About Perle
Perle delivers high-accuracy training and evaluation data for AI teams. We replace generic labeling vendors with expert-in-the-loop pipelines that are faster, more precise, and built for high-stakes use cases.
To expand on this vision, Perle is launching a new division called Perle Labs, a crypto-native ecosystem designed to transform how human input powers AI.
Perle Labs empowers teams to scale, verify, and reward high-quality human input for AI training and evaluation.
The Opportunity
Born from AI veterans from Scale, Amazon, Meta, MIT, and beyond, Perle Labs is looking for a versatile Blockchain Full Stack Engineer who thrives at the intersection of blockchain and AI. You’ll be building the platform layer of a next-generation AI data platform, one that integrates smart contracts, user wallets, etc.
What you'll do
- Architect and implement smart account systems (e.g. ERC-4337, ERC-7579, Solana equivalents) to streamline contributor onboarding, rewards, and interaction with AI workflows
- Build cross-chain infrastructure for wallet-based contributor identities and unified user experiences across EVM and SVM ecosystems
- Integrate on-chain payments and royalties systems for contributors and data originators
- Work closely with our AI/ML team to turn model feedback, incentives, and user behavior into intelligent, one-click actions
- Implement secure permissioning systems to manage data access, wallet actions, and role-based controls
- Optimize systems for latency, cost-efficiency, and transparency,especially when syncing on-chain and off-chain operations
- Move fast. You’ll ship features quickly based on live user feedback and ecosystem opportunities.
Qualifications
- 5+ years of experience shipping full-stack products (Node.js, TypeScript, React/Next.js)
- Strong experience building and deploying smart contracts on Solana (Rust)
- Solid understanding of DeFi or crypto incentive models
- Familiarity with API design, microservices, and real-time data infrastructure (e.g. WebSockets, GraphQL)
- Strong ownership mentality and product sense, you ship super fast and care about UX
Nice-to-have
- Experience with smart account standards: ERC-4337, 7579, 7702
- Experience building wallet tooling, bridges, or multi-chain infrastructure
- Familiarity with reinforcement learning or human-in-the-loop (HITL) systems
- Open source contributions in AI, blockchain, or data infrastructure
- Experience with incentive design or crypto-based gamification systems
What does a React developer in web3 do?
A React developer in the context of web3 is a developer who is using the React JavaScript library to build user interfaces for decentralized applications (dApps) that run on the Ethereum blockchain
These dApps often use smart contracts to facilitate transactions and other interactions on the Ethereum network
Overall, the role of a React developer in web3 involves using your skills in React development to help build cutting-edge decentralized applications that leverage the power of the Ethereum blockchain
As a React developer in web3, some of your responsibilities might include:
- Integrating the dApp with the Ethereum blockchain. This might involve using tools like web3.js and Ethers.js to connect to the Ethereum network and interact with smart contracts.
- Building the user interface for a dApp using React. This could involve creating components for the various elements of the dApp, such as buttons, forms, and other input elements.
- Implementing features that are specific to decentralized applications, such as handling cryptocurrency transactions and displaying data from the blockchain in a user-friendly way.
- Collaborating with other members of the development team, such as blockchain engineers and designers, to ensure that the dApp functions properly and meets the needs of the end users.
