Senior Rust Blockchain Developer â Autheo | Chain, Node, Smart Contracts & 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 Rust Blockchain Developer Autheo Internet Operating System Chain Node Smart Contracts & Tooling Job code: LA394

  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. Rust is a first-class path in the Eigensphere Engine for execution cryptography and developer tooling. We are recruiting a senior Rust engineer who has written production Rust in a real blockchain stack: the node smart contracts or a runtime and the tooling other teams build on.

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

  1. Chain node and protocol paths

  • Design build and review Rust components on the Autheo node: consensus-adjacent paths networking state sync or the execution environment.
  • Keep those paths deterministic tested and safe to upgrade and work with the Go and protocol teams where the stacks meet.
  • Instrument what you own so a failure can be explained from metrics and traces rather than guesswork.

  2. Smart contracts and execution

  • Write and review Rust smart-contract or runtime code (CosmWasm a Wasm-compatible runtime or an equivalent contract SDK) that other builders can use.
  • Own metering host interfaces and the invariants that keep contract execution deterministic and sandboxed.

  3. Developer tooling and DevHub

  • Build and maintain Rust tooling builders actually use: CLIs contract SDKs cargo-level build / test / deploy flows and templates in DevHub.
  • Turn protocol and runtime 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 property and end-to-end tests for every change; CI that builds tests and blocks a bad release. Benchmarks on hot paths so a regression fails the build.
  • Run what you ship: testnet nodes Kubernetes deployment and Prometheus / Grafana dashboards.

  Required

  • Public Rust you wrote in a blockchain or systems codebase. A GitHub / GitLab profile crate or merged pull requests to a node runtime contract SDK or equivalent. Include a link to code you wrote; its the first thing we read.
  • 5 years of production Rust: ownership lifetimes async (Tokio or equivalent) concurrency and performance problems you have debugged under load.
  • Hands-on work in at least one real blockchain node runtime or smart-contract stack written in Rust (Substrate CosmWasm a Rust ABCI or CometBFT stack reth Agave / Solana Sui / Aptos Fuel a Wasm runtime or equivalent). Name the repository and your part in it.
  • Developer tooling or libraries other engineers depend on: a CLI SDK crate or cargo-level toolchain. Link the repository or release.
  • Comfortable operating your own work: Linux Docker Kubernetes CI pipelines full nodes or validators and Prometheus / Grafana monitoring.

  Preferred

  • Contributions to a public Rust blockchain runtime cryptography or tooling repository.
  • Cosmos SDK IBC or CosmWasm work next to Rust.
  • Smart-contract language VM or Wasm runtime experience (wasmtime wasmer revm Move or equivalent).
  • Applied cryptography in Rust (signatures keys or NIST ML-KEM / ML-DSA / SLH-DSA) a plus not required.
  • Teaching conference talks or workshops on Rust or blockchain engineering.

  First 90 Days

  • A written review of Autheos Rust surface: node execution contracts and tooling what is current what is stubbed and what is at risk agreed with the engineering leads.
  • At least one node runtime or contract-path change shipped through testnet rehearsal with tests and CI coverage.
  • One developer-tooling improvement in DevHub such as a CLI command SDK release or template used by another team.
  • A benchmark in CI for one hot path you own.

  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 Rust Blockchain Developer seat owns Rust on the node the contract and runtime path and the 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.
