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 .
