Full-stack Blockchain Developer (AI Native)

InfraSingularity is a pioneering investor and builder within the Web3 ecosystem. Our mission is to spearhead infrastructure development for top-tier protocols including Lava, Sei, Anoma, EigenLayer, and Avail. We are looking for a versatile Full-Stack Blockchain Engineer who can bridge the gap between traditional EVM-based dApps and sophisticated, privacy-preserving Daml workflows. What you'll be doing: - Architect & Build: Develop scalable full-stack Web3 applications using React, Next.js, and NestJS with TypeScript. - Basic awareness of AI concepts and tools, including a high-level understanding of RAG (Retrieval-Augmented Generation), vector databases, and frameworks like LangChain; willingness to learn and work on AI-native features is a plus. - Daml Logic Design: Model complex multi-party agreements and distributed workflows using Daml, ensuring fine-grained authorization and data privacy. - Smart Contract Engineering: Develop and deploy secure contracts in Solidity while integrating them with Daml-driven ledger environments. - API & Integration: Build backend services with NestJS that interface with the Daml Ledger API (via gRPC or JSON API) and standard blockchain providers. - DApp Experience: Lead frontend development for decentralized applications, ensuring smooth wallet integrations (MetaMask, WalletConnect) and intuitive UX for complex financial interactions. - Security First: Implement best practices for privacy-preserving data modeling and secure transaction signing across both public and private ledgers. What we look for in you: - Core Stack: 3+ years of engineering experience with React, Next.js, and NestJS (TypeScript). - Daml Proficiency: Hands-on experience writing Daml templates, choices, and triggers. Deep understanding of the Daml Ledger model (Signatories, Observers, and Parties). - Web3 Libraries: Proven ability to use ethers.js, wagmi, and rainbowkit alongside Daml TypeScript/JavaScript libraries. - Functional Programming: Strong grasp of functional paradigms (Daml/Haskell/Scala) to write clean, predictable code. - Protocol Knowledge: Familiarity with Solidity (EVM) and an interest in emerging stacks like Rust (Anoma/Sei). - Autonomy: Ability to drive end-to-end features in a fast-paced, collaborative startup environment. Bonus Points for: - Enterprise Ledgers: Experience deploying Daml on Canton, Hyperledger Fabric, Besu, or Cordax.
