PLEASE NOTE these positions are expected to become available in Winter/Spring 2027. Recruiters will contact qualified applicants as timeline firms up.

Primary Responsibilities

Threat Hunting

• Develop and execute hypothesis-driven hunt campaigns based on adversary TTPs
• Query and correlate telemetry across cloud, identity, and network infrastructure to surface "low and slow" attacks
• Partner with detection engineering to convert hunt findings into automated SIEM/EDR detection rules
• Build automation for countermeasure deployment and asset isolation
• Use MITRE ATT&CK to proactively search for APT activity

Threat Intelligence

• Produce strategic, operational, and tactical intelligence reports on emerging threats and actor motivations
• Characterize adversary TTPs and build APT profiles using MITRE ATT&CK
• Manage the intelligence lifecycle: PIRs, collection plans, and dissemination

• Deliver Indications & Warnings (I&W) to support hunt and DCO operations

Cyber Fusion

• Synthesize external threat intelligence with internal hunt telemetry into a unified operational picture
• Author Fusion Reports blending forensics and strategic intelligence for leadership
• Correlate global threat activity against internal sensor logs via SIEM/TIP
• Pair vulnerability data with active threat reporting to prioritize remediation
• Maintain the team's "single source of truth" for prioritized threat data

Shared across all tracks

• Maintain situational awareness of the evolving threat landscape and its relevance to the customer enterprise
• Author clear technical reporting and metrics on findings, gaps, and posture improvements
• Collaborate across Hunt, Intel, Engineering, and Fusion functions to ensure intelligence drives defensive action

Preferred Skills

• Query languages: SPL (Splunk), KQL (Kusto), or Elastic DSL for large-scale data analysis
• Scripting: Python, PowerShell, or Bash for automation and data enrichment
• Cloud familiarity: AWS, Azure, O365, containerized workloads
• Framework fluency: MITRE ATT&CK, Cyber Kill Chain, Diamond Model of Intrusion Analysis
• DFIR experience (packet capture / endpoint log analysis, root-cause reconstruction)
• Experience with Threat Intelligence Platforms (Anomali, ThreatConnect, MISP) or OSINT/commercial threat portals (Recorded Future, VirusTotal, Mandiant Advantage)
