Staff Threat Researcher

Summary

Join SentinelOne as a Staff Threat (Intelligence) Researcher and lead threat intelligence initiatives, performing in-depth technical threat analysis, developing detection logic, and designing threat hunting strategies. You will curate a threat intelligence knowledge base, monitor adversary infrastructure, collaborate with detection engineers, and produce intelligence reports. The role requires expertise in malware analysis, endpoint security, operating system internals, and cloud security. Strong data analysis and scripting skills are essential. SentinelOne offers a competitive benefits package including stock and bonuses, flexible time off, insurance and health benefits, work perks, and growth opportunities.

Requirements

• Expertise in malware analysis (both static and dynamic), reverse engineering, unpacking, and deobfuscation using tools like IDA Pro, Ghidra, x64dbg, and behavioral sandboxes (Cuckoo, CAPE, etc.)
• Strong understanding of endpoint security technologies , especially EDR platforms and the internal workings of how detection signals are generated and triaged
• Deep knowledge of operating system internals (Windows, Linux), including memory management, process/thread architecture, registry, and system calls. Familiarity with Extended Berkeley Packet Filter (eBPF) and container security is highly valued
• Knowledge of cloud threat landscape , and threats and attacks targeting Linux, containers, and K8s
• Experience with cloud security research/ cloud threat hunting or IR/ cloud pentesting or redteaming; and with cloud threat detection and cloud-native telemetry (AWS, Azure, GCP)
• Proficient in threat intelligence frameworks and methodologies , including the Diamond Model, MITRE ATT&CK, Kill Chain, and mapping TTPs to coverage and detection gaps
• Strong data analysis and pattern recognition skills , able to sift through telemetry, logs, and artifacts to derive meaningful insights that drive detection hypotheses and logic
• Skilled in programming/scripting for automation, analysis, and detection logic generation (mostly Python)
• Experience building and maintaining threat hunting playbooks , leveraging endpoint telemetry, behavior analytics, and threat intelligence to operationalize continuous threat detection
• Comprehensive understanding of threat actor behaviors , intrusion sets, and motivations and their tooling/ecosystem

Responsibilities

• Lead threat intelligence initiatives to proactively research, analyze, and assess emerging cyber threats, including ransomware groups, financially motivated actors with a focus on developing detection strategies
• Perform in-depth technical threat analysis , including malware reverse engineering (static/dynamic), campaign tracking, and infrastructure profiling, to inform and drive detection logic in endpoint detection and response (EDR) platforms
• Develop high-fidelity detection logic (YARA, platform rules etc) based on actionable intelligence derived from malware capabilities, actor TTPs, and behavioral patterns observed in telemetry and forensic artifacts
• Design and implement threat hunting strategies to proactively discover malicious activity, unearth novel attack patterns, and surface IOCs and BOIs across diverse environments
• Continuously curate and maintain a threat intelligence knowledge base , including actor profiles, toolsets, infrastructure usage, TTPs, and affiliations, with a special focus on tracking ransomware and their evolving ecosystems
• Monitor adversary infrastructure (C2s, exploit servers), and develop automated methods to fingerprint and track infrastructure reuse across campaigns
• Collaborate with detection engineers to align threat research with detection coverage gaps
• Produce actionable intelligence reports and detection recommendations for internal stakeholders, including concise executive briefings and deep technical analysis for detection engineering and response teams
• Stay ahead of the curve on malware trends, evasive techniques, and novel TTPs, and map findings to threat models (e.g., MITRE ATT&CK, Diamond Model) to maintain contextual awareness and detection depth
• Mentor and guide detection engineers , promoting a culture of continuous learning, collaboration, and threat-informed defense

Preferred Qualifications

• Relevant certifications such as GIAC GREM, CREA, CMA, OSCE3, or RECA
• Familiarity with CTI enrichment platforms and tooling , such as MISP, ThreatConnect, or commercial TIPs
• Practical experience in building detection pipelines , integrating threat intelligence with SIEM/EDR platforms
• Contributions to open-source tools, YARA rulesets, or CTI repositories
• Authored some blogs

Benefits

• Grant of Restricted Stock Units with a 4-year vesting plan, annual performance-based bonuses, and an employee stock purchase plan
• Flexible Time Off, on top of the standard 5 weeks vacation, flexible paid sick days, fully paid Short Term Sick/Nursing Leave, 16-week parental leave, grandparent leave, and additional company holidays
• Pension Insurance Contribution, Premium life insurance, Private medical care (for you and +1), and a Global Employee Assistance Program
• Monthly meal and well-being allowance, high-end MacBook/Windows laptop, work-from-home support, and in-office refreshments
• LinkedIn Learning, internal mentoring, educational support, generous referral bonuses, and optional company events (sports, BBQs, charity)
