IT Security Administrator

We are looking for a mid-level Security Administrator to join our small, close-knit IT team as its dedicated security expert. This is a hands-on role where you will own security across our Microsoft 365 environment, network perimeter, and endpoints - working directly alongside IT generalists rather than within a separate security function. You will need to be equally comfortable setting security direction and diving into the technical detail yourself., Microsoft 365 Security

• Maintain the email security platform and keep DLP policies and information protection controls current across M365 and other platforms.
• Conduct regular reviews of identity and access configurations in Entra ID, including Conditional Access, PIM, and MFA enforcement.

Network Security

• Configure and manage next-generation firewalls, VPNs, threat prevention profiles, and related controls.
• Ensure the perimeter stays hardened and properly integrated with the identity environment.

XDR & SIEM Platforms

• Own XDR and SIEM platforms end-to-end: deployment, policy configuration, analytic rule authoring, and alert tuning.
• Drive continuous improvement in detection coverage and response quality.

Incident Response

• Lead incident response across the full lifecycle: triage, containment, remediation, and post-incident review.
• Keep management informed throughout incidents with clear, non-technical communication on status and risk.

• Three to six years of relevant security or security-adjacent IT experience.
• Hands-on experience securing Microsoft 365 environments, including email security platforms, DLP and information protection policies, and Entra ID configuration (Conditional Access, PIM, MFA enforcement).
• Practical experience with EDR/XDR and SIEM platforms end-to-end: deployment, policy configuration, analytic rule authoring, and alert tuning. CrowdStrike or comparable platform experience required.
• Experience configuring and managing next-generation firewalls, VPNs, and threat prevention profiles. Palo Alto and Strata Cloud experience preferred.
• Ability to learn & lead incident response across the full lifecycle: triage, containment, remediation, and post-incident review - and to communicate status and risk clearly to non-technical stakeholders.
• Working knowledge of Windows and Linux endpoint hardening.
• Familiarity with Zero Trust and SASE architectures, and with GRC frameworks such as NIST CSF
• Understanding of information security principles relevant to financial institutions, including data protection, governance, and NCUA regulatory requirements.
• Bachelor's degree in Computer Science, Information Technology, Cybersecurity, or a related field - or equivalent hands-on experience.
• Relevant certifications such as CISSP, CISM, PCNSE, Security+, or GSEC are a plus.
• Self-directed, collaborative, and comfortable balancing competing priorities in a small IT team.
• Join us to be at the forefront of cybersecurity innovation!
