Full-stack Blockchain Developer (ai-native)

Infra Singularity 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, Eigen Layer, and Avail .

We are looking for a versatile Full-Stack Blockchain Engineer who can bridge the gap between traditional EVM-based d Apps and sophisticated, privacy-preserving Daml workflows. What you'll be doing: Architect & Build: Develop scalable full-stack Web3 applications using React, Next.js, and Nest JS with Type Script. Basic awareness of AI concepts and tools , including a high-level understanding of RAG (Retrieval-Augmented Generation) , vector databases , and frameworks like Lang Chain; 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 Nest JS that interface with the Daml Ledger API (via g RPC or JSON API) and standard blockchain providers.

DApp Experience: Lead frontend development for decentralized applications, ensuring smooth wallet integrations (Meta Mask, Wallet Connect) 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 Nest JS (Type Script).

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 Type Script/Java Script 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 .
