[Hiring] Senior Blockchain Developer @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
• Service marketplaces
• Full-stack development environment (DevHub)

This role reports to the engineering leads. Autheo’s Layer-0 coordination layer is Cosmos-based, with IBC interoperability and an EVM-compatible execution environment. We are recruiting a senior blockchain developer who has written production chain code in Go, Rust, or Solidity — modules, nodes, contracts, IBC or bridges, and the tooling other teams build on.

This is hands-on engineering, not advisory work. You will:

• Write and review the code that runs the chain and the services around it
• Own changes from design to upgrade
• Build the tools that make Autheo easy for builders to start on

Qualifications

• Public blockchain code you wrote
• Merged pull requests or a public repository in Go, Rust, or Solidity — a chain, node, contract, bridge, wallet, or developer tool
• 5+ years of production software engineering, with substantial blockchain work in at least one of Go, Rust, or Solidity
• Hands-on work in at least one of: Cosmos SDK modules, an EVM or Solidity contract surface, IBC or bridges, or chain/node operations
• Comfortable operating your own work: Linux, Docker, Kubernetes, CI pipelines, full nodes or validators, and Prometheus/Grafana monitoring

Requirements

• Experience across more than one of Go, Rust, and Solidity
• IBC relayer operation (Hermes, the Go relayer, or equivalent) or bridge engineering
• Wallet, custody, or signing infrastructure
• Developer tooling other engineers depend on: a CLI, SDK, code generator, or scaffold
• Teaching, conference talks, or workshops on blockchain engineering

First 90 Days

• A written review of one Autheo surface you are best placed to own (a module, an EVM path, an IBC or bridge path, or a node/tooling area): what is current, what lags, and what is at risk, agreed with the engineering leads
• At least one chain, contract, or interoperability change shipped through testnet rehearsal, with tests
• One developer-tooling improvement in DevHub, used by another team

Compensation & Growth Path

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.

Company Description

Autheo is building a Layer-0 Operating System and an integrated Layer-1 so identity, compute, storage, developer tooling, and AI sit on one network instead of a pile of bridges. The work now is product and protocol: making that network faster, safer, and ready for the builders and businesses that will run on it.
