Position Overview:

Apollo’s SOC Analyst I is a member of the Security Operations Center team responsible for monitoring and detecting threats and cybersecurity attacks across our clients’ networks and systems. The SOC Analyst I monitors, analyzes, and responds to security events and alerts, working collaboratively with the team to protect client digital assets and maintain a strong security posture.

Key Responsibilities:

  • Monitor security events and alerts using SIEM tools and other security technologies.

  • Analyze and triage security alerts to determine severity and potential impact.

  • Perform initial incident response activities and escalate issues when necessary.

  • Document and track security incidents and their resolutions.

  • Assist in creating and maintaining security documentation and procedures.

  • Contribute to the development and improvement of security metrics and reporting.

  • Collaborate with other team members and departments to address security concerns.

  • Partner with SOC Analyst II to develop and refine SIEM correlation rules.

  • Stay informed about emerging threats and security trends.

Qualifications

  • Required

    • Basic understanding of networking concepts, protocols, and security principles.

    • Familiarity with common security tools and technologies (e.g., firewalls, IDS/IPS, SIEM).

    • Strong analytical and problem-solving skills.

    • Excellent written and verbal communication skills.

    • Ability to work in a fast-paced environment and handle multiple priorities.

    • Basic scripting or programming skills (e.g., Python, PowerShell).

    • Ability to work in shifts, including swings, nights, weekends, and holidays.

  • Preferred

    • Experience with CrowdStrike, Sophos, and/or SentinelOne platforms.

    • Familiarity with one or more SIEM platforms (e.g., Stellar, Splunk, Exabeam, LogRhythm, Elastic).

    • Experience with cloud security concepts and technologies.

    • Experience with threat intelligence platforms and processes.

    • Familiarity with the MITRE ATT&CK framework.

    • Familiarity with network infrastructure and security concepts (firewalls, VPNs, network segmentation, IDS/IPS).

    • Experience with enterprise firewall platforms (e.g., Sophos, Fortinet, Cisco, Check Point).

Expectations:

  • At 30 days:

    • Complete onboarding to Apollo's SOC tool stack

    • Shadow senior analysts across monitoring shifts to internalize Apollo's alert triage logic, escalation thresholds, severity classifications, and incident documentation standards before owning work independently

    • Begin monitoring and triaging low-complexity alerts under guidance

  • Within 90 days:

    • Monitor and triage security alerts independently during assigned shifts — assessing severity, performing initial incident response activities, and escalating appropriately without needing to be prompted

    • Produce clean, accurate incident documentation consistently — every event tracked, every resolution recorded, in a format that's useful to the next analyst who picks it up

    • Demonstrate growing familiarity with the MITRE ATT&CK framework — able to map common alert types to relevant tactics and techniques and apply that context to triage decisions

    • Participating in shift handoffs, flagging emerging patterns to Analyst IIs, and raising questions that improve the team's collective awareness

  • By 180 days:

    • Carry a full monitoring workload independently across assigned shifts with sound, consistent triage judgment — escalations are timely, severity calls are accurate, and false positive handling is efficient

    • Partner actively with SOC Analyst IIs on SIEM correlation rule development — contributing observations from day-to-day monitoring that inform rule refinement and detection improvement

    • Draft or meaningfully improve at least one SOC procedure document, runbook, or triage playbook that gets adopted by the team

    • Demonstrate working proficiency with at least one SIEM platform beyond basic alert consumption
