Proxmox Consultant / VMware - European Commission (Brussels)

Proxmox Consultant / VMware - European Commission (Brussels) Bridge351 is a tech company focused on excellence, innovation and tailored solutions, operating across Europe in areas like Cloud, Cybersecurity, Data and Advanced Development. Proxmox Consultant – VMware / Hyper-V to Proxmox Migration 🏛️ About the Role The European Commission is consolidating and migrating production and non-production workloads away from VMware vSphere/ESXi and Microsoft Hyper-V onto Proxmox VE. We are looking for a hands-on Proxmox consultant who has done this before — someone who can assess the existing environment, design the target Proxmox architecture, plan and execute the migration with minimal downtime, and leave behind clean documentation and an internal team that can run it. This is a delivery-focused role, working closely with infrastructure, networking, and security teams. 🛠️ Key Responsibilities Assess the current VMware (vSphere / ESXi / vCenter) and Hyper-V (incl. SCVMM where present) environments — inventory, dependencies, storage, networking, and licensing exposure. Design the target Proxmox VE architecture: cluster topology, storage backend (Ceph / ZFS / NFS / iSCSI), networking (Linux bridges, bonding, VLANs, SDN), high availability, and backup strategy. Plan and execute VM migrations using appropriate methods and tooling (Proxmox import wizard, qemu-img conversion, virt-v2v, Veeam, cold/warm/live cut-over) with rollback plans. Stand up and configure Proxmox clusters, Proxmox Backup Server, HA groups, and monitoring/alerting. Validate migrated workloads (performance, drivers/VirtIO, guest tooling, boot, networking) and tune for production. Define and document migration runbooks, cut-over plans, and operational procedures. Handle decommissioning of source infrastructure and reclaim/repurpose hardware where applicable. Manage certificates and PKI material for the Proxmox web UI, API, and cluster communication (certificate lifecycle, renewals, internal CA). Provide knowledge transfer and training so internal staff can operate and maintain the platform. Report progress against milestones and surface risks early. ✅ Mandatory Experience Demonstrable experience delivering at least one production migration from VMware and/or Hyper-V to Proxmox VE. Solid Proxmox VE and Linux administration background. Hands-on experience with Ceph or ZFS in production. Comfort with VM conversion tooling and live/cold cut-over techniques. VMware experience — vSphere / ESXi / vCenter, including VM export/conversion to KVM/QEMU. Hyper-V experience — Hyper-V / SCVMM, VHD/VHDX handling and conversion. Linux system administration — Debian-based systems, shell, services, kernel/storage troubleshooting. Network and security operations — Linux networking, VLANs, bonding, firewalling, SDN; PKI certificate lifecycle management. ⭐ Preferred Qualifications & Experience Proxmox certification or equivalent demonstrable track record. Experience with the post-Broadcom VMware licensing landscape and cost-reduction migrations. Ansible / Terraform / Infrastructure-as-Code experience. Experience with Proxmox SDN, clustering at scale, or multi-site/DR designs. Familiarity with monitoring stacks (Prometheus / Grafana / Zabbix). Automation and scripting — Bash and/or Python. IT service management awareness — ticketing, CMDB tooling, contributing to internal policies and IT security concepts. 🌐 Languages English advanced 📍 Location & Work Model Brussels, Belgium Hybrid Full‑time Locations Bridge351 Brussels Remote status Hybrid
