Jaka Lounge is supporting our client — a stealth Web3 startup building the next generation of investment infrastructure through full-stack legal entity tokenisation. Their goal is to bring trillions of dollars on-chain, starting with regulated fund structures.

As a licensed EU financial institution, they are creating an on-chain operating system that is programmable, interoperable, and fully compliant across the EU, UK, and US. Backed by experienced founders and investors from fintech, crypto, and media, the company is on a mission to reshape how capital is created, flows, and grows — bridging the gap between traditional finance and Web3.

The Role

We are looking for a Founding Blockchain Engineer to own the smart contract stack and core architecture of this platform. You’ll work directly with the founding team to design and build the on-chain protocol for tokenised investment products — including fund issuance, redemptions, compliance logic, and capital flow infrastructure.

This is a deeply technical role with high impact and long-term ownership. You will be the most senior blockchain engineer in the team, shaping how the product is built — not the title or hierarchy.

Key Responsibilities

  • Design and implement Solidity smart contracts (EVM)
  • Architect scalable backend logic for fund units, subscriptions/redemptions, and NAV-based flows
  • Lead infrastructure decisions: blockchain network selection, token standards (e.g. ERC-4626), DevOps pipelines, and audit readiness
  • Work closely with legal and product teams to ensure full regulatory compliance (e.g. transfer restrictions, account recovery)
  • Contribute to hiring and early engineering culture

Must-haves:

  • 4+ years of experience building production-grade Solidity contracts
  • Proven ability to architect and scale Web3 systems
  • Deep familiarity with Ethereum tooling: Foundry / Hardhat, The Graph, Gnosis Safe, etc.
  • Understanding of security, gas optimization, and audit best practices
  • Comfortable working in a fast-moving, ambiguous startup environment

Nice-to-haves:

  • Familiarity with DeFi, staking/yield protocols, or fund governance
  • Experience with ERC-4626, ERC-1400, or ERC-3643 standards
  • Knowledge of Layer 2s, Avalanche subnets, or private blockchain deployments
  • Exposure to fund administration, NAV processes, or fintech infrastructure

Why Join

  • Build with builders: work directly with the founding team, no managers or overhead
  • Early equity and long-term ownership in a company aiming to build for 100 years
  • High-impact work that merges crypto-native technology with real-world financial use cases
  • Help define a new category of compliant DeFi infrastructure
