Software Dev Engineer II, AWS Transactional Services (Database & Distributed Systems)

Ever wonder what happens when S3 processes a PUT request when EC2 launches a new instance when DynamoDB commits a write with single-digit millisecond latency or when Kinesis Data Streams ingests a new record Behind the scenes a distributed log service is making it all possible and youd be building it.

The Transactional Services organization builds foundational distributed systems that power the largest AWS services. We specialize in high-performance strongly consistent data systems that operate at scale. Our systems process over 4 million writes per second today and are growing fast. When we ship the blast radius is AWS itself.

We have a multi-year roadmap packed with hard unsolved problems: building next-generation data export services driving large-scale migrations that will reshape Amazons storage infrastructure and pushing the boundaries of durability availability and performance in distributed log systems. This isnt incremental work its foundational.

Youll work alongside multiple Senior and Principal Engineers on a tight-knit team of 12 that values pairing co-ownership and direct collaboration.
