Role Overview

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.

• 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.

• 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.

• Perform static and dynamic malware analysis to understand malicious file behavior 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.

• 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.

• 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.

• Prepare detailed incident investigation reports, including:
• Maintain accurate incident records, evidence, investigation notes, and supporting documentation.
• Contribute to the development and improvement of Incident Response playbooks, SOPs, investigation procedures, and escalation processes.
