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.
