Product Software Engineer

Location: Europe (Time zone: CET: +/- 4h) or on-site/hybrid in Hamburg, Germany. We are a remote-first company.

About Us

Kubermatic is an adaptable and autonomous software delivery startup based in Hamburg (founded Our tools are built with Kubernetes and cloud-native solutions to deliver the automated, flexible, and resilient infrastructure that modern businesses need to thrive and innovate.

We're maintainers of CNCF Sandbox Project kcp and among the leading European corporate contributors to Kubernetes. Our engineering team actively contributes to CNCF projects and open-sources our core products on GitHub. We regularly present at industry conferences and community events.

You'll be joining the KDP (Kubermatic Development Platform) team, which brings self-service developer platforms to enterprises. KDP leverages kcp to deliver a novel approach for building multi-tenant platforms. By providing a centralized catalog, it simplifies the creation, integration, and management of services, greatly lowering the operational burden for DevOps, platform, and developer teams.

We're a fast-moving startup with a strong engineering culture. If you're excited about experimentation, technology, and making a real impact, you'll thrive here. There's plenty of room for your ideas and growth

Role Summary

As a product engineer on our 5-person team, you'll drive features from discovery to delivery and shape architectural and product decisions. You'll engage directly with users to understand their challenges and pain points. We work closely as a team, often pairing on features to deliver high-quality software faster. Our development approach emphasizes tracer-bullet development—getting working solutions in front of customers early—followed by iterative refinement.

You'll work primarily in Go, developing Kubernetes operators and high-availability services that power our platform. KDP is currently available as a standalone, on-premises solution, and as we prepare to launch a new SaaS offering, you'll help evolve our tech stack to meet these emerging requirements.

What Will You Be Doing?

• Design, build, and refine KDP features with a focus on user value and technical excellence.
• Break down implementations into iterative deliverables and determine optimal rollout strategies.
• Develop scalable services and Kubernetes Operators in Go that power our platform.
• Own features end-to-end—from discovery through delivery—including direct engagement with users.
• Stay current with customer challenges and emerging trends in the platform engineering space.
• Contribute patches to upstream projects such as when opportunities arise.
• Extend the MCP server for KDP and integrate with leading AI tools.
  Participate in the on-call rotation.
