About the Role

The Incident Response (IR) Analyst is a hands-on technical responder within ISA Cybersecurity's Digital Forensics & Incident Response (DFIR) function, delivering the Security Incident Response (SIR) service across client engagements.

The successful candidate will have practical experience supporting incident response and forensic investigations, strong technical fundamentals across endpoint, network, and cloud environments, and the composure to work effectively under the pressure of active incidents.

Maintain chain-of-custody discipline suitable for legal proceedings throughout evidence handling.
Gather and analyze evidence from logs, email, endpoint artifacts, and other sources to identify indicators of compromise and attacker activity.
Reconstruct attack timelines from collected evidence to support root-cause analysis and scope determination.
Apply and help refine DFIR playbooks and runbooks in the course of live engagements, flagging gaps or improvements to the IR Commander.
Contribute to incident and digital evidence reports, including drafting technical findings for review by the IR Commander prior to client, legal, or law enforcement delivery.
Participate in post-incident reviews and lessons-learned sessions, translating findings into playbooks, tooling, or training improvements.
Assist with technical scoping input for proposals, Statements of Work (SOWs), and RFP responses as requested.
Correlate threat intelligence and observed TTPs into incident analysis, and feed findings back to detection and threat hunting teams.
Track and report on assigned incident metrics and contribute to continuous-improvement initiatives for the DFIR practice.
Support the IR readiness program, including IR Plan engagements, Tabletop Exercises (TTX), and playbook validation.
Act as a client-facing technical resource during engagements under the direction of the IR Commander.
Collaborate with SOC analysts and Service Owners to keep incident response work aligned with detection capabilities.
