About The Position

We are seeking an Information Security Analyst to support enterprise threat investigations, vulnerability remediation coordination, and security control improvements across a large distributed environment. This role combines incident response support, exception handling, documentation ownership, and cross-team collaboration with infrastructure and development groups. This is not a queue-based SOC monitoring role and not a compliance-only position. It is a hands-on enterprise security operations role suited for someone with broad exposure across multiple security domains who can operate independently and adapt in environments where documentation may still be evolving.

Requirements

3+ years of hands-on information security experience across multiple security disciplines
5+ years of broader IT, infrastructure, or security operations experience
Experience investigating alerts across SIEM, endpoint, identity, or network telemetry platforms
Experience working in large enterprise or distributed environments
Ability to collaborate effectively across infrastructure, development, and security teams
Strong written communication skills, including the ability to produce SOPs and investigation documentation
Comfort operating in environments where processes are evolving rather than fully predefined
Strong networking fundamentals (TCP/IP)
Working knowledge of Windows server and desktop environments
Experience supporting vulnerability remediation programs

Nice To Haves

Exposure to SIEM platforms such as Splunk, QRadar, Securonix, Elastic, or similar
Experience with EDR/XDR platforms such as CrowdStrike, SentinelOne, Sophos XDR, or Carbon Black
Familiarity with identity platforms such as Active Directory, Okta, or SSO environments
Azure security exposure
IDS/IPS monitoring experience
Exposure to NIST, ISO 27001, or CIS frameworks
Linux familiarity
Certifications such as CISSP, CEH, Security+, or similar

Responsibilities

Investigate phishing activity, malware alerts, authentication anomalies, and IDS/IPS events
Correlate activity across SIEM, endpoint, identity, and network telemetry sources
Respond to security alerts and coordinate escalation with infrastructure and development teams
Evaluate software allow/deny requests based on security risk and operational impact
Review website filtering requests and make practical risk-informed access decisions
Support vulnerability tracking and remediation coordination across infrastructure and Azure environments
Recommend improvements that strengthen enterprise security controls and reduce exposure
Build working relationships with server teams, development teams, and global security contacts
Contribute to SOP development and improve investigation documentation where processes are still maturing
Support enterprise security posture initiatives aligned with long-term roadmap priorities
