'Job Description: Senior Private Cloud Network Engineer (Standalone IPv6)

We are seeking a Senior Network Engineer to manage the core fabric of a fully isolated, standalone private cloud. This environment is "dark " (no external traffic) and utilizes a multi-VPC architecture. You will be the primary authority on our Centralized IPv6 Management VPC , ensuring that any OS—regardless of flavor or version—communicates flawlessly within our internal ecosystem.

Key Responsibilities

1. Agnostic OS Integration: Expertly deploy and troubleshoot IPv6 on any Windows version (Server/Desktop) and any Linux distribution (Debian, RHEL, SUSE, Alpine, etc.).
2. Centralized Management: Oversee the primary Management VPC that provides all core services (IPAM, DHCPv6, DNS) to the rest of the private cloud VPCs.
3. Isolated Fabric Architecture: Maintain the Layer 2/3 boundary using VXLAN or EVPN to ensure VPC isolation in a 100% on-premises, standalone environment.
4. Internal Routing Mastery: Manage internal BGP or OSPFv3 to handle traffic between VPCs without any external gateway dependency.
5. Kernel & Registry Tuning: Conduct in-depth troubleshooting of Linux sysctl settings and Windows Registry keys to optimize IPv6 stack behavior, particularly regarding Neighbor Discovery and Privacy Extensions.

Technical Requirements

1. Universal IPv6 Knowledge:
   1. Mastery of Unique Local Addresses (ULA) and Link-Local addressing.
   2. Expertise in ICMPv6 diagnostics within a closed loop (Neighbor Solicitations, Router Advertisements).
   3. Ability to implement Stateful and Stateless DHCPv6 to accommodate varying OS requirements.
2. Multi-Platform Networking:
   1. Windows: Proficiency in PowerShell and netsh for complex IPv6 interface configurations and managing internal-only Active Directory networking.
   2. Linux: Expert knowledge of the various networking stacks ( systemd-networkd , NetworkManager , ifupdown ) and manual iproute2 command usage.
3. Private Cloud Fabric: Experience with virtualized networking (OVS, Bridge-utils) and how hypervisors (KVM, ESXi, etc.) handle IPv6 multicast traffic.
