Senior DeFi Engineer - Primitives (with Blockchain Experience)

Launch Legends•Cheyenne, WY

About The Position

We’re offering a unique opportunity to join Launch Legends (and Autheo) as a part-time Equity Cofounder. Founded nearly four years ago, 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-Zero OS with an integrated Layer-1 blockchain and complete decentralized infrastructure thast includes decentralized compute, storage, identity, and service marketplaces, as well as a Full-stack development enveronment (DevHub)—engineered for scalable enterprise adoption, developer innovation, and real-world blockchain integration. Autheo is building a sovereign data platform unifying petabyte-scale pipelines, federated lakehouse analytics, and 200GB/s streaming with 25μs query latencies, unbreakable encryption, and GDPR/HIPAA compliance. As a part-time Senior DeFi Engineer - Primitives in an equity-based cofounder role, you’ll design core DeFi mechanisms using Solidity, Rust, and Polkadot JAM, powering adaptive AMMs, perpetuals, and zk-enabled lending across DePIN networks. This role is critical to enabling post-quantum security and cross-chain liquidity at scale. If you’re passionate about DeFi primitives and Web3, join us to shape the financial layer for the next trillion-dollar decentralized economy.
