We are seeking a highly experienced and technically proficient Cybersecurity Manager to lead day‑to‑day security operations and ensure consistent execution of key cybersecurity initiatives. This role is best suited for a hands‑on leader with broad, real‑world experience across cybersecurity technologies and domains. The ideal candidate has a proven track record of running security operations, improving processes, and driving remediation efforts to completion.

This individual will bring structure, accountability, and follow‑through to the team while ensuring alignment with established cybersecurity frameworks such as NIST and CIS.

This role is responsible for the effective operation and continuous improvement of the organization’s cybersecurity program. The Cybersecurity Manager will oversee core security functions—including security monitoring, vulnerability management, identity and access management, endpoint protection, and network security—ensuring that tools and processes are not only in place, but functioning effectively and delivering meaningful results.

A key component of this role is ownership of Security Operations (Sec Ops). This includes ensuring effective monitoring, detection, and response capabilities across the environment through tools such as SIEM, EDR, and network‑based detection platforms.

This role also includes strengthening incident response practices, improving visibility across systems, and ensuring that security events are translated into actionable insights and continuous improvements to the organization’s security posture.

Another focus of the role is execution. This individual will take ownership of a prioritized body of work that includes vulnerability remediation, audit findings, and control improvements. Success in this role requires the ability to bring structure to ongoing efforts, ensure work is clearly defined, and drive initiatives through completion with measurable outcomes. The Cybersecurity Manager will be expected to identify where efforts are stalling and implement the discipline needed to maintain momentum and visibility.

In addition to operational leadership, this role will ensure that security practices are aligned with frameworks such as NIST and CIS in a practical and sustainable way. This includes translating framework requirements into real‑world controls, supporting audit activities, and ensuring that remediation efforts are both effective and lasting.

The role also includes oversight of cloud and application security practices. The Cybersecurity Manager will work closely with infrastructure and engineering…
