As a Senior DFIR Analyst, you will be tasked with serving as technical lead on small to medium-sized breach response investigations for SentinelOne's 24x7x365, follow-the-sun DFIR team. You'll own case-level evidence and documentation quality end-to-end, partnering closely with an Engagement Manager on scoping, case strategy, and customer communications, and bringing strong, well-rounded technical depth across threat hunting and endpoint, network, and cloud forensics.

What Will You Do?

Primary responsibilities include:

• Serve as technical lead on DFIR engagements, directing analytical focus and partnering with the Engagement Manager to align technical work with scope and client expectations.

• Support case intake by gathering initial technical details and assessing scope.

• Conduct EDR-driven incident response and vendor-agnostic advanced forensic analysis spanning endpoint, network, cloud, and SaaS environments (including ransomware, business email compromise, identity compromise, and other common incident types).

• Develop tactical containment guidance and remediation recommendations tailored to each engagement's specific attack pattern.

• Contribute observed attacker techniques and indicators to the team's shared knowledge base.

• Acquire and preserve forensic evidence from endpoint, network, and cloud sources following standard chain-of-custody procedures, with clear, thorough case documentation throughout each investigation.

• Support the preparation and delivery of interim status updates and deliverables.

• Own evidence handling, documentation standards, and the accuracy and quality of formal investigative reports for assigned engagements, ensuring findings are defensible, well-supported, and peer-reviewed before reaching a customer, breach counsel, or other stakeholder.

• Lead case handovers for assigned engagements, ensuring a complete, clear transfer of status when work moves across regions.

• Mentor Analysts on technical methodology, evidence handling, and investigative best practices.

• Manage triage and analysis in high-pressure, large-scale incidents, maintaining composure and clear decision-making.

• Build or improve scripts, tooling, and internal processes — including AI-assisted approaches where useful — to streamline recurring forensic, analysis, and reporting workflows.

• Escalate scope, resourcing, or customer relationship concerns to the EM promptly, while owning technical escalations directly.

• Track hours for investigations accurately and in a timely fashion.

• Participate in a rotating on-call schedule for weekends and holidays, to support active incident response.

• Maintain awareness of emerging threats, attacker techniques, and evolving cybersecurity trends.

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

• Bachelor's or Master's degree in Digital Forensics, Cybersecurity, Computer Science, or a related technical field (or equivalent practical self-study).

• 4+ years of hands-on experience in digital forensics, incident response, or threat hunting, ideally in a consulting or services delivery environment.

• Demonstrated experience serving as a lead or technical contributor on complex breach response engagements, capable of working independently with minimal guidance.

• Comfort analyzing Windows, Linux, and macOS environments.

• Expert-level experience with forensic investigative tools such as X-Ways Forensics, Axiom, and FTK.

• Strong experience with EDR/XDR platforms (SentinelOne preferred) and SIEMs.

• Strong understanding of network protocols, network security architecture, and network-based forensic analysis.

• Working knowledge of cloud incident response methodology across at least one major provider (AWS, Azure, or GCP).

• Experience conducting dynamic malware analysis and solid understanding of the reverse engineering process.

• Experience conducting endpoint-based threat hunting (compromise assessments).

• Scripting ability (Python preferred), with experience automating investigative or analysis tasks.

• Demonstrated ability to write clear, evidence-backed findings and reason through ambiguous or incomplete data in writing.

• Comfort communicating findings to a range of stakeholders, including customer technical teams, executives, and legal counsel.
