About the Job

Requirements

  • 2–4+ years of hands-on experience in a security operations center or security operations role with direct alert triage responsibility.
  • Solid understanding of the MITRE ATT&CK framework and ability to use it to label and communicate attacker behavior.
  • Working knowledge of endpoint detection and response tooling, including process tree analysis, behavioral detection review, and basic endpoint artifact interpretation.
  • Familiarity with security information and event management investigations, including querying logs, correlating events across sources, and building timelines from normalized data.
  • Understanding of foundational network protocols, including TCP/IP, DNS, HTTP/S, and TLS, and how attackers abuse them.
  • Exposure to cloud security monitoring, such as AWS or GCP, including audit log review and IAM-related alert investigation.
  • Experience investigating identity-based alerts in an enterprise identity provider such as Okta, Entra ID, or equivalent.
  • Strong written communication skills for producing accurate, structured, useful case notes.

Responsibilities

  • Monitor and triage alerts across endpoint, network, cloud, runtime, and identity data sources with accuracy and appropriate urgency.
  • Perform structured investigations on escalated or ambiguous alerts by pivoting across log sources, correlating events, and building a coherent timeline.
  • Classify alerts as true positive, false positive, or benign, and document the rationale for the classification.
  • Identify the scope and blast radius of confirmed incidents, including affected users, systems, and data, before escalating or containing them.
  • Escalate cases to senior analysts with a complete investigation package containing context, evidence, a timeline, and a hypothesis.
  • Participate in active incident response under senior analyst or manager direction by collecting evidence, pulling logs, and reconstructing timelines.
  • Execute directed containment actions, including endpoint isolation, account suspension, and token revocation, with documented rationale.
  • Maintain accurate and timely case documentation throughout the incident lifecycle.
  • Contribute to post-incident timelines and assist with root cause documentation.
  • Monitor cloud audit logs and native threat detection findings for suspicious IAM activity, unusual API calls, and access anomalies.
  • Investigate identity provider events, including suspicious logins, MFA bypass attempts, session anomalies, and unauthorized app assignments.
  • Recognize common cloud-native attack patterns, including credential abuse via metadata service, privilege escalation via IAM role assumption, and storage misconfiguration access.
  • Correlate cloud-side events with endpoint and network telemetry to build a fuller picture of attacker activity.
  • Flag false positives and noisy detections with enough context for a senior analyst or detection engineer to tune them.
  • Identify gaps in existing detection coverage based on observed alert patterns during triage.
  • Apply knowledge of MITRE ATT&CK to label attacker techniques and communicate findings consistently.
  • Contribute to runbook accuracy by flagging outdated steps or missing guidance encountered during investigations.
  • Work with detection engineers to build detections and contribute to automation with an engineering mindset.
  • Write clear, concise case notes that allow a colleague to continue an investigation without repeating prior work.
  • Produce shift handoff summaries that accurately represent open cases, pending actions, and investigation status.
  • Communicate incident updates to the Security Operations Manager clearly enough to support upward briefings without re-investigation.

Desired Qualifications

  • Experience with next-generation endpoint detection and response platforms such as CrowdStrike Falcon or SentinelOne beyond basic alert review, including RTR, process trees, and custom detections.
  • Hands-on experience with a cloud-native security information and event management platform such as Google SecOps/Chronicle or Microsoft Sentinel.
  • Exposure to cloud security posture management or cloud security tooling such as Wiz or Prisma Cloud as an investigation data source.
  • Familiarity with AWS incident response fundamentals, including CloudTrail, GuardDuty, VPC Flow Logs, and IAM chain analysis.
  • Understanding of encoding, encryption, and hashing and their relevance to attacker obfuscation techniques.
  • Experience working alongside or receiving escalations from a managed detection and response partner.
  • Relevant certifications such as CompTIA CySA+, Security+, BTL1, GCIH, or an equivalent practical security credential.
