Desirable

• As a Senior Threat Intelligence Researcher, you'll lead deep-dive investigations into both emerging & known threats, while maintaining a vigilant watch over malware developments to ensure defenses remain a step ahead of evolving attack methods
• You'll put into use your ability to synthesize complex data into actionable intelligence, and to provide senior management with the clear briefings necessary to understand and mitigate potential risks
• Furthermore, you'll be expected to develop refined hunting strategies (to adapt to and anticipate shifts in threat actor tactics & techniques), and to track adversary infrastructure, effectively counteracting shifts in threat actor tactics through detail-oriented investigation
• Drive External Threat Research: Triage and evaluate findings from OSINT and lead in-depth investigations into emerging threats. Systematically evaluate signals from the global OSINT community and dark web forums to determine their fidelity, relevance, and impact
• Synthesize Actionable Intelligence: Transform raw data from dark web forums, leak sites, and research repositories into high-level threat briefings and risk assessments for senior stakeholders
• Adversary Knowledge Management: Curate and expand our internal Knowledge Base and IOCs collections
• Track Actor Tradecraft (TTPs): Monitor adversary behaviors across the open and deep web to identify shifts in recruitment, target selection and shifting of operations
• Pivot Across Infrastructure: Identify and map threat actor footprints by pivoting through domain registrations, SSL certificates, passive DNS
• Bridge Intelligence Gaps: Collaborate closely with Detection Engineering to translate validated OSINT findings into durable hunting logic
• Develop OSINT Tooling: Build and automate scrapers, monitors, and data-visualization tools to identify anomalies and track threats in external telemetry
