Hybrid

About The Position

McKesson is seeking a Sr. Network Engineer & Warehouse Operations professional for a hybrid role in Richmond, VA. This position is part of a significant transformation involving a carve-out and migration to a cloud-first operating model, focusing on network discovery, future-state architecture design, migration planning, and execution, particularly in distribution centers and warehouse facilities. The role requires hands-on involvement in network cutovers, device network management, and hybrid cloud connectivity to GCP, with a strong emphasis on documentation and knowledge transfer.

Requirements

  • Degree or equivalent and typically requires 7+ years of relevant experience.
  • Proven track record leading network cutovers at physical sites (distribution centers, warehouses, manufacturing facilities, or equivalent operationally sensitive environments).
  • Direct experience with network discovery and dependency mapping at scale.
  • Experience designing and executing migration wave plans in enterprise carve-out, M&A, or large-scale transformation programs.
  • Hands-on experience with GCP networking (VPC, Cloud Interconnect, Cloud VPN, Cloud DNS, Cloud Armor) or equivalent cloud networking with demonstrated ability to transition to GCP.
  • Experience with SD-WAN platforms (Cisco, Aruba) and cloud-managed WAN transformation.
  • Warehouse or distribution center networking experience including RF/wireless planning, device network management, and coordination with WMS and operations teams.
  • Expert-level troubleshooting and design capability in Network Protocols: BGP, OSPF, EIGRP, MPLS, VRF, HSRP/VRRP, STP, 802.1Q, QoS, IPSec.
  • Experience with Physical Site Networking: Campus switching (Cisco, Juniper, Aruba), wireless (802.11ax and prior), structured cabling, rack/stack and field installation.
  • Experience with Cloud Networking: GCP VPC, Shared VPC, Cloud Interconnect, Cloud VPN, Cloud Router (BGP), Cloud NAT, Cloud DNS, VPC Service Controls, Network Intelligence Center.
  • Experience with Firewall & Security: Palo Alto, Cisco ASA/FTD, or equivalent — policy migration, zone-based segmentation, NAT, and Zero Trust network access patterns.
  • Experience with Infrastructure as Code: Terraform for network resource provisioning; Git-based change management for network configurations.
  • Experience with Monitoring & Observability: Network monitoring platforms (SolarWinds, PRTG, Grafana, or equivalent), VPC Flow Logs, Cloud Monitoring, packet capture and analysis (Wireshark).
  • Experience with Wireless & Device Networks: RF survey and design, DHCP/DNS for dense device environments, 802.1X, MAC authentication, device onboarding at scale.
  • Bachelor’s or master’s degree in computer science, Data Science, Information Technology, or a related field OR equivalent experience.
  • Google Professional Cloud Network Engineer — required or to be obtained within 6 months of start.

Nice To Haves

  • CCNP Enterprise or CCIE Enterprise Infrastructure — strongly preferred, a clear differentiator for this role.
  • SD-WAN vendor certification (Cisco ENSDWI, VMware SD-WAN, or equivalent) — desirable.
  • Project Management Professional (PMP) or equivalent — desirable for wave planning and program coordination responsibilities.
  • Equinix global data center offering Physical Colocation.

Responsibilities

  • Conduct structured discovery of all network environments, inventorying physical network infrastructure, and mapping application/service dependencies.
  • Document current-state network topology, including VLAN structure, IP addressing, routing protocols, and WAN/MPLS connectivity.
  • Identify and flag latency-sensitive or operationally critical network paths.
  • Design the target-state network architecture for a GCP-centric, cloud-first operating model, including GCP network foundation, SD-WAN/cloud-managed WAN strategy, and network segmentation for OT/IoT device networks.
  • Design wireless network architecture for warehouse and campus environments.
  • Produce architecture decision records (ADRs) for significant design choices.
  • Translate discovery and architecture outputs into a structured, sequenced migration program with clear wave definitions, dependencies, and go/no-go criteria.
  • Build wave plans including scope, pre-requisites, rollback procedures, communication, testing, and cutover windows.
  • Identify and resolve cross-wave dependencies and coordinate wave planning with other program workstreams.
  • Maintain a living migration tracker visible to program leadership.
  • Lead hands-on cutover execution for each migration wave, including on-site presence at distribution centers and warehouse facilities.
  • Lead pre-cutover readiness reviews, confirm dependencies, test rollback procedures, and establish communication bridges.
  • Execute network cutovers during defined maintenance windows.
  • Manage on-site network cutovers, coordinating with operations teams, shift supervisors, and WMS owners.
  • Execute post-cutover validation checklists.
  • Own rollback execution when cutover criteria are not met.
  • Understand and account for device network requirements in warehouse and distribution center environments, including DHCP reservation, RF planning, device authentication, polling frequency, and latency tolerance.
  • Coordinate device network changes with operations and WMS teams.
  • Validate all operational devices post-cutover.
  • Establish and validate network connectivity between physical sites and GCP, ensuring performance to SLA.
  • Configure and validate Cloud Interconnect or Cloud VPN, with appropriate bandwidth provisioning and redundancy.
  • Define and enforce QoS policies for ERP and latency-sensitive application traffic.
  • Work with the Integration Architecture team to validate integration traffic flows.
  • Implement network observability tools and integrations.
  • Maintain comprehensive current-state and target-state network documentation.
  • Produce runbooks for standard operational procedures.
  • Transfer knowledge to the NewCo operations team as each wave completes.
