Linux Infrastructure Security Expert (m/f/d)

Linux Infrastructure Security Expert (m/f/d)

We are looking for a Linux Infrastructure Security Expert to build a modern, resilient and secure platform used by hundreds of engineers across the R&D organization. This role is intended for senior engineers with experience with internal and external cloud infrastructures in a Linux environment.

What you’ll do

• Own and continuously harden our internal service landscape — Kubernetes, virtualization, and automation (Ansible) — with security as a first principle, not an afterthought.
• Drive iterative improvements to our k8s cluster infrastructure and set the bar for how we build and operate R&D applications at scale.
• Architect, build, and run infrastructure for web and backend applications used by engineering teams worldwide.
• Stay ahead of the curve — evaluate emerging technologies and make the call on what actually moves the needle for us.
• Collaborate directly with engineers across Germany, the US, China, and Japan. Different time zones. Different perspectives. One shared goal.

What you bring

• Deep Linux expertise — you're equally comfortable tuning kernel parameters and debugging a misbehaving service. You own the full stack.
• Solid hands‑on experience setting up, operating, and securing Kubernetes clusters in production environments.
• A track record of designing and maintaining complex, secure service infrastructures — not just running them, but making them better.
• Programming fluency in one or more of: Python, Go, JavaScript/TypeScript, or equivalent. You write code that others are glad to maintain.
• Real‑world experience with public cloud (AWS or Azure) — you know how to build infrastructure that scales without bleeding money or security.

Bonus points

• Experience with Red Hat Linux
• Background in semiconductor testing or the semiconductor industry
• German, Japanese, or Chinese language skills — always a plus in a truly global team
