Founding Principal Engineer

Full-time/Company: Joyride

Joyride is building the first dedicated 0DTE options exchange to provide better leverage for crypto traders. Derivatives present the single largest opportunity to bring traditional finance on-chain with over $3.5 trillion dollars of notional volume traded in the U.S. every day. 

What you will build:

The Trusted Matching Engine: Architect a high-frequency Central Limit Order Book (CLOB). It must handle massive throughput without the latency drag of a blockchain while maintaining verifiability.

The Trust Bridge: Design the cryptographic system that proves to the blockchain that the off-chain match was valid. We must ensure that the exchange operators cannot front-run or alter the order book.

Atomic Settlement: Write the programs that handle the movement of collateral based on the proofs generated by your off-chain engine.

Risk & Liquidation: Build a real-time risk engine capable of liquidating 0DTE positions instantly to protect the protocol from bad debt, even during high network congestion.

Who you are:

High-Performance Systems Expert: You understand exactly how your code maps to hardware. You prioritize memory layouts, lock-free data structures, and concurrency patterns to squeeze every cycle out of the CPU.

Architectural Polymath: You are comfortable traversing the gap between high-performance cloud infrastructure and trustless state machines.

Security Minded: You think like an adversary. When you see a “hybrid” architecture, your first thought is “How do I break the link between the server and the chain?”

Requirements:

- 5+ years of backend systems engineering (Rust, C++, or Go)
- Deep proficiency with Rust
- Familiarity with Solana and EVM development
- Knowledge of event-driven architectures and asynchronous programming

Founding Protocol Engineer (Web3 + AI)

Full-time/Company: Nethermind

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.

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.

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.
