Additional Information

Come build the future of data streaming with the Amazon Managed Streaming for Apache Kafka (MSK) team. We're looking for builders who want to work on one of the fastest-growing services in AWS. Amazon MSK is a fully managed Apache Kafka service, and if you care about data streaming, open source, and operating at scale, this is the team. You'll work across the full stack: the control plane APIs, the Kafka platform itself, and the tooling that makes Kafka easier to run for everyone. Upstream compatibility is a core tenet. Your changes to Kafka ship back to open source. That's the deal, and it's a good one. You get to build inside AWS and contribute to one of the most widely adopted open-source platforms in the world. Day to day, you'll design features, improve performance, prototype solutions, and ship code that serves customers directly. You'll collaborate with engineers across the team and work with senior leaders to shape the roadmap, including identifying what needs to change in the upstream platform to unlock what customers need next. We're looking for people who've built large-scale distributed systems, who enjoy hard problems, and who can reason about tradeoffs at the intersection of performance, reliability, and cost. Experience with Kafka, Kinesis, Flink, or Spark is a plus. What matters more is that you're curious, you ship, and you think in systems.
