Software Development Engineer

Amazon Quantum Ledger Database, a next generation purpose built database technology was announced in Preview at re:Invent 2018 and is seeing tremendous interest from AWS customers! It is a revolutionary OLTP database with highly scalable throughput. Join us during this formative period of the product and be a leader in shaping the future of Amazon QLDB.

Amazon 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 a SQL-like API, 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.

The Developer Experience team aspires to build highly scalable, high performant data plane APIs and developer tools like AWS Console, QLDB Workbench, QLDB Drivers that offer first-class developer experience. We are looking for engineers who are customer obsessed and who can learn and dive into distributed systems and database problems to invent simple and elegant solutions. In this role, you will care deeply about customer experience and focus on building performant systems that offer idiomatic interfaces to customers. You will collaborate with a team of highly skilled engineers to build mission critical distributed systems that power QLDB's data plane. You will have high standards for yourself and everyone you work with, you will drive engineering best practices and be constantly looking for ways to make the systems you own better. You have great communication skills and enjoy working in a fast-paced, collaborative team environment.

You will get to work in a variety of languages and with multiple frameworks to support our customers in the choices they make to integrate with QLDB.
