Cencora is an innovative company dedicated to creating healthier futures. They are seeking a Senior Network Engineer to serve as a technical leader responsible for the design, integration, and optimization of the company's backbone, data center, and cloud network environments, particularly in the context of mergers, acquisitions, and divestitures.
Responsibilities:
- Design and implement large-scale, highly available network solutions spanning backbone WAN, data center fabrics (spine/leaf, VXLAN/EVPN), and cloud environments (AWS, Azure, GCP)
- Own routing architecture across the enterprise — BGP, OSPF, IS-IS, MPLS, and segment routing — ensuring optimal path selection, convergence, and redundancy
- Perform advanced troubleshooting of complex Layer 2/3 issues, including root cause analysis across multi-vendor, multi-domain environments
- Manage capacity planning for backbone and data center interconnects; model growth scenarios and recommend upgrades to meet evolving business needs
- Evaluate and test emerging technologies — SD-WAN overlays, cloud-native networking (Transit Gateway, Azure vWAN), network automation/orchestration, and intent-based networking — for adoption into the core
- Document and maintain high-level and detailed network designs, including redundancy, failover, and disaster-recovery strategies
- Lead the network workstream for each MA&D event end-to-end — from due diligence through Day 1 cutover to steady-state hand-off
- Conduct technical discovery & assessments of target/divested company networks: inventory infrastructure, map IP address spaces, identify overlapping RFC 1918 ranges, catalog circuits, and evaluate security postures
- Develop integration blueprints that define how acquired networks will be absorbed into Cencora's backbone, data center, and cloud environments — including IP re-addressing/NAT strategies, DNS consolidation, routing policy merges, and identity/segmentation alignment
- Architect divestiture carve-out plans that cleanly separate shared network services, circuits, firewall policies, and cloud tenancies while maintaining operational continuity for both entities through the Transition Services Agreement (TSA) period
- Coordinate circuit provisioning and decommissioning — working with carriers, colocation providers, and cloud service providers to stand up or tear down connectivity on schedule
- Manage cutover execution — build detailed migration run-books, lead change windows, and orchestrate cross-functional war-room activities for Day 1 network transitions
- Mitigate risk by designing interim-state architectures (e.g., temporary VPN tunnels, NAT boundaries, shared firewalls) that allow phased integration or separation without disrupting production traffic
- Collaborate cross-functionally with Security, Systems/Server, Cloud, Application, and Identity teams to ensure seamless integration during both BAU operations and MA&D events
- Partner with Project Management and Corporate Development to align network milestones with broader deal timelines, budgets, and business commitments
- Develop and enforce network policies and standards, ensuring compliance with Cencora security and regulatory requirements (e.g., HIPAA, SOX)
- Mentor and guide Level 1 and Level 2 network engineers; serve as the technical escalation point for complex incidents
- Drive automation of repeatable MA&D tasks — templatized configurations, automated compliance checks, scripted IP migrations — to accelerate future integrations
Requirements:
- 7+ years in enterprise network engineering with significant time operating backbone, data center, and/or cloud network infrastructure
- Demonstrated participation in at least 2–3 network integration or carve-out projects (M&A, divestiture, or large-scale migration equivalents)
- Expert-level knowledge of BGP, OSPF, MPLS, VXLAN/EVPN, spanning-tree, and multicast in multi-vendor environments (Cisco, Arista, Juniper, Palo Alto, etc.)
- Hands-on experience with modern data center fabrics, interconnects (DCI), and colocation environments
- Working knowledge of at least one major cloud provider's networking stack (AWS VPC/TGW, Azure vNET/vWAN, GCP VPC)
- Experience with network automation tools and languages — Ansible, Terraform, Python, or equivalent
- Advanced certification preferred: CCNP/CCIE, Advanced Networking, or equivalent
- Strong leadership, project coordination, and communication skills; comfortable presenting to technical and non-technical stakeholders, including corporate development and executive leadership
- Experience in pharmaceutical distribution, healthcare, or other regulated industries
- Familiarity with Transition Services Agreements (TSAs) and the operational constraints they impose on network timelines
- Hands-on experience with network segmentation and zero-trust architectures in the context of integrating untrusted acquired environments
- Exposure to ITSM/change management frameworks (ITIL, ServiceNow) in large enterprise settings
- Working knowledge of network monitoring and observability platforms
