What is The Role

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.

What You Will Be Doing

• Build and maintain integrations with internal systems and external inference providers, including schema negotiation, streaming (SSE), and error normalisation

• Contribute to the inference plugin's internal architecture: task settings, chunking strategies, rate limiting, and provider-level configuration

• Review open source contributions to the codebase and work with third party engineers to ensure their contributions meet our technology standards

• Participate in on-call rotation for inference-related incidents

• Write thorough tests: unit tests using ESTestC
