Job Description

About ChaosChain: The Mission

ChaosChain is the accountability protocol for the on-chain AI economy. Today, AI agents are black boxes. It's impossible to cryptographically verify their actions, which prevents them from being trusted with high-value commercial work. We are solving this.

Our Triple-Verified Stack provides end-to-end cryptographic guarantees for autonomous agent workflows, turning black boxes into transparent, accountable services. We are building the foundational trust layer for the entire autonomous economy, and our live SDK is one of the first to integrate key standards like ERC-8004 and x402.

We are a small, deeply technical team shaping the future of decentralized intelligence, and we are looking for a founding engineer to build it with us.

The Role: What You'll Build

As our first engineering hire, you will be the technical cornerstone of ChaosChain. You will take our proven architecture and prototypes and lead the charge in building, testing, and deploying a production-ready, mainnet protocol. You will work directly with the founder to translate a powerful vision into secure, elegant, and scalable code.

This isn't just a coding job; you will be a co-architect of the trust layer for the future of the internet.

Your responsibilities will include:

  • Core Protocol Development: Design, build, test, and deploy our Solidity smart contracts, including the ChaosCore factory, StudioProxy architecture, and the RewardsDistributor engine.

  • Integrate Cutting-Edge Tech: Implement the off-chain components of our protocol, including communication via XMTP and permanent data storage on IPFS/Arweave for our Decentralized Knowledge Graph (DKG).

  • Ensure Security & Reliability: Write comprehensive tests (unit, integration, and fork tests), participate in security audits, and build robust monitoring and alerting for our production systems.

  • SDK & Tooling: Evolve our public Python and TypeScript SDKs into a world-class developer toolkit, ensuring they're powerful, easy to use, and drive adoption.

  • Protocol Architecture & Security: Work directly with the founder to shape the protocol's roadmap, research new primitives (TEEs, ZK), and maintain an obsessive focus on security through rigorous testing and audit preparation.

  • Partner Engineering: Collaborate directly with the engineering teams of our launch partners, like Gaia, EigenCloud and others, to ensure their agent ecosystems can seamlessly onboard and thrive on our platform.

  • Shape the Roadmap: Collaborate directly with the founding team to define technical strategy, prioritize features, and navigate the path from testnet to mainnet and beyond.

Who We're Looking For: The Ideal Candidate

We are looking for a product-minded protocol engineer who thrives on autonomy and wants to ship groundbreaking work.

Must-Haves:

  • Deep Solidity & EVM Expertise: You have demonstrable experience designing, building, and deploying complex, secure, and gas-efficient smart contracts. You are fluent in frameworks like Foundry or Hardhat.

  • Full-Stack Web3 Fluency: You are an expert in TypeScript/Node.js and have deep experience with libraries like Ethers.js/Viem, building SDKs, and interacting with L2s. Experience with backend services (e.g., Fastify, Postgres/Supabase) is crucial.

  • Protocol-Level Thinker: You understand concepts like cross-chain communication, transaction lifecycle, and the challenges of building on-chain + off-chain hybrid systems.

  • A Builder's Mindset: You have a portfolio (GitHub, side projects) that shows you love to build. You can take a high-level idea and ship a robust MVP in weeks, not months.

  • Technical Leadership & Ownership: You don't just write code; you lead technical decision-making. You are comfortable mentoring future hires, conducting code reviews, and making high-stakes architectural trade-offs without needing constant supervision. You treat the codebase as your own product.

  • Velocity with Precision: We need a builder who ships fast to get market feedback but never compromises on security/testing. They should balance "move fast" with "don't break the protocol."

  • First-Principles Thinking: We are inventing a new category. We need someone who solves problems by understanding the root mechanics (crypto/econ/AI), not just by copying existing patterns.

  • Excellent Communication: You can clearly articulate complex technical concepts to both technical and non-technical audiences.

Bonus Points (Nice-to-Haves):

  • Experience with Python, as our SDK and the agent ecosystem are Python-heavy.

  • Familiarity with The Graph for building subgraphs and indexing on-chain data.

  • A genuine interest in and understanding of the AI/LLM space.

  • Experience with Trusted Execution Environments (TEEs) or ZK primitives.

  • Experience building or integrating payment systems.

Why You Should Join ChaosChain

  • Build the Future: You won't be working on a derivative DeFi protocol. You will be building the foundational trust layer for the entire global autonomous economy. The work you do here will matter for decades.

  • Founding Equity & Impact: As a critical early hire, you will receive a significant equity/token allocation and have a direct hand in shaping our technology, product, and culture.

  • Work with the Best: You will work directly with the core innovators shaping standards like ERC-8004 and collaborate with leading ecosystems.

  • Solve the Hardest Problems: This is a role for those who are intellectually curious and want to solve the most challenging problems at the intersection of cryptography, economics, and artificial intelligence.

  • World-Class Ecosystem: We are deeply integrated with and respected by leaders in the space, including the teams at the Ethereum Foundation, EigenLayer, Chainlink, and more.
