• Ability to work in fast-paced startup environments.

Responsibilities

• Design and implement smart contract architecture for NFT-based property ownership, transfers, and fractionalization.
• Build and maintain contracts using Solidity (Hardhat), ensuring security, upgradeability, and gas efficiency.
• Integrate blockchain functionality with backend services and frontend apps.
• Define and manage on-chain/off-chain data interactions (IPFS, metadata, ownership records).
• Support multi-chain strategy (Ethereum / Polygon) and evaluate L2 scaling solutions.
• Collaborate with product and legal teams on tokenization models and compliance.
• Prepare code for audits and implement security best practices.
• Contribute to wallet integration and Web3 authentication flows.

Job description

TokenBrickLabs is a Seattle-based blockchain studio that designs, audits, and ships production Real-World Asset tokenization — issuance, identity, custody, and settlement rails for funds, fintechs, and operators. We hire globally and build for institutional security, compliance, and day-two operations, not slide-deck prototypes.

As a Blockchain Architect, you will own the on-chain architecture of that stack: contract boundaries, upgrade paths, multi-chain strategy, and the security model that issuance and custody products depend on. The role is open as full-time or part-time.

Reports to

At TokenBrickLabs, we are engineering the institutional standard for Real-World Asset tokenization. Our mission is to ship platforms centered on security and compliance, requiring a commitment to technical excellence that extends beyond simply delivering code. As a global organization, we set a high bar for those driven to do their best work alongside world-class peers.We value engineers who treat development as a craft and own the outcome from concept to deployment. We expect our teams to bring structure to ambiguity and shape the frameworks that support our studio. We refuse to compromise on quality and seek problem solvers who thrive on high-impact technical challenges.

The Team: Protocol Architecture

Protocol Architecture sets the contract and systems design for TokenBrickLabs issuances. We define token standards, identity hooks, upgradeability, and how protocol work lands in backend and operator products. The bar is production: audit-ready, gas-aware, and operable in regulated jurisdictions.

What you’ll do

• Design and implement smart contract architecture for NFT-based property ownership, transfers, and fractionalization.
• Build and maintain contracts using Solidity (Hardhat), ensuring security, upgradeability, and gas efficiency.
• Integrate blockchain functionality with backend services and frontend apps.
• Define and manage on-chain/off-chain data interactions (IPFS, metadata, ownership records).
• Support multi-chain strategy (Ethereum / Polygon) and evaluate L2 scaling solutions.
• Collaborate with product and legal teams on tokenization models and compliance.
• Prepare code for audits and implement security best practices.
• Contribute to wallet integration and Web3 authentication flows.

Nice to have

• Experience designing upgradeable, permissioned, or RWA token systems.
• Prior work preparing protocols for external security audits.
• Familiarity with L2s, account abstraction, or institutional custody models.
• Opportunity to work at the bleeding edge of Web3 / crypto / DeFi.
• Flexible working conditions.
• Offer token/equity packages.
• Sponsored global events and travel.
• Annual global 2-week offsite.
