Senior Infrastructure Engineer, Linux, Network & Physical Systems (m/f/d)

Back to jobsSenior Infrastructure Engineer, Linux, Network & Physical Systems (m/f/d)MunichAPPLYAbout the role At ARX Robotics, you will operate the infrastructure that supports next-generation autonomous robotic systems across hybrid and restricted environments. As a (Senior) Infrastructure Engineer – Linux, Network & Physical Systems, you will help build and maintain the operational backbone behind secure, reliable, and recoverable engineering and deployment environments.  While the role is not primarily a cloud engineering role, ARX operates in a hybrid reality across physical infrastructure, restricted environments, public cloud, and SaaS. You should therefore be comfortable working at the boundaries between on-prem systems, cloud platforms, identity, networking, monitoring, and security controls.  This role is designed for someone who genuinely enjoys infrastructure engineering. Whether you run a home lab, self-host services, build networks for fun, or care deeply about reliable Linux systems and clean operational practices, your mindset will fit well here. You will work hands-on across Linux systems, networking, storage, monitoring, backup, and recovery while helping shape scalable infrastructure operations for demanding and security-conscious environments.  What You’ll Build Operate and maintain Linux servers, virtualization platforms, storage systems, backups, and monitoring infrastructure   Configure and troubleshoot physical networking including switches, VLANs, routing, firewalling, cabling, and rack/server infrastructure   Support VPN, ZTNA, DNS, routing, segmentation, and hybrid connectivity across operational environments   Build and maintain hardened infrastructure baselines, patch management processes, backup verification, and recovery procedures   Contribute to secure and scalable infrastructure operations across restricted and non-restricted environments   Establish and improve monitoring, alerting, logging, and operational observability for critical systems   Support controlled infrastructure operations including access management, audit logging, environment separation, and operational evidence collection   Help maintain clear operational boundaries between public, internal, and restricted infrastructure environments   Automate repetitive operational tasks using scripting and infrastructure tooling   Support cloud-connected infrastructure patterns, including identity federation, logging export, monitoring integration, backup paths, and secure connectivity between physical, virtual, and cloud environments.  Work with platform and cloud engineers on infrastructure-as-code, landing-zone guardrails, and operational standards where Linux, networking, storage, or hybrid connectivity meet public cloud infrastructure.  Participate in incident response, recovery testing, operational readiness, and future on-call operations   Contribute to documentation, operational runbooks, and long-term infrastructure reliability practices   What You Bring Strong hands-on experience operating and maintaining Linux-based systems in production environments   Solid understanding of networking fundamentals including TCP/IP, DNS, routing, VLANs, VPN/ZTNA, firewalling, and segmentation   Experience managing physical or virtual infrastructure including servers, storage systems, virtualization platforms, backups, and monitoring solutions   Confidence troubleshooting issues across Linux systems, networking, storage, and infrastructure operations   Experience automating workflows using Bash, Python, Ansible, Terraform, or similar tooling   Security-conscious mindset with practical experience in access management, patching, logging, and operational separation   Understanding of the discipline required in restricted or regulated environments, including least-privilege access, documented changes, backup verification, and controlled information handling   Strong analytical and organizational skills with a practical, hands-on approach to...
