Senior Advanced Cybersecurity Detection & Threat Intelligence Engineer

Key Responsibilities

• Design, implement, and continuously tune threat detections across SIEM, EDR/XDR, OT security platforms, and cloud-native security tooling.

• Own the end-to-end detection engineering lifecycle — hypothesis development, rule authoring, validation, deployment, tuning, and retirement — aligned to MITRE ATT&CK across IT, OT, cloud, and identity environments.

• Operationalize threat intelligence by translating finished intel, IOCs, and adversary TTPs into actionable detection rules, hunt hypotheses, and automated enrichment workflows.

• Manage and maintain threat intelligence feeds and platforms, including ingestion, validation, confidence scoring, and expiration of IOC libraries.

• Build, maintain, and improve SOAR automation playbooks, enrichment pipelines, and detection workflows to increase alert fidelity and reduce analyst toil.

• Develop and maintain detection content for OT/ICS environments, including industrial protocol anomaly detection, Purdue model segmentation visibility, and OT-specific threat actor TTPs.

• Improve security telemetry quality and coverage by collaborating with infrastructure, network, cloud, OT, and platform engineering teams to onboard new log sources and validate data fidelity.

Required Skills & Experience

• Must reside in India — this role is approved for India-based candidates only. 

• 7–10+ years of experience in cybersecurity with a focus on detection engineering, security operations, or threat intelligence.

• Strong hands-on experience with SIEM platforms such as Microsoft Sentinel, Splunk, Elastic, or QRadar — including rule authoring, query development, and data onboarding. 

• Deep understanding of adversary tactics, techniques, and procedures with applied experience mapping detections to MITRE ATT&CK.

• Hands-on experience developing detection rules, correlation logic, behavioral analytics, and threshold-based alerting across multiple telemetry sources. 

• Demonstrated experience with SOAR platforms for building automated enrichment pipelines, detection workflows, and threat intel operationalization.

• Strong scripting and automation skills in Python, PowerShell, or KQL for detection development, data parsing, and workflow automation.

• Experience with threat intelligence platforms (TIP) for IOC lifecycle management, feed integration, and intel-to-detection operationalization. 
   

Preferred Qualifications 

• Experience building or maturing a detection engineering program including detection backlog management, coverage gap analysis, and ATT&CK heatmap maintenance. 

• Experience with OT/ICS security monitoring. 

• Familiarity with threat intelligence integration and threat hunting methodologies. 

• Familiarity with detection-as-code practices, version control for detection content, and automated rule testing pipelines. 

• Knowledge of cloud-native security monitoring and identity telemetry. 

• Relevant certifications such as GDAT, GCDE, GCIA, GCED, or equivalent credentials.
