Job Description:

Title: Crypto/Blockchain Architect

Location: Toronto, ON or NJ/NYC (4 days HYBRID)

Duration: Long term assignment

Job Description:

Position Overview

We are seeking a highly experienced Full Stack Architect specializing in digital assets and tokenization to lead enterprise architecture, solution strategy, and governance for blockchain-enabled platforms.
In this strategic role, you will bridge traditional financial infrastructure and decentralized systems by defining target-state architectures for tokenization platforms supporting real-world assets, digital securities, utility tokens, and institutional custody workflows.
You will provide architectural direction across backend services, decentralized application experiences, smart contract ecosystems, public EVM and Layer 2 networks, enterprise permissioned chains, and managed Blockchain-as-a-Service platforms.

Key Responsibilities

Architecture and Platform Design
Define scalable, end-to-end tokenization architectures that align user experiences, middleware services, indexers, custody capabilities, and smart contract ecosystems.
Provide solution direction for enterprise-grade blockchain nodes and Blockchain-as-a-Service environments, including Hyperledger Besu, Quorum, Corda, Kaleido, and Blockdaemon, to support compliant, privacy-preserving network topologies.
Own critical architectural decisions by authoring and championing Architectural Decision Records, driving stakeholder reviews, and guiding decisions through formal architecture governance channels.
Design, communicate, and socialize end-to-end target-state architectures, solution blueprints, and strategic technology roadmaps.
Create consensus across cross-functional leadership and engineering teams, proactively navigating competing priorities to resolve complex or controversial technical decisions.
Elevate team capability by mentoring developers and architects, fostering continuous technical growth, and supporting succession planning.
Partner with engineering leaders throughout the delivery lifecycle to ensure implementations remain aligned with approved target-state architectures.
Tokenization and Smart Contract Engineering
Set architectural direction for tokenized real-world assets, debt, equities, funds, and stablecoins using standards such as ERC-20, ERC-721, ERC-1155, ERC-3643/T-REX, and ERC-1400.
Define governance expectations for smart contract testing, formal verification, and upgradeability patterns, including ERC-2535 Diamond Standard and proxy contracts.
Oversee protocol security audit strategy with third-party security firms and ensure remediation plans are incorporated into release governance.
Full Stack Technical Leadership
Define architectural standards for React and Next.js frontends that interact with Web3 libraries such as Ethers.js, Viem, and Wagmi.
Guide architectural patterns for scalable backend services in Node.js, Go, or Rust, with emphasis on reliability, maintainability, and production readiness.
Custody, Key Management, and Institutional UX
Shape enterprise integration strategy for MPC wallet infrastructure providers such as DFNS, Fireblocks, BitGo, Turnkey, and Anchorage, as well as Hardware Security Modules for transaction signing and treasury management.
Define user experience architecture for account abstraction, including ERC-4337, social logins, and gasless transaction relayers such as Biconomy and Gelato, to support seamless institutional onboarding.
Regulatory and Compliance Technology
Establish architectural requirements for on-chain and off-chain identity management, including KYC/AML accreditation rules, transfer restriction engines, and transaction monitoring tools such as Chainalysis and Elliptic.
Ensure solution designs support regulatory compliance, auditability, and operational controls across tokenized asset workflows.

Required Experience

Experience leading architecture for production-grade Web3 or digital asset applications.
Proven track record guiding live tokenization platforms, real-world asset solutions, or institutional crypto custody systems from concept through production governance.
Strong architectural understanding of enterprise EVM nodes, such as Hyperledger Besu, and blockchain infrastructure platforms such as Kaleido or Blockdaemon.
Experience defining integration approaches for programmatic MPC wallet infrastructure, e.g. DFNS, Fireblocks, or Turnkey.
Deep understanding of smart contract security risks, audit governance, and gas optimization tradeoffs.

Preferred Qualifications

Hands-on experience with Zero-Knowledge proofs, including zk-SNARKs and zk-STARKs, for privacy-preserving asset transactions.
Hands-on experience deploying a tokenization solution for real-world assets, digital securities, funds, stablecoins, or institutional digital asset workflows.
Familiarity with institutional settlement systems, including FIX protocol, Swift, and ISO 20022 messaging.
Hands-on open-source contributions to major Web3 frameworks, Ethereum Improvement Proposals, or tokenization standards.
Certifications in AWS or GCP cloud architecture, blockchain security, or related disciplines.
