About this opportunity

Your Role

In this pivotal role, you will serve as a global technical expert for Windows Server infrastructure, driving the reliability, security, and performance of critical systems that underpin operations worldwide. You will own the full lifecycle of Windows Server environments, from architecture and deployment through hardening, patch management, and vulnerability remediation, while leading automation initiatives that eliminate manual effort and elevate operational standards. You will act as the primary escalation point for complex infrastructure challenges, conducting root cause analysis and problem management to prevent recurrence. Collaborating with cross-functional teams, you will translate business requirements into scalable infrastructure solutions, represent the Windows domain in global audits, and champion disaster recovery planning and execution. Your expertise will also extend to datacenter governance, hardware asset management, and the deployment of monitoring capabilities for power, cooling, and environmental controls.

Who You Are

Proven ability to design and implement automation solutions using tools such as Ansible, PowerShell, or equivalent scripting frameworks to reduce manual effort at scale.

Strong background in patch and vulnerability management for Windows Server and virtualization infrastructure, with the ability to interpret and act on vulnerability data.

Experience in datacenter operations, including hardware lifecycle management, asset tracking, and environmental monitoring for power and cooling systems.

Solid understanding of IT service management frameworks (ITSM/ITIL), change management processes, and audit readiness in enterprise environments.

Familiarity with cloud technologies and hybrid infrastructure concepts, including experience with platforms such as Azure Arc or equivalent cloud management tooling.

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
