Product Engineer, AI

About Kestra

At Kestra, we’re on a mission to make orchestration and automation simpler for everyone. Our open-source platform helps teams manage complex workflows with confidence, and we’re already making a big impact in businesses around the world. Now, we’re looking for a Full Stack Engineer to help us take things to the next level.

In March 2026, we closed a $25M Series A led by RTP Global, with participation from Alven, ISAI, and Axeleo – backed by founders from Datadog, dbt Labs, and Hugging Face.

About the role

Kestra orchestrates workflows across systems and domains, and AI agents and LLM-driven workflows are a growing part of that. This is a builder role. We want someone who can take an AI use case and build it end to end, from the Kestra engine through to the UI, and get it in front of users fast. Prototype use cases and turn the best ones into features and blueprints.

If you are an unusually strong full-stack builder with real AI experience, we want to talk to you even if you do not fit a standard job box.

What you would do

• Build AI features end to end, backend and frontend

• Prototype agent use cases quickly

• Build the product surface (UI, blueprints, examples) that makes AI workflows usable in Kestra

• Work closely with product and the backend team, with a short path from idea to released feature

Our Tech Stack

• 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

We work with a variety of modern technologies, and you’ll get the opportunity to explore new tools and approaches as we grow.

What we are looking for

• Strong full-stack engineering with Java on the backend

• Frontend experience is a clear plus

• Hands-on AI experience: you have built with AI and understand AI agents

• A bias toward building and releasing, balanced with the judgment to know when a prototype is ready for production

Perks & 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.

Before you apply

This is Java-first, so a Python-only AI profile is not a fit. We are looking for production experience, not a portfolio of demos. If you have built and released AI products end to end, this role is for you.
