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
