Rethink the infrastructure and interactions that help agents and humans work together.
- Enable agents to share findings, respond to changes, and resume work when needed.
- Work with the founders to shape the product's direction and the company's culture.

## What we're looking for

Four core qualities. Infrastructure experience is a bonus.

### Taste for developer tools

Choose tools that solve developer problems.

Explain a product decision, the alternatives you considered, and how developer feedback changed your approach.

### Logical thinking

You reason through complicated systems and stay logically consistent.

Break a system into parts, trace state changes, and test assumptions. Explain how you verify code, including AI-generated code.

### Ownership

Take responsibility for a project from design through production.

You have taken a product from development to production. A project or team has relied on your technical judgment.

### Curiosity

You want to understand what happens underneath the interface.

Describe a surprising result you investigated, what you learned, and how it changed the system.

### Infrastructure experience Bonus

A plus, not a requirement.

Experience with databases, compilers, runtimes, distributed systems, or developer tools helps. Explain a correctness, performance, concurrency, or recovery tradeoff you handled.

## About us

CocoIndex is an open-source incremental engine, with a Rust core and a Python API, that keeps derived data current as its inputs change. We are extending it into the infrastructure that lets agents build on each other's work.
