**Position Is Contingent Upon Award**
Peraton Labs is hiring a Senior Incident Response Analyst to lead hands-on incident response for the Covered California and CalHEERS environments, own detection engineering and threat hunting, and serve as backup incident manager in coordination with the client's Information Security Officer and our Security Services Manager. You will carry the primary on-call rotation.
You will work with Covered California security leadership, infrastructure and application teams, our on-site security engineering and GRC colleagues, and an on-call digital forensics examiner. The goal is that incidents in a system holding the PII, PHI, and federal tax information of millions of Californians are detected early, contained fast, reported inside contractual and regulatory deadlines, and genuinely learned from.
What You Will Do In This Role:
• Lead incident response end to end. Own triage, containment, eradication, recovery, and post-incident review, and serve as backup incident manager in coordination with the client Information Security Officer and the Security Services Manager.
• Build and exercise the playbooks. Develop and maintain incident response playbooks and runbooks, and exercise them through tabletop and functional drills.
• Own detection and monitoring. Drive SIEM and SOAR content development, log source onboarding, alert tuning, and detection engineering across cloud and on-premises telemetry.
• Hunt proactively. Conduct threat hunting mapped to MITRE ATT&CK, and turn hunt findings into durable detections.
• Run defensible investigations. Coordinate evidence handling and chain of custody, communications, escalation, and reporting; produce post-incident reports and lessons-learned; engage the digital forensics examiner when a matter requires formal forensic examination or evidence for legal, HR, or privacy proceedings.
• Meet the contract's clock. Build and operate response procedures that satisfy the engagement's tight notification obligations, including notification within one hour when personnel no longer require system access, and the Privacy Addendum's breach-reporting timelines.
• Report to leadership and support adjacent work. Provide incident status and escalation reporting to security leadership on defined timelines, and support vulnerability management and logging and monitoring coordination.
