Are you interested in building hyper-scale database services? Do you want to revolutionize the way distributed systems are built for the cloud? Do you want to have direct and immediate impact on hundreds of thousands of users who use AWS database services?Quantum Ledger Database(QLDB) is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log of all application data changes over time. It offers SQL-like APIs, a flexible document data model and full support for transactions. QLDB eliminates the need for organizations to build ledger-like functionality when their applications require audit-ability and verifiability, such as, when tracking the history of credits and debits in banking applications, verifying data lineage of an insurance claim, or tracing movement of an item in a supply chain network. QLDB is serverless and highly scalable, allowing customers to scale effortlessly to support the demands of their applications.Key job responsibilitiesIn this role, you will build and operate the mission critical distributed systems that power QLDB.
