IT-OT Linux Engineer

IT-OT Linux Engineer for cloud-connected edge platforms.

At Schuberg Philis, you do not disappear into a ticket queue. You become part of a small, autonomous team that owns a mission critical platform end to end. We design, build, and run Linux based systems that sit close to the real world: in plants, warehouses, and other industrial and edge locations where failure actually hurts.
We are looking for a IT-OT Linux Engineer who loves working with Linux in a practical, hands-on way. You will create robust platform images, keep systems predictable with immutable deployments, and make sure services start, stop, and recover exactly as intended. Most of your work lives on Linux at the edge; your AWS experience is a bonus, especially if you like connecting those systems to the cloud using services like AWS IoT and AWS IoT Greengrass. You will help shape how we build and operate these platforms: from how we version and roll out images, to how we monitor remote sites on flaky 4G links, to how we containerize applications on resource constrained boxes. You are close to the technology, but also close to the impact.

What You Will Do

• Build and maintain Linux platform images that are designed to be stable, repeatable, and easy to upgrade.


• Use immutable root filesystem concepts (for example with OSTree) so that updating devices is safe and reversible.


• Define and manage systemd services so applications behave predictably, even after power loss or unstable networks.


• Run applications in containers using tools like Podman, tuned for small systems rather than huge clusters.


• Automate everyday work with shell scripting so diagnosing, updating, and deploying to many nodes stays manageable.


• Work in a Git based workflow, reviewing changes with your teammates and continuously improving the platform.


• Deal with real world constraints: devices with little RAM, intermittent 4G connectivity, and serial connections to field equipment.


• Collaborate with security, data, and cloud engineers to connect your Linux platforms to wider solutions.

What Makes This Role Interesting

• Real world impact: Your work runs in places where downtime stops operations. You see clear results from making systems more robust and easier to operate.


• End to end ownership: You are not just “the OS person” or “the cloud person.” You help design, build, run, and evolve the platform as a whole.


• Modern Linux engineering: Immutable systems, systemd, Podman, Git driven workflows, automated rollouts. You get to apply these ideas in production, at scale.


• Edge and OT challenges: You work on problems you will not find in pure cloud: low bandwidth links, rugged hardware, tight resource limits, and long lived devices that must remain secure and manageable.


• Room to grow: You can deepen your Linux and IT/OT expertise or grow toward broader DevOps and platform roles, including more cloud and AWS if that excites you.

What You Bring

You most likely:

• Are experienced with Linux system administration and enjoy understanding how things really work under the hood.


• Use or want to use immutable deployment techniques to make systems more reliable.


• Are comfortable with systemd, containers on Linux (for example Podman), and shell scripting.


• Work with Git as a normal part of your day.


• Are curious about or experienced with IT/OT or embedded like environments, especially where hardware and connectivity are not perfect.

It is a plus if you:

• Know the Red Hat family (RHEL, CentOS, Fedora).
  Have worked with resource constrained systems, cellular connectivity, or serial protocols such as RS 485.


• Have experience with AWS, especially AWS IoT and AWS IoT Greengrass, or managing edge devices that talk to cloud services.

If you’re excited about taking real ownership of Linux platforms that matter, solving tricky edge and OT problems with modern tools, and working in a team that trusts you to make sound engineering choices, this could be a great fit. You do not need to tick every box. If you can cover most of the essentials, we’d love to hear from you.
