• Build and tune detections using Elastic and Datadog.
• Conduct proactive threat hunting based on threat intelligence and attacker TTPs.
• Translate threat intelligence into actionable detections, IOCs, and response capabilities.
• Improve security visibility and telemetry across our AWS and blockchain infrastructure.
• Develop automation for alert enrichment, investigation, and incident response.
• Perform root-cause analysis and drive remediation following security incidents.
• Work closely with Engineering, DevOps, Platform, and Security teams to strengthen our overall security posture.

Desired Candidate Profile:

• 5–7 years of experience in Security Operations, Detection Engineering, Incident Response, Threat Hunting, or Security Engineering.
• Strong hands-on experience with SIEM, security monitoring, and log analysis.
• Experience with Elastic / Elasticsearch / Kibana and Datadog.
• Strong understanding of Incident Response and MITRE ATT&CK.
• Experience building and tuning security detections.
• Good understanding of AWS, Linux, networking, and cloud security.
• Strong scripting/automation skills in Python, Bash, or similar.
• Strong analytical and investigative mindset with the ability to independently handle security incidents.

Good to Have:

• Experience with Web3, blockchain, cryptocurrency, or digital asset security.
• Experience with AWS security services such as CloudTrail, GuardDuty, Security Hub, and VPC Flow Logs.
• Experience with threat hunting, SOAR, EDR/XDR, Sigma, YARA, or Suricata.
• Security certifications such as GCIH, GCIA, GCFA, Security+, CySA+, or equivalent.
