Shape the Future of Blockchain—Bringing Business On-Chain

We are offering a unique opportunity to join Launch Legends as a part-time equity co-founder. Founded nearly four years ago, Launch Legends is pioneering the merging of Web3 blockchain technology with the next major wave of Web2 integration, bringing businesses on-chain with sophisticated Enterprise, DePIN, and DeFi organizations and projects.

This role places you at the heart of innovation, driving the development of Autheo, our cutting-edge blockchain ecosystem, which extends beyond a Layer-1 blockchain to include decentralized compute, storage, identity, and service marketplaces. Autheo is designed for enterprise adoption, Web3 integration, and scalable decentralized solutions, enabling businesses and developers to seamlessly transition into the next generation of the digital economy.

Our Projects:

  • Launch Legends: www.launchlegends.io
  • WFO (being built on Autheo): www.instagram.com/gowfotv

About Autheo

With nearly 100 equity cofounders working on the project, Autheo is pioneering a new era of blockchain adoption, solving the key challenges preventing businesses from integrating blockchain technology. Our infrastructure-first approach ensures seamless Web2-to-Web3 migration without requiring deep crypto expertise.

  • Enterprise-Grade Blockchain Infrastructure – A next-gen Layer-1 blockchain providing self-securing, high-speed, and cost-efficient Web3 solutions.
  • Developer Hub & Application Marketplace – A decentralized platform where developers build, deploy, and monetize real-world applications.
  • Universal Web2-Web3 Integration – Seamlessly migrating businesses on-chain with microservices, SDKs, and a structured governance model.
  • Decentralized Cloud & Compute Services – Powering secure, privacy-preserving storage, AI automation, and next-gen financial tools.
  • DePIN (Decentralized Physical Infrastructure Networks) – Enabling real-world physical infrastructure projects on-chain, fostering decentralized network ownership, and supporting innovative resource-sharing models.

Autheo is not a retail crypto project—it is an infrastructure-first blockchain designed for real adoption, allowing businesses to migrate on-chain without needing crypto expertise.

Current Roadmap:

  • Airdrop Launch: March 1, 2025
  • Node Sale: April 2025
  • Public Token Sale: May 2025
  • Decentralized Cloud Launch: May 2025
  • Decentralized ID Rollout: June 2025

Future Compensation Plans

Initially, this role is an equity cofounder role, where compensation is initially equity and token allocations. We have completed an initial round of funding for infrastructure and marketing. Following the anticipated public token sale (anticipated in 90 to 120 days), or a successive round of funding, we plan to introduce salaries alongside equity and token rewards.

 

POSITION: SDK Framework Engineer – Blockchain & Fullstack Developer Tooling

Autheo is developing a fullstack Layer-1 platform that bridges Web2 and Web3 infrastructure through modular SDKs, decentralized identity systems, smart contract tooling, and cloud integration. We’re looking for a seasoned SDK Framework Engineer to lead the development of our SDK architecture, ensuring developers can easily interact with blockchain features, APIs, decentralized storage, and compute environments.

You’ll work across teams to deliver SDKs that power frontend applications, backend services, and developer tools. This role requires experience building developer platforms using TypeScript, React, Go, and smart contract protocols like Cosmos SDK or EVM. It’s ideal for someone passionate about Web3 infrastructure and enabling scalable dApp development.

RESPONSIBLITIES:

• SDK Development—Design and build JavaScript/TypeScript and Go SDKs that abstract blockchain logic, decentralized identity, and smart contract operations. Deliver clean, modular libraries for frontend and backend developers.

• Frontend & Mobile Integration—Work closely with teams using React, Next.js, and React Native to support seamless SDK usage across web and mobile dApps.

• Smart Contract & Blockchain Support—Integrate Cosmos SDK and CosmWasm modules, including staking, validator, and governance functionality, as well as EVM-compatible smart contract execution.

• Backend Services—Implement and maintain Golang microservices to support off-chain processes, data pipelines, and integration with compute and storage layers.

• Developer Tooling—Create local testing environments, simulation tools, CLI interfaces, and reusable templates to simplify the development experience within the Autheo DevHub.

• Identity & Decentralized Infrastructure—Support SDK interfaces for decentralized identity (DID), IPFS storage, and decentralized compute APIs.

• DevOps & CI/CD—Collaborate with DevOps to integrate SDK workflows with CI/CD pipelines, automated testing, and deployment tooling.

• Developer Engagement—Assist partners and internal teams with SDK adoption, documentation, and debugging. Participate in community initiatives, workshops, and hackathons.

QUALIFICATIONS:

• Fullstack Experience—4+ years of experience in fullstack or SDK development with demonstrated contributions to developer tooling, open-source projects, or platform engineering.

• Programming Proficiency—Advanced skills in JavaScript, TypeScript, and Golang. Strong experience with React, Next.js, and React Native frameworks.

• Blockchain & Web3—Hands-on experience with blockchain protocols including Cosmos SDK, CosmWasm, smart contracts (Rust/Solidity), or EVM-based tooling.

• Decentralized Technologies—Familiarity with IPFS, decentralized compute layers, DID frameworks, and smart contract systems.

• SDK Architecture—Experience designing modular SDKs, maintaining versioned libraries, and writing clear developer-facing APIs and wrappers.

• Collaboration & Communication—Excellent collaboration skills across product, DevOps, and engineering teams. Ability to support external developers and contribute to documentation.

• Bonus—Previous contributions to developer portals, SDKs for blockchain platforms, Web3 standsards, or developer community initiatives.

 

WHAT YOU WILL GAIN AS A COFOUNDER

As a part-time equity co-founder, you will:

  • Work with a global team of nearly 100 equity co-founders, bringing together deep expertise across blockchain, AI, and full-stack Web3 integration.
