[Hiring] Senior DeFi Protocol Engineer @Launch Legends

Role Description

We’re offering a unique opportunity to join Launch Legends (and Autheo) as a part-time Equity Cofounder. Founded in July 2021, Launch Legends is at the forefront of bridging Web3 blockchain technology with the next evolution of Web2 integration—bringing businesses on-chain through enterprise-grade solutions, DePIN innovations, and decentralized financial infrastructure.

Our flagship project, Autheo, is an AI-enabled Layer-0 Operating System with an integrated Layer-1 blockchain and complete decentralized infrastructure that includes decentralized compute, storage, identity, and service marketplaces, as well as a full-stack development environment (DevHub)—engineered for scalable enterprise adoption, developer innovation, and real-world blockchain integration.

Qualifications

• Public protocol code you wrote.
• Merged pull requests or a public repository for DeFi, chain, wallet, or tooling work in Solidity, Rust, Go, or Move.
• 5+ years of production software engineering, including substantial blockchain or DeFi work.
• DeFi or on-chain market work that shipped: automated market makers, staking, vaults, reward distribution, or equivalent protocol logic.
• Multi-chain experience: Cosmos and EVM, IBC or bridges, or work that spans more than one execution environment.
• Comfortable operating your own work: Linux, Docker, Kubernetes or equivalent CI, testnet deployments, and monitoring.

Requirements

• Design, build, and review DeFi protocol logic for Autheo: staking and fee mechanics, vaults, automated market makers, reward distribution, or equivalent market primitives.
• Write upgrade paths and migrations that are deterministic, tested, and rehearsed on testnet before they ship.
• Build and review IBC, bridge, or cross-environment paths that DeFi protocols depend on.
• Work on wallet, custody, or signing flows that DeFi users and builders need.
• Unit, fork or simulation, and invariant or fuzz tests for every protocol change.
• Run what you ship: testnet deployments, and monitoring that explains a failed transaction or an unexpected state change.

Benefits

• This is a part-time equity / token-based cofounder opportunity.
• You will receive equity in Launch Legends, Autheo, and the WFO Creator Network, along with token allocations in the Autheo blockchain.
• There is no cash salary for this role, and the commitment is at least 20 hours per week.

First 90 Days

• A written review of Autheo’s DeFi and value-transfer surfaces: staking and fees, vault or market primitives, and cross-environment paths.
• At least one protocol change shipped through testnet rehearsal, with tests.
• One wallet, custody, or DevHub tooling improvement that another team can use.
• A documented IBC, bridge, or cross-environment path that a DeFi builder can follow.
