### About GenLayer Labs

GenLayer Labs is a decentralized AI research collective building the trust infrastructure for the AI Age. We are the developers of GenLayer—an open, AI-driven Court of the Internet—a synthetic jurisdiction where autonomous agents and protocols can reason, transact, and govern at machine speed with sovereignty, transparency, and trust. Our infrastructure enables autonomous agents and smart contracts to access live web data, interpret natural language, and resolve disputes using AI consensus.

Backed by Maelstrom (Arthur Hayes), Arrington Capital, and North Island Ventures, we’re defining a new category of decentralized infrastructure: trustless decision-making for the AI age.

### Role overview

We are hiring an **AI-First Developer / Builder** to work on prototypes, tools, and internal systems that push the boundaries of what intelligent contracts and AI-enabled infrastructure can do.

This role is ideal for someone who:

-   enjoys **building quickly.**
-   is comfortable with **ambiguity and experimentation.**
-   uses **AI agents as part of their daily workflow.**

-   Work with **LLMs, agents, and RAG pipelines.**
-   Prototype **AI-assisted developer workflows.**
-   Experiment with new **AI capabilities for intelligent contracts.**
-   Design small **full-stack applications** (backend + simple frontend).
-   Use **AI copilots and agents extensively in development.**
-   Collaborate closely with a small team to rapidly test and iterate on ideas.
