Senior Software Development Engineer, Distributed SQL

The Distributed SQL team at AWS is building revolutionary transactional database technology, delivering innovative customer experiences in the areas of automated operations, global scale, query processing, and storage. If contributing to the design and development of a new, first-of-its-kind, database excites you, then a role on this new initiative may be your dream job. Join us during this formative period of the product and be a leader in shaping the future of databases at Amazon and beyond!

The Query Processing sub-team (QP) owns everything in the life cycle of a SQL statement like Parsing, Analysis (syntax and semantic), Rewriting, Planning (Optimizer) and Execution, and working with custom built Storage while providing customers access to observability metrics to help them understand their database performance better. As an Engineer on this team, you will be responsible for building a highly distributed and performant database system with a focus on query processing. This will involve designing and implementing key query processing components such as the query optimizer, planner, and execution engine. You will work on optimizing queries through techniques like heuristic-based rewrites, cost-based optimizations, improved cardinality estimations, and leveraging runtime feedback to enhance the query optimization process. You will be identifying and resolving performance bottlenecks in the overall query processing system to ensure efficient and scalable database operations.

An ideal candidate has experience building databases and/or large stateful cloud services, is able to dive into complex problems, and is able to invent simple and elegant solutions for the same. They are able to design, implement and deliver cutting edge software systems and mentor junior team members. They thrive on creative and collaborative problem solving, and also enjoy the challenge of operating services at AWS scale.

AWS Utility Computing (UC) provides product innovations - from foundational services such as Amazon's Simple Storage Service (S3) and Amazon Elastic Compute Cloud (EC2), to consistently released new product innovations that continue to set AWS's services and features apart in the industry. As a member of the UC organization, you'll support the development and management of Compute, Database, Storage, Internet of Things (Iot), Platform, and Productivity Apps services in AWS, including support for customers who require specialized security solutions for their cloud services
