Join Milestone and build infrastructure that feels like a product!

Impact & Purpose

If you enjoy solving complex systems challenges while creating simple user experiences, we’d love to hear from you.

We are building a cohesive platform experience that customers can install, upgrade, and operate with confidence without needing deep Kubernetes or Linux expertise.

Location:

We are looking for a Senior Kubernetes Engineer (Flexibility Linux Platform), based in Barcelona, Spain (hybrid mode of working).

Role Summary

As a Senior Kubernetes Engineer (Flexibility Linux Platform) you will design and build a turnkey on-prem platform used in on-premises, hybrid and air-gapped environments with deployment flexibility in mind.

You will focus on reliability, automation, lifecycle management, and operational simplicity turning Kubernetes-based infrastructure into a seamless product experience. This is a hands-on engineering role with strong technical ownership and influence on architecture, quality, and engineering standards.

What You Will Do:

• Design and evolve a production-grade software appliance
• Build reliable install, upgrade, rollback, and recovery workflows
• Create automation and guardrails that simplify operations
• Develop backend services and APIs (REST, gRPC, OpenAPI)
• Improve observability, resiliency, and operational safety
• Support air-gapped deployments and offline upgrades
• Collaborate with product, support, and customer-facing teams
• Help shape engineering practices and technical direction

• A focus on reliability, maintainability, and product quality
• Clear communication and collaborative problem solving

How You will Make a Difference:

• You will help create a platform that customers can trust to run reliably in complex environments with minimal operational overhead. Your work will reduce infrastructure complexity and make powerful systems easier to deploy, manage, and support.
• We value engineers who think in terms of products and lifecycles not just services. You design for reliability, upgrades, rollback, and long-term maintainability, with a focus on simplicity, predictability, and operational clarity.

How We Support You:

• Individual development plans aligned with your career goals
• Access to training, learning resources, and certification
• Flexible working arrangements
