• Lead end-to-end incident response — detection through containment, eradication, recovery, and post-incident improvement — including root-cause analysis and corrective action tracking.

• Build, tune, and maintain detection logic across SIEM, EDR, cloud, and network platforms; conduct proactive threat hunting aligned to MITRE ATT&CK.

• Develop and maintain SecOps tooling, scripts, API integrations, and workflow automations to improve investigation speed and response execution.

• Apply AI responsibly in SecOps workflows, with the ability to explain, validate, test, and maintain all AI-assisted outputs.

• Collaborate cross-functionally to close telemetry gaps, improve detection coverage, and translate incident findings into lasting security improvements.

Required Qualifications

• Hands-onknowledgein security operations, incident response, detection engineering, or threat hunting, with demonstrated ability to lead significant investigations.

• Strong knowledge of attacker tactics and techniques across endpoint, identity, network, cloud, and email environments, including MITRE ATT&CK mapping and IOC analysis.

• Experience with SIEM platforms (Sentinel, Splunk, Chronicle, QRadar, or Elastic) and proficiency writing and tuning detection queries using KQL, SPL, Sigma, YARA, or equivalent.

• Experience with EDR/XDR platforms (Defender for Endpoint, CrowdStrike, SentinelOne, Cortex XDR, or Carbon Black), including triage, investigation, and containment.

• Scripting or automation experience using Python, PowerShell, or Bash; AI-assisted development acceptable provided the candidate can explain, validate, test, and maintain the code.

• Practical use of AI tooling for security — such as Claude, GitHub Copilot, or OpenAI Codex — to accelerate tooling development, detection drafting, and analysis workflows.

• Experience with at least one cloud platform (AWS, Azure, GCP, or OCI), including cloud logging, identity, and security monitoring.

• Solid understanding of identity security, including MFA, conditional access, privileged access, token abuse, and identity-based attacks.

• Strong communication skills with the ability to explain complex security issues to technical and non-technical audiences.

• Independent, self-starter, analytical, evidence-driven work style with strong attention to detail.

Preferred Qualifications

• Bachelor’s degree in Cybersecurity, Information Assurance, Computer Science, or a related field.

• Experience with threat intelligence, malware triage, digital forensics, or reverse engineering.

• Experience with vulnerability management or compliance-driven SecOps (SOC 2, ISO 27001, PCI DSS, or HIPAA).

• Familiarity with detection-as-code, Git-based workflows, CI/CD pipelines, and code review practices.

• Relevant certifications such as GIAC (GCFA, GCIH, GCFR, GCLD, GDAT, or GEIR), OffSec (OSIR, OSTH, OSCP, or OSAI), AWS Security Specialty, Google Professional Cloud Security Engineer, Microsoft SC-200, or CompTIA CASP+.

• Equivalent combination of education, training, and relevant professional experience accepted in lieu of a formal degree.
