We are looking for an experienced Cybersecurity Incident Response Specialist with 8–10 years of hands-on cybersecurity experience to manage and investigate security incidents across enterprise environments.
The candidate will be responsible for end-to-end ownership of cybersecurity incidents, including triage, investigation, containment, eradication, recovery, Root Cause Analysis (RCA), malware analysis, and digital forensic analysis. The role also requires strong customer-facing skills to lead incident discussions, provide regular updates, explain technical findings, and present investigation outcomes and recommendations.

Key Responsibilities

Incident Response & Investigation
•    Take end-to-end ownership of cybersecurity incidents from initial detection through closure.
•    Lead investigation of Critical, High, and complex security incidents and coordinate response activities across relevant teams.
•    Perform incident triage, scoping, containment, eradication, recovery, and post-incident analysis.
•   Investigate incidents involving ransomware, malware, phishing, account compromise, credential theft, data exfiltration, insider threats, web attacks, lateral movement, privilege escalation, and other advanced threats.
•    Analyze security alerts and correlate information across EDR, SIEM, network, identity, cloud, email, and other security technologies.
•    Develop incident timelines and determine the attack vector, affected assets, compromised accounts, attacker activity, persistence mechanisms, and overall impact.
•    Identify Indicators of Compromise (IOCs), attacker Tactics, Techniques, and Procedures (TTPs), and map findings to the MITRE ATT&CK framework.
•  Coordinate with SOC, Threat Hunting, Threat Intelligence, IT, Cloud, Network, IAM, Application, Legal, and other stakeholders during major incidents.
Root Cause Analysis (RCA)
•    Perform detailed Root Cause Analysis for security incidents.
•  Determine the initial attack vector, contributing factors, security/control gaps, and reasons existing preventive or detective controls did not stop or detect the activity earlier.
•    Conduct post-incident reviews and lessons-learned sessions.
•    Develop clear corrective and preventive actions based on investigation findings.
•    Track remediation recommendations with relevant stakeholders through closure.
•    Prepare comprehensive RCA reports suitable for technical teams, management, and customers.
Malware Analysis
•    Perform static and dynamic malware analysis to understand malicious file behaviour and capabilities.
•    Analyze suspicious executables, scripts, PowerShell commands, documents, URLs, and other artifacts.
•  Identify malware persistence mechanisms, command-and-control activity, network indicators, file-system changes, registry modifications, and related behaviors.
•    Extract IOCs and behavioral indicators for threat hunting and detection engineering.
•    Perform malware sandboxing and behavioral analysis where required.
•    Provide recommendations for detection, containment, and prevention based on malware-analysis findings.
Digital Forensics
•    Perform digital forensic investigations on endpoints and other relevant systems.
•  Analyze Windows/Linux artifacts, event logs, file systems, registry artifacts, browser artifacts, authentication logs, memory artifacts, and other forensic evidence.
•    Perform disk and memory analysis where required.
•    Collect and preserve digital evidence following appropriate forensic procedures and chain-of-custody requirements.
•    Build forensic timelines and reconstruct attacker activities.
•    Determine the scope and impact of compromise using forensic evidence.
•    Document forensic findings clearly and maintain investigation evidence appropriately.
Customer & Stakeholder Management
•    Act as a key technical point of contact for customers during cybersecurity incidents.
•    Lead incident calls and communicate investigation progress, impact, containment status, risks, and next steps.
•    Provide timely and accurate incident updates to customers and internal leadership.
•    Translate complex technical investigation findings into clear business-level communication.
•    Manage customer expectations during high-severity and time-sensitive incidents.
•    Present RCA and forensic investigation findings to customers and senior stakeholders.
•    Handle technical questions and confidently explain investigation methodology, evidence, conclusions, and recommendations.
•    Coordinate with multiple internal and customer teams to drive incidents toward timely resolution.
Incident Reporting & Documentation
•    Prepare detailed incident investigation reports, including: 
o    Executive summary
o    Incident timeline
o    Scope and impact
o    Root cause
o    Attack vector
o    IOCs and TTPs
o    Investigation findings
o    Containment and remediation actions
o    Control gaps
o    Corrective and preventive recommendations
o    Lessons learned
•    Maintain accurate incident records, evidence, investigation notes, and supporting documentation.
