Elastic, the Search AI Company, enables everyone to find the answers they need in real time, using all their data, at scale — unleashing the potential of businesses and people. By taking advantage of all structured and unstructured data — securing and protecting private information more effectively — Elastic's complete, cloud-based solutions for search, security, and observability help organizations deliver on the promise of AI. We are on the lookout for a Senior Java Developer to join our Elasticsearch team and drive our work on the Inference API in Elasticsearch. The Elasticsearch Inference API is the integration layer between Elasticsearch and external machine learning services including Elastic's own Elastic Inference Service (EIS), third-party providers (Anthropic, OpenAI, Cohere, Google), and self-hosted models. It powers features like semantic search, reranking, and generative AI across Elastic Cloud and in hosted environments. You'll maintain and develop the plugin framework and REST API with your work spanning protocol design, streaming, async execution, billing integration, and with a tight collaboration with the wider inference team and the Kibana team. Contribute to the inference plugin's internal architecture: task settings, chunking strategies, rate limiting, and provider-level configuration Write thorough tests: unit tests using ESTestCase, YAML-based REST integration tests, and rolling-upgrade tests 5+ years of production Java experience, with experience contributing to a large, established Java codebase. You know core Java and are conversant in the standard library of data structures and concurrency constructs, as well as newer language features. ~ Experience with low-level Java such as concurrency, parallelism, classloaders, etc.
