The SecOps Analyst provides on-site, 24/7/365 Tier 1 security monitoring, event analysis, and incident triage for Google Public Sector’s (GPS) sovereign, classified, and controlled environments. Initial support covers Google Distributed Cloud (GDC) Air-Gapped security fabrics and Controlled Unclassified Information (CUI) domains, with scope designed to scale across current and future Google sovereign infrastructure, appliances, and air-gapped offerings. The analyst monitors SIEM/EDR alerts, enriches and correlates events for high-confidence triage, and retains end-to-end alert ownership, customer communication, and incident documentation in coordination with SecOps Managers and Google SecOps engineering.

Responsibilities

• Monitor GDC Air-Gapped security fabrics and CUI domains using Google Managed SecOps tools; analyze events in Splunk, ELK, designated SIEM systems, and EDR tools.
• Provide initial GPS customer and incident-reporting support via email and support portals. Acknowledge alerts within 5 minutes of creation; deliver a First Meaningful Response (FMR) within 15 minutes for High/Critical alerts and 25 minutes for all others.
• Collect and analyze event descriptions, affected-system details, security telemetry, and related evidence. Assess severity and operational impact and correlate events for high-confidence triage. Develop evidence-based disposition recommendations and escalate confirmed threats to the appropriate Google SecOps representative in accordance with established procedures and runbooks.
• Own and actively manage ServiceNow incidents and investigations, including analysis, customer updates, follow-on actions, and required government incident-report drafts. Transfer ownership only with explicit Google manager approval; coordinate incident response and required EDR tooling with Google SecOps.
• Before Google on-call consults, evaluate observed activity, results of playbooks and investigative queries, IOCs, and supporting technical evidence to develop a proposed incident disposition and recommended next steps. For active High/Critical shift handoffs, document current status, analysis completed, analytical findings, and recommended next steps; immediately accept incoming incidents without rejection.
• Provide hands-on-keyboard accreditation support to demonstrate and validate playbooks, runbooks, IT infrastructure, and Data Center operations. Evaluate alert effectiveness and playbook performance, identify detection or workflow gaps, and develop tuning and process improvement recommendations.
• Support continuous coverage during holidays and severe or inclement weather; coordinate with teammates to keep at least one FTE in each occupied SecOps room. Answer and route SecOps calls, seek on-call guidance as needed, and respond to SecOps virtual communications within 15 minutes.
• When designated live Queue Manager, monitor alert timers and intervene at least 5 minutes before response targets expire. As designated senior analyst, pre-screen off-hours consults for next-business-day Manager review.
• Participate in requested customer situational awareness calls; assess reported information for security and operational significance, identify potential impacts requiring further investigation or response, and communicate relevant findings and tasking through designated channels using appropriate unclassified working when required.
• Maintain records and supply weekly activity report inputs: alert response SLA compliance, triage dispositions, playbooks validated/updated, noisy alerts and tuning recommendations, work-item quality flag trends, and shift staffing.
• Other duties as assigned.

Qualifications

• 3+ years of experience in security operations (SOC), cybersecurity, or systems administration.
  • Hands-on experience with SIEM, IDS, EDR, and case management or ticketing tools.
  • Technical experience supporting Windows and Linux operating systems, networking infrastructure, scripting, and security application troubleshooting.
• Possess and maintain an active DoD 8140 Cyber Defense Analyst (CSSP Analyst) role-qualifying certification (e.g. CySA+, GCIA, GCIH, CEH, or CISSP).
• Successfully complete Google’s extended workforce onboarding process and maintain required government-contract compliance, including mandatory training.
• Active TS/SCI with Full Scope Polygraph
• Successfully pass background and drug screening

Preferred Qualifications:

• Bachelor’s degree in cybersecurity or computer science, or equivalent practical experience.
• Experience in a dedicated SOC, including event analysis using Splunk, ELK, or other SIEM systems.
• Hands-on security detection development and alert tuning in partnership with Tier 2 and Tier 3 engineering teams.
• Experience compiling threat reports that translate complex indicators of compromise (IOCs) into narrative overviews.
• Advanced understanding of LAN/WAN topologies, Google Cloud Platform, Kubernetes, and air-gapped computing environments.
• Experience operating in classified SCIF environments, handling sensitive or classified data, or supporting cloud environments.
• Elastic Certified SIEM Analyst or Splunk Core Certified User certification.

Knowledge, Skills and Abilities:

• General knowledge of network analysis, vulnerability scanning (e.g., Nessus), security hardening best practices (e.g., DISA STIG), and vulnerability landscapes (e.g., OWASP Top 10).
• Foundational understanding of LAN/WAN topologies, Kubernetes, and air-gapped computing environments.
• Clear written and verbal communication with customers, teammates, and engineering teams; ability to translate technical findings into concise updates, diagnostic summaries, and incident reports.
• Ability to collaborate in classified, mission-critical environments, protect sensitive information, and follow security procedures, approved runbooks, and escalation protocols.
• Disciplined documentation and time management; ability to maintain accurate incident and shift records, prioritize alerts by severity, meet response timelines, and adapt to changing mission needs.
• Strong analytical and investigative skills to interpret SIEM/EDR alerts, correlate events and security telemetry, identify indicators of compromise, assess severity and operational impact, develop evidence-based incident dispositions, and exercise sound judgment in recommending response actions or escalation.
• Ability to retain incident ownership during technical consults, track follow-on actions, and maintain customer updates in coordination with SecOps Managers and Google SecOps.
• Ability to evaluate detection effectiveness and investigative workflows, identify noisy alerts and playbook gaps, and develop practical recommendations for alert tuning, playbook improvement, and operational process enhancement.
