Mission Brief
We are seeking a hands-on Manager Network & Systems Administration to lead, maintain, and modernize our hybrid infrastructure. In this role, you will act as both a technical lead and an infrastructure owner, bridging our on-premise virtualization, enterprise networking, and multi-cloud environments.
This is a hands-on lead position designed for a senior engineer who excels at architecture, network engineering, and troubleshooting while serving as the primary technical authority for our infrastructure. You will be responsible for end-to-end reliability, system security, network connectivity, and overseeing automated deployment workflows—from bare-metal hypervisors to cloud routing.

Technical Leadership & Operations
- Hands-on Infrastructure Leadership: Serve as the primary technical subject matter expert (SME) and escalation point for all systems, virtualization, and network architecture.
- Vendor & Asset Management: Oversee infrastructure vendor relationships, license agreements, hardware lifecycles, and service level agreements (SLAs).
- Incident & Capacity Planning: Lead major incident responses, perform root-cause analysis (RCA), and proactively monitor capacity across storage, compute, and network links.
Multi-Cloud & Virtualization Management
- Hybrid & Multi-Cloud Administration: Design, secure, and maintain scalable infrastructure across Azure, AWS, and IONOS Cloud.
- On-Premise Virtualization: Oversee, optimize, and maintain our enterprise hypervisor clusters using VMware vSphere (ESXi/vCenter) and Proxmox VE (KVM/LXC).
- Disaster Recovery & Data Protection: Plan, implement, and test automated backup, recovery, and high-availability strategies across all platforms.
- Infrastructure Automation Concepts: Understand and support Infrastructure as Code (IaC) workflows (Terraform/Ansible) to streamline server provisioning, configuration management, and patching.
Enterprise Networking & Security
- Network & Connectivity Management: Design, configure, and troubleshoot complex network architecture involving Cloud VPCs, Site-to-Site IPsec VPNs, VLAN segmentation, DNS, DHCP, and firewalls.
- Traffic Management: Manage load balancing, ingress routing, and perimeter security to ensure high availability and zero-trust access principles.
