Kestra Technologies - Senior Backend Engineer, AI Orchestration
Requirements
• 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 • 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
Benefits
• Work from anywhere: We’re a remote-first company, so you can work from wherever feels like home. Plus, you’ll have access to coworking spaces worldwide if you ever need a change of scenery. • Health coverage: From medical support, dental, and vision, we've got you covered. • Home office setup on us: We’ll provide all the equipment you need to work comfortably. • OUR HIRING PROCESS • We aim to move quickly (2-3 weeks), but we can adjust the timeline if needed. • Intro call with the hiring manager (30 min) • Technical test (2 hour, homework done in async) • Team chat with two of your future colleagues (30 min) • Final discussion with one of our co-founders (30 min) • We’re here to make the process smooth and transparent for you. • This is a Java-first role. The AI ecosystem is mostly Python and we know that. We can work with someone who has built AI systems in Python (or in TypeScript via LangChain.js) and has a solid Java background to grow from. We cannot work with someone who only knows the Python AI stack and does not want to write Java. • We are also not looking for candidates whose AI experience is a single demo or a personal side project. We want people who have run AI in production, dealt with outages, and learned from the failures that come with it.
