Senior Go Protocol Engineer â Autheo | Cosmos SDK Modules, IBC & Chain Developer Tooling

Shape the Future of BlockchainBringing Business On-Chain

Were 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 integrationbringing 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.

Our Projects

• Autheo
• Docs
• Autheo Team Legends (Parent Company)
• X / Twitter Autheo

  With nearly 100 equity cofounders from leading companies and institutionsmany with advanced degrees and PhDsAutheo is solving the critical challenges blocking business adoption of blockchain technology.

  Autheos Layer-1 network staking and fee model and DevHub builder environment are being built and strengthened alongside sovereign identity (TheoID) decentralized compute and persistent storage through the Autheo Marketplace AI inference (THEO AI) and post-quantum cryptography.

  Key Features

  • Layer-0 OS Layer-1 Sovereign Cosmos-based coordination layer with an EVM-compatible execution environment IBC interoperability and Proof of Autheo consensus.
  • Eigensphere Engine Multi-language runtime. Rust is a first-class path for execution cryptography and developer tooling alongside Go Solidity Move Vyper and C.
  • DevHub & full-stack SDKs One workspace for frontend backend smart contracts and orchestration.
  • TheoID Sovereign identity for people services and AI agents with a post-quantum roadmap (NIST-standardized ML-KEM ML-DSA and SLH-DSA).
  • Autheo Marketplace Decentralized compute storage and service markets built into the Autheo network.
  • THEO AI Inference and agent orchestration as a native primitive not a third-party bolt-on.
  • DePIN infrastructure On-chain networks for real-world infrastructure ownership and resource sharing.

  Audits & Organization

  • Audits: Halborn (testnet and validator node platform) CertiK (Layer-1 chain and smart contracts) Adevar Labs (Base to Autheo bridge).
  • Token: THEO the native utility coin of the Autheo network.
  • Organization: Launch Legends Inc. a Wyoming corporation parent of Autheo LLC. Stewarded in part by the Autheo Foundation. 100 equity cofounders across 25 countries.

  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. We have already completed an initial financing round to support infrastructure and marketing and are currently in discussions with VCs and crypto investors to fund expansion. There is no cash salary for this role and the commitment is at least 20 hours per week.

  ROLE: Senior Go Protocol Engineer Autheo Layer-0 / Layer-1 Cosmos SDK Modules IBC & Chain Developer Tooling Job code: LA393

  About the Role

  This role reports to the engineering leads.

  Autheos Layer-0 coordination layer is Cosmos-based with IBC interoperability and an EVM-compatible execution environment. We are recruiting a senior Go engineer who has written protocol code inside real chains: Cosmos SDK modules IBC paths upgrade handlers and the developer tooling other teams build on.

  This is hands-on engineering not advisory work. You will write and review the Go that runs the chain own changes from design to upgrade and build the tools that make Autheo easy for builders to start on.

  1. Chain modules and protocol logic

  • Design build and review Cosmos SDK modules for Autheos staking and fee model reward distribution validator rules and governance.
  • Write state migrations and upgrade handlers that are deterministic tested and rehearsed on testnet before they ship.
  • Keep the chains modules current with upstream Cosmos SDK CometBFT and IBC-Go releases.

  2. IBC and interoperability

  • Own IBC paths end to end: channel setup transfers and memos light-client and misbehaviour handling and relayer operation (Hermes the Go relayer or equivalent).
  • Work with the bridge and EVM teams so assets and messages move between Autheos execution environments with clear failure modes.

  3. Developer tooling and DevHub

  • Build and maintain Go tooling builders actually use: CLIs Protobuf and gRPC code generation module scaffolding and SDK migration tools.
  • Turn protocol changes into tooling and docs so a developer can scaffold test and deploy on Autheo from DevHub without help.

  4. Testing release and operations

  • Unit simulation and end-to-end tests for every module change; CI that builds tests and blocks a bad release.
  • Run what you ship: testnet nodes and validators Kubernetes deployment and Prometheus / Grafana dashboards that explain a failure without guesswork.

  Required

  • Public Go you wrote inside a blockchain codebase. Merged pull requests to Cosmos SDK CometBFT IBC-Go a Cosmos SDK chain go-ethereum or an equivalent protocol repository. We read the code before we read the resume. Applications without a link to blockchain Go code you wrote yourself will not be reviewed.
  • 5 years of production Go: concurrency context cancellation worker pools batching and performance problems you have debugged under load.
  • Cosmos SDK module work that shipped on a public network: keepers message servers genesis state migrations or upgrade handlers in staking distribution governance or fee logic. Name the chain the module and your part in it.
  • Hands-on IBC: transfers channels light clients misbehaviour handling or relayer integration and operation. Link the change or the relayer setup you ran.
  • Developer tooling other engineers depend on: a CLI code generator Protobuf / gRPC pipeline scaffolding or SDK migration tool. Link the repository or release.
  • Comfortable operating your own work: Linux Docker Kubernetes CI pipelines full nodes or validators and Prometheus / Grafana monitoring.

  Preferred

  • Maintainer or top-contributor status on a public blockchain repository.
  • EVM experience next to Cosmos: Cosmos EVM integration Solidity contracts you deployed or Go services calling contracts through ABI bindings.
  • Ethereum Layer 2 or zk-rollup engineering (transaction selection proof submission L2 signing).
  • Wallet custody or signing infrastructure: key handling hot / warm / cold wallet flows multi-chain transaction tracking.
  • Multi-chain indexing or block-explorer back ends that you operated in production.
  • CosmWasm or Rust experience (a plus not required).
  • Teaching conference talks or workshops on blockchain engineering.

  First 90 Days

  • A written review of Autheos Cosmos SDK modules and IBC setup: what is current what lags upstream and what is at risk agreed with the engineering leads.
  • At least one module change or upgrade handler shipped through testnet rehearsal with simulation and end-to-end tests.
  • One IBC path or relayer workflow documented monitored and owned end to end.
  • One developer-tooling improvement in DevHub such as a scaffold code generator or CLI command used by another team.

  About Our Organization

  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.

  🌠🚠WHY JOIN LAUNCH LEGENDS

  • Build the core not a side project. Protocol DevHub TheoID and the Marketplace are being built and strengthened now and your work goes straight into them.
  • The Go Protocol seat owns Cosmos SDK modules IBC paths and the chain tooling builders use in DevHub.
  • Equity in Launch Legends and Autheo plus a THEO token allocation.
  • 100 equity cofounders across 25 countries. Remote. Direct line to the engineering leads and the Managing Directors.
