Senior Backend Engineer, AI Orchestration

Role Description

Kestra orchestrates workflows across systems and domains. AI agents and LLM-driven workflows are a growing part of that, and this role is about making sure they can run reliably inside the orchestrator. This is not a wrapper around a model API, but a platform orchestrating how agent steps should be run, retried, branched, and kept observable inside the orchestrator. That work happens in the Kestra core, which is Java.

• Design and build the execution primitives for AI workflows in the Kestra engine
• Build and maintain the plugins that connect Kestra to LLM providers and agent frameworks
• Turn real agent use cases into reusable blueprints, together with the product team
• Keep AI executions observable and debuggable to the same standard as the rest of Kestra

Qualifications

• A strong Java background. You have built and maintained production Java systems, not used Java in passing.
• Hands-on experience with LangChain4j or a comparable Java agent framework
• A clear mental model of how agentic systems are actually run: tool calls, state, retries, failure modes
• Comfort working close to an orchestration engine, where correctness and reliability matter more than demos

Requirements

• Backend: Java, Micronaut
• Frontend: Vue.js, Bootstrap
• Datastore: Kafka, Elasticsearch, PostgreSQL, MySQL
• Infrastructure: Docker, Kubernetes, Terraform
• Cloud: GCP, AWS, Azure
• Tools: GitHub for repo management, actions, and issues
