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—8+ 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.
