About the role

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 Infrastructure Engineer (Linux & Platform) , based in Barcelona, Spain (hybrid mode of working).

Role Summary

As a Senior Infrastructure Engineer (Linux & Platform), you will design and build a turnkey on-prem platform used in on-premisses, hybrid and air-gapped environments.

You will focus on reliability, automation, lifecycle management, and operational simplicity - turning complex infrastructure into a seamless product experience. While the platform leverages Kubernetes, this role is Linux and systems-first, with Kubernetes as one part of the broader stack.

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

What You Bring to the Team:

We are looking for a strong generalist engineer with deep experience in Linux systems and production environments, and some exposure to Kubernetes and container platforms. If your background aligns with many of the areas below, we encourage you to apply.

Strong software engineering experience in backend, systems, or infrastructure development

Deep hands-on experience with Linux in production environments (troubleshooting, performance, networking, system behavior)

Experience working with containers and Docker

Practical familiarity with Kubernetes (concepts, basic operations, troubleshooting)

Experience with infrastructure automation tools such as Ansible (or similar)

Familiarity with API design and contracts (REST, gRPC, OpenAPI)

A focus on reliability, maintainability, and operational 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, real-world 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 systems and lifecycles - not just components. 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

Supportive leadership and regular feedback

Opportunities for cross-functional and cross-regional collaboration

Social activities and spaces to connect with colleagues

What We Offer:

Gym contribution

Food vouchers + flexible retribution

Luxury health and dental package

Bicing annual fee reimbursement

Life insurance

About the Team

We care about building dependable systems, strong engineering foundations, and products that are simple to operate. We value thoughtful collaboration, practical solutions, and continuous improvement over unnecessary complexity.

If this role sounds exciting, but you don’t match every qualification, we still encourage you to apply. We value diverse perspectives, curiosity, and engineers who care deeply about building reliable products.
