Head of Trading Systems Matching â Autheo Spot & Perpetual Venue | Order Book, Latency & Settlement

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
• THEO token launch & verified markets 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.

  Autheo Mainnet has been live since May 14 2026. 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. The venue you will build is not.

  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. MEXC serves more than 40 million users across more than 170 countries and regions. 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 pairing THEO with a Robinhood Stock Token. Official Robinhood Chain contract: 0x3dc751e0da01812e6d9143cc696e7f07ea94da48

  Verified trading links contract addresses and network information: are external markets. This seat does not run them.

  Key Features

  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 and salaries. Salaried compensation is expected to begin within 4 to 5 months following our node token sales or funding.

  ROLE: Head of Trading Systems / Matching Autheo Spot & Perpetual Venue Order Book Latency & Settlement

  About the Role

  Autheo is recruiting the person who will build the matcher.

  THEO already trades on MEXC Hydrex and Uniswap on Robinhood Chain. That book is not yours. A separate seat VP of Exchanges & Token Markets owns those external listings and the next ones. A second seat Head of Markets / DEX GM owns the venue as a product and a P&L: listing policy fees maker program insurance fund and the architecture decision. You report into that GM. You do not replace them.

  You design and ship the trading system: central limit order book matching cancel/replace self-trade prevention time-in-force funding ticks the liquidation handoff and the path from a matched trade to settlement on Autheo. The comparable engines are Hyperliquids on-chain book Lighters zk-proven matcher and dYdX v4s validator-run matching. The underlyings are not only crypto. V1 has to carry THEO spot two to three crypto perps one infrastructure future one RWA and one agent-credit or agent-SLA market. If the engine can only price BTC it is the wrong engine.

  The GM picks the architecture in week one. The rational first choices are validator-run matching on Autheos Cosmos stack or an off-chain matcher with proofs settling on the Autheo EVM. A native CLOB is on the table only if you can carry it. Deploying markets on someone elses engine is a go-to-market tactic not this job.

  This is a systems seat. Rust or Go. Not a Solidity role with a matching diagram attached.

  Key Responsibilities

  • Build the matching engine: price-time priority or the priority model the GM signs with deterministic behavior under cancel races
  • Specify and ship order types for v1: limit market post-only IOC GTC and the cancel/replace path a market maker will actually use
  • Set the latency budget and measure it. Median p99 and what happens when the book is under load. A number you cannot reproduce is not a number
  • Implement self-trade prevention sequence numbers and a fairness rule you can explain to a market maker in one page
  • Own the funding tick mark-price input and the handoff into liquidation. You do not own margin math or the insurance fund. Head of Risk Clearing & Oracles owns those. You own the engine that calls them on time
  • Settle matched trades on Autheo: native module Cosmos sidecar or proof plus EVM settlement per the architecture decision. IBC and the EVM environment are already there. Do not invent a second chain to avoid them
  • Design the state model so an infrastructure future an RWA perp and an agent-credit market can list without a rewrite. Oracle inputs are the risk seats problem. Consuming them without stalling the book is yours
  • Publish a failure spec: sequencer stall proof lag validator halt clock skew duplicate cancel crossed book. Each one gets a behavior not a hope
  • Instrument the book: order-ack time cancel-ack time match rate reject reasons and a replay log that can reconstruct a session
  • Hire or designate the first two engineers under this seat only after the spec is written. A team without a matching spec is a club

  Requirements Must Have

  • Has shipped a live matching engine or the core of one on a venue with real orders. A backtest and a whitepaper do not count
  • Can defend price-time priority cancel/replace self-trade prevention and sequence gaps on a whiteboard without notes
  • Writes the hot path in Rust or Go. Solidity is acceptable for settlement not for matching
  • Has operated a latency budget under load and can show the measurement not the target
  • Understands how a perp funding tick and a liquidation handoff sit next to the matcher even if someone else owns the risk formula
  • Will take an architecture decision from the GM validator-run zk-proven off-chain or native CLOB and implement it rather than reopen it every week

  Nice to Have

  • Time on a Hyperliquid Lighter dYdX Injective Sei or Osmosis trading system or on a Jump Wintermute HRT or Citadel crypto execution stack
  • Cosmos SDK module experience CometBFT or a zk proof pipeline used for matching or state commitments
  • Built a replay and deterministic-simulation harness for an order book
  • Familiarity with non-crypto underlyings enough to keep oracle reads off the match path
  • Post-quantum signature verification costs if TheoID key material ever sits on the order path. It should not sit on the hot path in v1

  First 90-Day Deliverables

  • Matching spec: priority order types cancel/replace self-trade prevention sequence numbers and the reject table
  • Latency budget with a measurement method and a first number from a test harness not a slide
  • Settlement design against the chosen architecture written to Autheo L1 not to a generic chain
  • Failure spec covering stall proof lag duplicate cancel and crossed book
  • Replay log format sufficient to reconstruct one session trade for trade
  • A working testnet matcher on THEO spot and one perp with the liquidation handoff stubbed to the risk seats interface

  About Our Organization

  Autheo is building the Internet operating system: a decentralized coordination layer for the Web blockchain and AI agents. The platform uses W3C Decentralized Identifiers as its native identity framework and is anchored by a post-quantum communications and identity roadmap on NIST-standardized cryptography. Operating alongside a sovereign Cosmos-based Layer-0 and an EVM-compatible Layer-1 Autheo is designed so applications infrastructure and agents settle in one system rather than five vendor stacks.

  The economic layer is already open. THEO trades on MEXC on Hydrex on Base and on Uniswap on Robinhood Chain. The next market is the one Autheo matches itself.

  WHY JOIN LAUNCH LEGENDS

  • The coin is already listed. MEXC opened October 1 2026. Hydrex and Robinhood Chain were already live. You are not building a matcher for a token that has never traded.
  • The engine does not exist yet. External venues are someone elses book. This seat is the book Autheo will run.
  • A GM above you a risk seat beside you. You will not be asked to set fees recruit market makers and design the insurance fund in the same week. You will be asked to make the match deterministic.
  • Equity cofounder not a contractor seat. You join the same model as the rest of the collective: equity in Launch Legends Autheo and the WFO Creator Network plus THEO allocation with salary expected to follow node token or funding milestones.

  If you have shipped a matcher can say what a cancel does under load and would rather write the engine than the listing announcement we invite you to take the next step.

  Lets build the bookon the network that is already live.
