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.
An evident self-starter with intellectual curiosity and the ability to adapt to change.

Responsibilities

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.
