Blockchain Engineer

About the Role You will design and implement secure, auditable on chain smart contract logic for tokenization asset management and governance. You will work with a queue based architecture to create transactions send them to the blockchain node and manage the responses to keep the ledger in sync. You will integrate blockchain and distributed ledger technologies into backend systems. You will evaluate test and deploy blockchain logic on networks such as Cosmos Liquid and other Layer 1s. You will build tools for interacting with on chain infrastructure including transaction monitoring and wallet integrations. You will collaborate with product and engineering teams to deliver robust blockchain based solutions for financial institutions. You will stay up to date on developments in blockchain infrastructure standards and regulatory frameworks. You will promote best practices in blockchain security and operational resilience.
