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.

What You’ll Do

As a Lead Software Engineer at Kestra, you’ll get to:

• Build and improve ourcore platform backend using Java.

• Work onenterprise solutions, crafting products that scale with our customers’ needs.

• You oversee engineers asTeam Leader. This involves conducting code reviews, unblocking developers, and providing technical mentorship to help junior and senior staff grow.

• Youact as the translator between technical and non-technical departments. You’ll work with Product Managers to define roadmaps and ensure technical debt is balanced with feature delivery.

• You own thequality of the software. This includes overseeing CI/CD pipelines, defining SLOs/SLAs (Service Level Objectives), and leading "Post-Mortems" when systems fail.

• You workclosely with customers to understand and fix their pain.

You’ll be working in an environment where speed and agility are key, and where delivering value to our customers is always the top priority.

We embrace modern development tools, including AI assistants and coding agents, and we encourage engineers to leverage them to move faster, explore ideas, and improve productivity. We provide access to leading AI models and tools when needed so you can use them effectively in your daily work.

That said, we strongly believe great engineers must fully understand what they build. This means mastering the business context, the architecture, performance considerations, security implications, and quality standards of the code being produced. You should be comfortable reviewing, validating, and improving AI-generated code, and ultimately take ownership of the entire lifecycle from understanding the problem and designing the solution, to implementation, testing, and delivery. AI can accelerate the work, but responsibility, critical thinking, and technical judgment always remain with the engineer.
