McKesson Medical‑Surgical (MMS) is a subsidiary and publicly reported segment of the McKesson Corporation. MMS distributes medical‑surgical supplies, pharmaceuticals, diagnostic equipment and supplies, along with other solutions and services to virtually every type of healthcare setting and provider outside of the traditional hospital. These markets – often referred to as Alternate Care or Non‑Acute Care – include physician offices, surgery centers, long‑term care providers, laboratories, home health and hospice agencies, health systems, government facilities and online marketplaces and retailers.

Alternate Care markets are growing rapidly and MMS is proud to be a leader in this space. With a team of approximately 8,000 employees, a network of 15 distribution centers and approximately 900 delivery vehicles, we partner with more than 2,200 leading manufacturers and serve over 200,000 customer accounts across the U.S. Our catalog includes more than 280,000 SKUs of branded and private‑label medical‑surgical products – from bandages to specialty pharmaceuticals and COVID‑19 tests.

McKesson has announced its intent to separate MMS into an independent company – an exciting evolution that builds on MMS’s strong foundation and proven leadership in the Alternate Care space. As a standalone company, MMS would be positioned to unlock new opportunities to innovate, grow and lead with even greater agility and focus. We will also continue to be one of the largest medical‑surgical distributors in the U.S., with over $11B in annual sales.

This separation would accelerate our mission and empower us to shape a future defined by customer‑centricity, bold thinking and operational excellence. For job seekers, it’s a unique moment to join a team that’s already making a meaningful impact and leading the way in shaping the future of healthcare delivery in Alternate Care settings – with even greater opportunity ahead as we prepare to become an independent company.

• Map application and service dependencies on the existing network topology identifying which workloads, integrations, and operational systems have hard dependencies on current addressing, routing, or latency characteristics.

• Document current‑state VLAN structure, IP addressing schemes, routing protocols, WAN/MPLS topology, and site‑to‑site connectivity in sufficient detail to design against.

• Identify and flag all latency‑sensitive or operationally critical network paths (ERP transactions, warehouse device polling, distribution operations) that require special handling during migration.

• Produce dependency maps and site network profiles as formal migration inputs, not informal notes.

• Design the target‑state network architecture for New Company, aligned to a GCP‑centric, cloud‑first operating model, covering all site types in scope.
