Our AI-native platform unifies protection across endpoint, cloud, identity, data, and AI systems to deliver autonomous detection and response with clarity and speed. By combining real-time analytics, intelligent automation, and a unified data foundation, we reduce noise, simplify complexity, and empower security teams to focus on what truly matters.

Our teams are builders, problem-solvers, and innovators committed to shaping the future of security. If you are excited to solve hard problems alongside talented, mission-driven people, we invite you to help us build a safer future for humanity.

What Are We Looking For?

We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.

As a DFIR Analyst, you will be tasked with delivering rapid, expert breach response for global enterprises facing active cyber threats as part of SentinelOne's Digital Forensics and Incident Response (DFIR) team, which operates 24x7x365 on a follow-the-sun model. Working under the direction of an investigation's Technical Lead and Engagement Manager, you will execute hands-on forensic analysis, threat hunting, and investigative work across live incidents spanning endpoint, network, and cloud environments, and incident types from ransomware and business email compromise to identity compromise, zero-day exploitation, APT activity, and cloud/SaaS breaches. This is a foundational technical role built on rigor, where every conclusion must be evidence-backed, every case well-documented, and every finding able to hold up to scrutiny.

What Will You Do?

Primary responsibilities include:

• Conduct EDR-driven incident response and vendor-agnostic forensic analysis spanning endpoint, network, cloud, and SaaS environments, including ransomware, business email compromise, identity compromise, and other common incident types.
• Support malware and memory analysis tasks under the guidance of senior team members.
• Acquire and preserve forensic evidence from endpoint, network, and cloud sources, following standard chain-of-custody procedures.
• Support case intake by gathering initial technical details to assess scope, and support incident containment actions and security hardening recommendations.
• Maintain thorough case documentation throughout each investigation.
• Follow standard operating procedures and elevate technical or logistical questions to the assigned Technical Lead or Engagement Manager as needed.
• Contribute to customer-facing status updates, formal investigative reports, and handovers of investigations across regions as needed, distilling complex technical findings for stakeholders.
• Maintain awareness of emerging threats, attacker techniques, and evolving cybersecurity trends, and contribute observed techniques and indicators to the team's shared knowledge base.
• Be responsive to high-pressure triage and analysis during large-scale cybersecurity incidents, maintaining composure.
• Participate in a rotating on-call schedule for weekends and holidays.

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

• A bachelor's or master's degree in Digital Forensics, Cybersecurity, Computer Science, or a related technical field, or equivalent practical self-study, plus 2 or more years of hands‑on experience in digital forensics, incident response, or threat hunting, ideally in a consulting or services delivery environment.
• Comfort analyzing Windows environments and forensic artifacts, with a foundational understanding of forensic methodologies, evidence handling, acquisition techniques, and chain-of-custody procedures.
• Experience with forensic tools such as X-Ways Forensics, Axiom, and FTK; with EDR/XDR platforms (SentinelOne preferred) and SIEMs; and working knowledge of network protocols and network-based forensic analysis.
• Scripting and automation capabilities.
• Strong verbal and written communication, with comfort documenting and presenting technical findings clearly and precisely.
• Ability to perform technical investigations under pressure in high‑stakes, time‑sensitive situations, while maintaining composure.
• An evident self‑starter with intellectual curiosity and the ability to adapt to change.
• Knowledge of Linux and macOS forensic analysis, exposure to cloud environments (AWS, Azure, GCP) and memory analysis, and foundational experience conducting malware analysis and understanding the reverse engineering process are preferred.
• Familiarity with endpoint threat hunting, cyber threat intelligence platforms, the MITRE ATT&CK framework, and AI‑assisted tools for streamlining triage, analysis, or reporting workflows is preferred.
• Relevant industry certifications, such as GCFE, GCFA, GREM, CFCE, or EnCE, and interest in contributing to industry publications, research, or speaking engagements are preferred.
