Conduct independent digital forensic investigations across host and disk, memory, network, cloud, and identity environments while maintaining rigorous evidence-handling practices. - Investigate security events using EDR and SIEM telemetry, developing queries, correlation logic, and incident timelines from available log data. - Participate in the incident response on-call rotation and exercise defined containment authority, including host isolation and session revocation when appropriate. - Develop, update, and improve incident response playbooks based on lessons learned from real incidents. - Lead post-incident reviews and ensure identified findings and corrective actions are tracked through completion. - Automate repetitive triage and evidence-collection activities and use AI-assisted workflows to improve investigation efficiency while applying sound judgment around sensitive information. - Produce clear and defensible incident documentation for both technical and executive audiences, translating detailed findings into concise business-level summaries. - Apply threat intelligence and MITRE ATT&CK techniques to active investigations and use investigative findings to strengthen detection and response capabilities. - Contribute to the ongoing maturity of the incident response program, including improvements to processes, tooling, automation, and operational readiness. **Requirements:** - 6–8 years of hands-on cybersecurity experience, with the majority focused on incident response and/or digital forensics. - Demonstrated ownership of the complete incident response lifecycle, from detection validation through post-incident review. - Hands-on digital forensics experience spanning host and disk, memory, network, cloud, and identity investigations. - Strong experience with EDR/EPP platforms, including endpoint telemetry investigation, response actions, and tuning detection or response capabilities. - Strong SIEM experience, including query development, correlation logic, and reconstruction of incident timelines from log data. - Practical experience with forensic tools such as Velociraptor, KAPE, Volatility, Autopsy, EnCase, FTK, X-Ways, plaso, Zeek, or Wireshark. - Strong evidence-handling discipline, including chain of custody, sound acquisition practices, and documentation suitable for legal, regulatory, and client review. -

Excellent technical and executive communication skills, with the ability to produce both detailed incident timelines and concise executive summaries. - Willingness to participate in a shared incident response on-call rotation. - Experience with CrowdStrike Falcon EDR, Falcon Next-Gen SIEM, or similar platforms is preferred. - Experience with AWS incident response, including CloudTrail, GuardDuty, IAM abuse patterns, and related cloud security investigations is preferred. - Experience investigating identity-related threats, particularly within Okta environments, including session hijacking, MFA fatigue, token theft, and SSO abuse. - Healthcare, fintech, or other regulated-industry experience involving sensitive data is advantageous. - Familiarity with HIPAA, HITRUST, or SOC 2 from an operational perspective, including breach determination processes, is preferred. - Relevant certifications such as GCFA, GCFE, GCIH, GNFA, GCIA, GREM, or equivalent demonstrated expertise are valued. - Experience with malware triage, reverse engineering fundamentals, SOAR platforms, AI-assisted incident response workflows, threat intelligence, or IR program maturity is beneficial. - Ability to work effectively in a collaborative environment while maintaining strong independent judgment and accountability. **Benefits:** -
