    • Design and maintain networking architecture including VLANs, L2/L3 routing, VPNs, and multi-site connectivity.

    • Build automated deployment workflows (PXE boot, Preseed, cloud-init).

    • Deploy and maintain observability stacks (Prometheus/Grafana, Loki, ELK, Graylog).

    • Lead incident response and escalation activities across the platform.

    • Improve system availability and reduce latency at all levels.

    • Define and implement SLOs/SLIs at multiple infrastructure levels (physical network/hardware, platform virtualization, software services).

    • Optimize alerting and monitoring pipelines to provide actionable insights.

    • Establish and maintain on-call schedules to ensure coverage across timezones.

    • Develop Standard Operating Procedures (SOPs) for repeatable operations and maintenance tasks.

    • Coordinate physical maintenance for Policlouds (periodic maintenance, hardware issues, DC-Ops).

    • Manage virtualization and orchestration layers (OpenStack, Proxmox, VMware).

    • Help develop and maintain overall architecture across all products.

    • Plan resources for future initiatives, accounting for demand and growth projections.

    • Work with development teams to improve overall quality and optimize resource utilization.

    • Collaborate with cross-functional stakeholders (Hivenet, Policloud, Customer Success teams).

    Requirements

    • Expert-level, hands-on experience operating Kubernetes in production environments.

    • Strong network engineering skills (VLANs, L2/L3 routing, VPNs, multi-site connectivity) - this is essential for the role.

    • Strong proficiency with Linux systems administration (Debian/Ubuntu).

    • Solid understanding of networking fundamentals and ability to design complex network architectures.

    • Experience building and maintaining automation workflows (Ansible, Bash/Python, Git-based).

    • Background with virtualization technologies (OpenStack, Proxmox, VMware).

    • Experience with bare-metal provisioning and MAAS (Metal as a Service).

    • Strong understanding of distributed systems and container orchestration.

    • Process-oriented mindset with ability to develop SOPs and operational procedures from scratch.

    • Experience with incident response, escalation procedures, and on-call rotations.

    • Ability to work autonomously in a fast-paced, engineering-driven environment.

    • Strong technical skills combined with alignment to team values.

    Nice To Have
