More about the role & team

This role focuses on strengthening infrastructure security by directly implementing and remediating security controls across enterprise systems. It sits within the IT Infrastructure team and works closely with Cybersecurity, with a clear emphasis on execution—addressing vulnerabilities, improving patching cycles, and ensuring systems are securely configured across Windows and Linux environments.

A key priority for this role is reducing a significant backlog of vulnerabilities and improving how remediation is delivered at scale. The role also takes ownership of initiatives such as certificate lifecycle management and the effective use of security platforms including Privileged Access Management and Cloudflare. This is a hands-on position where success is measured by tangible improvements in security posture and operational resilience.

This role suits a senior infrastructure professional who enjoys working across multiple systems, solving practical security challenges, and taking ownership of outcomes. It offers the opportunity to work on high-impact issues with visibility across teams, making it well-suited to candidates looking to broaden their security exposure while remaining close to infrastructure.

Why should you apply?

Direct ownership of vulnerability remediation, with clear impact on reducing backlog and improving security outcomes
Opportunity to work on certificate lifecycle management, a high-demand and often underrepresented skillset
Hands-on role combining infrastructure and security, rather than a purely advisory or monitoring position
Broad exposure across enterprise systems, security tools, and cross-functional teams
Ability to influence how security is implemented and improved at scale, not just maintain existing processes

What skills and experience do I need to succeed?

8+ years of experience in enterprise systems administration or IT infrastructure
Strong generalist infrastructure background with the ability to work across multiple systems and environments
Hands-on experience with Windows Server (Active Directory, DNS, authentication, certificates) and working knowledge of Linux administration
Experience managing certificate lifecycle (TLS/PKI), including renewal and ongoing management (key priority)
Exposure to security tools such as Privileged Access Management (PAM) and Cloudflare (WAF/edge security)
Experience with logging/monitoring platforms (e.g., Splunk, Sumo Logic or similar)
Proven ability to remediate vulnerabilities hands-on, including patching and reducing backlog across systems
Strong scripting/automation skills (PowerShell required)
Ability to apply security controls across infrastructure and prevent misconfigurations

Experience automating certificate lifecycle processes across environments
Exposure to SIEM or centralized logging beyond administration, including tuning, alerting, or optimization
