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.
