• Lead high-severity investigations across endpoint, identity, email, network, cloud, and SaaS telemetry; build and defend a timeline and root cause, not just a list of alerts.
• Make and execute containment decisions: session revocation, credential resets, token invalidation, host isolation, mailbox rule removal, conditional access changes, and network blocks - weighing business impact against risk.
• Run eradication and recovery, verify the adversary is actually out, and confirm persistence mechanisms (OAuth grants, inbox rules, MFA device registrations, scheduled tasks, service principals) are removed.
• Perform log analysis and light forensics (memory, disk, M365/Entra audit logs, proxy/firewall/VPN logs) and preserve evidence to a standard that survives legal and regulatory review.

PHI/PII and data security incidents

• Lead investigations involving protected health information (PHI) and personally identifiable information (PII): unauthorized access, misdirected or exposed data, insider misuse, lost or compromised devices, and third-party or vendor exposures.
• Determine what data was involved, who had access, for how long, and whether it was actually viewed or exfiltrated - and document that determination to a standard that supports HIPAA breach risk assessments and regulatory response.
• Work directly with Privacy, Compliance, and Legal to feed incident facts into breach determination and notification decisions, and coordinate takedown or remediation of exposed data (public sites, file-sharing platforms, misconfigured storage, email).
• Contribute to data protection controls (DLP, access reviews, data classification, secure file-transfer) based on what incidents reveal.

Communication

• Own incident communications: concise, accurate status updates to the CISO and security leadership, plain-language briefings to business owners, and clear handoffs to IT, Legal, Privacy, and HR.
• Write incident reports and post-incident reviews that a non-technical executive can read and that an engineer can act on.
• Coordinate with external parties as needed: MDR/MSSP, forensic retainers, cyber insurance, vendors, and third-party partners involved in an incident.

Detection and improvement

• Tune and build SIEM detections and response playbooks from what you learn in incidents; measure and reduce false positives, dwell time, and time to contain.
• Threat hunt proactively using current intelligence, and convert findings into detections or hardening recommendations.
• Identify control gaps (offboarding, SSO/MFA coverage, mail-flow protections, privileged access) and drive them to closure with the owning teams.

Team leverage

• Serve as escalation point and mentor for L1/L2 analysts; review their investigations and raise the quality bar.
• Maintain and improve runbooks, severity definitions, and escalation criteria.
• Participate in the on-call rotation and lead tabletop exercises.

• 5+ years in security operations or incident response, with at least 2 years leading investigations independently on high-severity incidents.
• Deep, practical expertise in:
• SIEM / detection engineering - query languages (KQL, SPL, or equivalent), correlation logic, detection tuning, log source onboarding (e.g., Microsoft Sentinel, Rapid7 InsightIDR, Splunk).
• Identity and access - Microsoft Entra ID / Active Directory, Conditional Access, MFA, OAuth/consent grants, token and session abuse, privileged access, offboarding controls.
• Email security - BEC and phishing investigation, header/URL/attachment analysis, mail-flow rules, DMARC/DKIM/SPF, secure email gateway and API-based email security tools.
• Endpoint - EDR investigation and response (Defender for Endpoint, CrowdStrike, or similar), persistence and lateral movement techniques.
• Network security - firewall, proxy, VPN, and DNS log analysis; understanding of segmentation, C2 patterns, and data exfiltration indicators.
• Fluency with MITRE ATT&CK and the ability to map observed activity to it.
• Strong written communication: you can write an executive status update and a technical timeline in the same hour, and both are clear.
• Judgment: you know when to contain immediately, when to watch, and when to escalate, and you can explain why.
• Experience investigating incidents involving PHI/PII or other regulated data, including scoping data exposure and supporting breach risk assessments.

Preferred

• Healthcare industry experience and working knowledge of HIPAA Privacy/Security Rules, breach notification requirements, and state privacy laws.
• Cloud incident response experience (Azure, M365, AWS, or GCP) including SaaS/OAuth-based compromises.
• Scripting for investigation and automation (PowerShell, Python, KQL).
• Experience with SOAR platforms and automating response actions.
• Certifications such as GCIH, GCFA, GCIA, CISSP, or Microsoft SC-200.
• Experience handling incidents involving third parties, vendors, or divested/carved-out business units with shared infrastructure.
