More about the role & team

Hands-on infrastructure security role with real ownership and visible impact

We’re looking for a senior infrastructure professional who enjoys solving practical security challenges and improving how security is delivered across enterprise systems. This role sits within the IT Infrastructure team and works closely with Cybersecurity, with a strong focus on implementation, remediation, and secure operations across Windows and Linux environments.

This is not a purely advisory or monitoring position. You’ll take direct ownership of vulnerability remediation, help improve patching cycles, and ensure systems are securely configured and operationally resilient. You’ll also contribute to key initiatives including certificate lifecycle management and the operational use of security platforms such as Privileged Access Management and Cloudflare.

If you enjoy hands-on work, broad technical exposure, and the opportunity to improve security posture in a meaningful way, this is a role where you can make a clear and measurable difference

Why should you apply?

Take ownership of vulnerability remediation across enterprise systems, helping reduce backlog and improve remediation delivery at scale. Improve patching cadence, configuration hygiene, and secure operational practices across infrastructure environments. Administer and harden Windows Server environments, including Active Directory, Group Policy, DNS, authentication, and certificate services, with supporting Linux administration. Support certificate lifecycle management, including TLS/PKI, renewals, and ongoing certificate operations. Work with core security platforms such as PAM solutions and Cloudflare, and support logging and monitoring platforms such as Sumo Logic or Splunk. Partner closely with Cybersecurity and infrastructure stakeholders to implement approved controls, remediate findings, and improve how security is operationalized across environments.

Applicants must be within a commutable distance (within 2 hours or 80 miles) of one of the listed offices
