Job description

Job Summary

The Blockchain Architect will serve as a senior technical leader within the Architecture group, combining deep domain expertise in blockchain and Web3 with strategic thinking. This role will define, guide, and evolve enterprise and platform architectures, designing scalable, secure, and resilient blockchain-enabled solutions across complex, multi‑system environments, while ensuring alignment with regulated, enterprise‑grade design principles and operational rigor appropriate for a large financial institution. The Architect will translate business strategy into technical direction, lead cross‑functional alignment, mentor other architects and engineers, and drive long‑term architectural consistency and innovation.

Key Responsibilities

• Provide architectural leadership for blockchain‑enabled initiatives, including tokenized deposits, digital assets, and distributed settlement use cases, ensuring solutions align with bank‑grade security, resiliency, and regulatory expectations.
• Design hybrid architectures that integrate distributed ledger platforms with core banking systems, payment platforms, data stores, and event‑driven microservices.
• Define appropriate on‑chain vs off‑chain responsibilities, including smart contracts, orchestration services, API layers, and operational controls.
• Evaluate and guide usage of permissioned distributed ledger technologies, identity and access models, privacy architectures, and governance structures suitable for regulated environments.
• Establish architectural guardrails and best practices for emerging digital asset and blockchain capabilities, avoiding vendor lock‑in and ensuring long‑term interoperability and maintainability.
• Provide thought leadership to engineering teams and stakeholders on where blockchain adds business value versus where traditional platforms remain more appropriate.

Required Qualifications

• 10+ years of experience demonstrating mastery of architectural patterns, cloud and modern engineering practices, and non‑functional requirements such as performance, resiliency, and security.
• Familiarity with smart contract concepts as deterministic business rule enforcement, not as workflow orchestration.
• Experience working across payments, liquidity, settlements, or financial market infrastructures in large‑scale enterprises.
