Senior Linux Appliance Engineer - Edge Platform

Join Milestone and build infrastructure that feels like a product!

Impact & Purpose

We are building a Linux-based software appliance that customers can install,
upgrade, operate, and recover with confidence in real-world environments.

Some deployments will run on customer-controlled hardware. Some will be
airgapped. Some will have limited or intermittent connectivity. Many will be
operated by people who should not need to become Linux or Kubernetes experts to
keep the system healthy.

This is not primarily a cloud platform role. You should be comfortable working
below Kubernetes: Linux bootstrapping, system services, networking, storage,
installation media, offline artifacts, upgrades, rollback, diagnostics, and
recovery.

Kubernetes is part of the platform, but the hard part is making the whole
appliance lifecycle reliable, repeatable, and supportable.

Location:

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

Role Summary

As a Senior Linux Appliance Engineer, you will help design and build the
foundation for a turnkey on-premise and edge platform used in hybrid, offline,
and airgapped environments.

You will work across Linux, automation, container runtime, Kubernetes,
installation flows, upgrade mechanisms, recovery paths, diagnostics, and
operational tooling. The goal is not just to make infrastructure work once. The
goal is to make it work predictably across many customer installations, hardware
profiles, and lifecycle events.

This is a hands-on engineering role with strong technical ownership and
influence on architecture, product quality, engineering standards, and long-term
operability.

What You Will Do:

* Design and evolve a production-grade Linux software appliance for edge and
on-premise deployments.
* Build reliable install, upgrade, rollback, factory reset, and recovery
workflows.
* Work on Linux system configuration, bootstrapping, services, networking,
storage, logging, hardening, and troubleshooting.
* Support offline and airgapped operation, including artifact packaging, local
registries, dependency handling, and upgrade bundles.
* Help define the boundary between the host OS, Kubernetes, platform services,
and application workloads.
* Create automation and guardrails that reduce manual operations and make
customer installations supportable.
* Improve observability, diagnostics, and support tooling so failures can be
understood without heroic manual access.
* Collaborate with product, engineering, support, and customer-facing teams to
turn complex infrastructure into a product experience.
* Shape engineering practices around reliability, lifecycle management,
testing, release quality, and operational safety.

What You Bring to the Team

We are looking for a strong systems engineer with deep hands-on experience in
Linux and production environments:

* Linux systems in production, including troubleshooting, networking, storage,
logs, security hardening, and performance.
* Building or maintaining systems that run outside normal cloud environments,
such as appliances, edge systems, industrial systems, embedded Linux devices,
on-prem platforms, or customer-managed infrastructure.
* Installation, provisioning, patching, upgrade, rollback, backup, recovery, or
lifecycle automation.
* Automation using tools such as Ansible, Bash, Python, Go, Terraform,
Ignition, Kickstart, preseed, or similar.
* Containers and container runtimes such as Docker.
* Practical Kubernetes experience, especially around node behavior, networking,
storage, resource usage, observability, and troubleshooting.
* Working with restricted or offline environments, including local package
mirrors, registries, signed artifacts, version manifests, or dependency
bundles.

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.
