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

Job summary

ARX Robotics is seeking a Senior Infrastructure Engineer to operate the infrastructure that supports next-generation autonomous robotic systems across hybrid and restricted environments. This role involves building and maintaining the operational backbone for secure, reliable, and recoverable engineering and deployment environments, working hands-on across Linux systems, networking, storage, monitoring, backup, and recovery.

Qualifications

• 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 infrastructure engineering.
• Experience with VS-NfD environments, defense-sector IT, SINA-based systems, classified infrastructure, or accreditation-oriented operations is highly valuable.
• Familiarity with at least one major cloud platform or sovereign cloud environment, especially around networking, IAM, logging, compute, storage, or infrastructure-as-code, is beneficial.
• Experience with monitoring and observability platforms such as Grafana, Prometheus, Loki, ELK, or Zabbix is beneficial.
• Personal projects or experience related to Linux, self-hosting, networking, hardware, or home lab environments are highly appreciated.

Responsibilities

• 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.
• 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.
• Participate in incident response, recovery testing, operational readiness, and future on-call operations.
• Contribute to documentation, operational runbooks, and long-term infrastructure reliability practices.
