About Autheo

With nearly 100 equity cofounders from leading companies and institutions—many with advanced degrees and PhDs—Autheo is solving the critical challenges blocking business adoption of blockchain technology.

Autheo Mainnet has been live since May 14, 2026 (Chain ID 2127). Staking and transaction fees are operating on-chain. DevHub is available to builders. Sovereign identity (TheoID), decentralized compute and persistent storage through the Autheo Marketplace, AI inference (THEO AI), and post-quantum cryptography are rolling out on Mainnet.

THEO is live. This role starts after mainnet, not before it.

THEO is Autheo’s native utility token, not a governance token. Autheo is not a DAO.

As Of October 2, 2026, THEO Trades On Four Autheo-verified Markets Across Two Chains And One Centralized Exchange, With Enflux Supporting Liquidity Across The Venues

• THEO/USDT on MEXC — first centralized order book, opened October 1, 2026 at 13:00 UTC. Deposits are accepted on Autheo Mainnet (native THEO). Withdrawals opened October 2, 2026 at 13:00 UTC.
• THEO/USDC on Hydrex (Base) — live since August 20, 2026. Official Base contract: 0xebE516a20238F79dc20b07eaD6768e08891Ed309
• THEO/USDG on Uniswap v3 (Robinhood Chain) — live since September 10, 2026
• THEO/NVDA on Uniswap (Robinhood Chain) — live since September 24, 2026. Official Robinhood Chain contract: 0x3dc751e0da01812e6d9143cc696e7f07ea94da48

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.
• 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 (Kyber, Dilithium, Falcon / NIST ML-KEM, ML-DSA, SLH-DSA).
• Autheo Marketplace — Decentralized compute, storage, and service markets rolling out on Mainnet.
• 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.

Traction

• Mainnet: Live since May 14, 2026. Staking and fees on-chain. Secured by the live validator set (149 active of 156 total as of September 23, 2026).
• Public testnet history: 2 million+ wallets, 10 million+ transactions, 1.1 million+ smart contracts.
• Audits: Halborn (testnet and validator node platform), CertiK (Mainnet and smart contracts), Adevar Labs (Base to Autheo Mainnet bridge).
• THEO markets: Four verified venues — MEXC, Hydrex on Base, and two Uniswap pools on Robinhood Chain — with Enflux as liquidity partner across DEX and CEX.
• Token: THEO, native utility coin. Maximum supply 7.0 billion. Approximately 5.33% designated as initial circulating supply at the August 20, 2026 TGE ($0.05 reference price on Hydrex).
• 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. THEO is already trading; this is an allocation in a live utility token, not a promise against a future TGE. 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 and salaries. Salaried compensation is expected to begin within 4 to 5 months, following our node, token sales, or funding.

ROLE: Senior DeFi Engineer — Autheo | Live Mainnet, Staking, Pools & THEO Utility Job code: LA384

About The Role

Autheo is recruiting a Senior DeFi Engineer to ship the contracts that sit on a chain that is already live.

Mainnet has been up since May 14, 2026. Staking and fees settle on-chain. THEO trades on MEXC, Hydrex (Base), and Robinhood Chain. The job is the on-chain money path: staking and fee surfaces a user can finish, pools and vaults if a design is approved, oracle reads, and the accounting a reviewer can follow. Solidity on an EVM-compatible chain. Tests before a deploy.

VP of Exchanges owns the external venue book. The DEX GM owns Autheo’s own matching engine, if that venue is built. API & Interoperability owns the IBC packet and the bridge schema. You own the contract. You do not own a CEX integration, a wallet with a fiat ramp, or a governance token. THEO is not a governance token. Autheo is not a DAO.

Part-time does not mean advisory. Equity cofounder means you write the contract, you write the test, and you sit the review.

Key Responsibilities

• Contracts on Mainnet
• Staking, fee, and THEO utility flows a user can complete. Extend what is live. Do not fork a tutorial and call it a product.
• Pools, vaults, or a routing contract only against a written design. Invariants named: share price, fee, and who can move the funds.
• Token accounting you can explain to Security. Supply, emissions, and a pause. No hidden mint.
• Cross-chain only where the bridge already exists
• Assets that already move: Autheo native, and the Base path Adevar reviewed. A new route needs Protocol and API & Interoperability before you code it.
• Oracle or price reads with a stale-price check and a failure mode. Name the feed.
• Safety
• Foundry or Hardhat, fuzz or invariant tests on the paths that move value.
• An audit scope written before the audit, not after. You do not “conduct the audit” yourself and call it done.
• Post-quantum work stays on the platform roadmap (Kyber, Dilithium, Falcon). You do not bolt a PQC scheme onto a pool unless Security has a spec.
• Developer surface
• A short SDK or ABI notes in TypeScript so DevHub can call what you shipped. Python only if a partner is already on it.
• A simulation or a fork test a reviewer can run. Five minutes is a goal, not a slogan.

Qualifications

Required

• 5+ years shipping smart contracts that held value. A mainnet address, not a hackathon repo alone.
• Solidity in production. EVM traces you can read. Gas and storage you have measured.
• An AMM, a staking contract, a vault, or a bridge-adjacent pool you can walk through, including the bug you fixed or the one an auditor found.
• Tests you wrote: unit, fork, and at least one invariant or fuzz suite.
• Bachelor’s or Master’s in Computer Science, or equivalent practical depth.

Preferred

• Cosmos SDK or IBC enough to know when a transfer is a packet, not a function call.
• An audit you sat through, with the findings list.
• A public contract still in use.

Not persuasive on its own

• A claim of 50 billion TPS, a hybrid Binance aggregator, or a fiat-card wallet in 90 days. Bring the contract, the test, or neither.
• Polkadot JAM, Hyperledger, or Unity. Not this seat.

First 90 Days

• A written map of the DeFi surface that is live versus stubbed, agreed with Protocol and Security.
• One contract path taken from branch to a reviewed deploy on a public test path or Mainnet: staking, fee, or a pool with the invariant tested.
• Fork tests in CI, and an audit scope if the path moves value.
• ABI notes DevHub can call without you on the line.
• A one-page accounting note: supply, fees, and who can pause.

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. Mainnet is live. THEO is trading. DeFi engineering is the contract a user finishes on that network.

🌐 🚀 WHY JOIN LAUNCH LEGENDS?
