Sr. Software Dev Engineer, AWS OpenSearch Service

Imagine running search and analytics at any scale without thinking about clusters capacity or version upgrades. Where your queries return in milliseconds whether youre indexing a thousand documents or a hundred billion. Where the platform scales heals and secures itself so your team can focus on the questions not the infrastructure.

Thats what we build at Amazon OpenSearch Service.

Amazon OpenSearch Service is the fully managed and Serverless AWS service that lets customers deploy operate and scale OpenSearch for log analytics full-text search application monitoring observability and AI-powered retrieval. We serve hundreds of thousands of customers running mission-critical workloads across every AWS region and we are part of the AWS Database and Analytics organization.

Come join the OpenSearch Control Plane team. We are responsible for a service that:

- Reliably manages a large fleet of cloud-native OpenSearch clusters and collections freeing customers from sizing scaling and patching decisions
- Guarantees high availability and durability for mission-critical search and observability workloads at the scale of the most demanding internet businesses
- Orchestrates and automates the complete lifecycle of an OpenSearch cluster or collection from creation through scale-up scale-out upgrade replication and fail-over

The OpenSearch control plane is not just any distributed system. It orchestrates a fleet of clusters across every AWS region detects and recovers from node failures in seconds and serves workloads that span petabytes of customer data. Most recently we launched **OpenSearch Serverless NextGen** delivering ultra-fast collection provisioning and true scale-to-zero capacity so customers pay only for what they use and get a working environment in seconds rather than minutes. We are not done; this is one of many investments raising the bar for what customers can expect from a managed search service.

OpenSearch itself is a community-driven Apache 2.0licensed open-source search and analytics suite built on Apache Lucene. Since launching in July 2021 the project has delivered multiple major and minor releases advancing core search vector search and analytics. Our next phase focuses on transforming OpenSearch into an intelligent retrieval engine one that meets the evolving needs of customers running search analytics and AI-powered workloads across structured unstructured and multi-modal data.

We work in Java Rust Python and Go. We contribute upstream to OpenSearch and Apache Lucene. We are customer-obsessed operate with the entrepreneurial pace of a startup inside one of the worlds largest cloud providers and value strong intuition backed by metrics.

**Operations is core engineering on this team not overhead.** Engineers operate what they build and we treat customer-impacting incidents with the same engineering rigor we apply to feature work. Reliability and Static Stability is a forcing function for design not a phase after launch.
