Position: Contract

Location: San Leandro, CA

Duration: 12+ months

Job description:

🔹 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.

🔹 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.

🔹 Establish architectural guardrails and best practices for emerging digital asset and blockchain

capabilities, avoiding vendor lock-in and ensuring long-term interoperability and maintainability.
