Senior Digital Forensic Investigator

Posted Monday, December 22, 2025 at 5:00 AM About eSentire eSentire is on a mission to hunt, investigate and stop cyber threats before they become business disrupting events. We were founded on the premise that if you can’t find a solution, you build it. Entrepreneurship and innovation are in our DNA. Our culture is based on transparency, teamwork, and continuous innovation. As the authority in Managed Detection and Response, we protect the critical data and applications of 2000+ organizations in 80+ countries, across 35 industries from known and unknown cyber threats. The Role The Senior Digital Forensic Investigator serves as a tactical arm of eSentire’s Incident Response team. Main function of this role is to drive deep expertise and experience in incident response, and digital forensics engagements. As a top tier operator, the position handles the most volatile and complex casework, while ensuring optimum quality of service and responsiveness. Casework spans from financially motivated data breaches to state‑affiliated espionage and ideology‑driven attacks aimed at information gathering, manipulation and disruption. Real domain expertise, mixed with ability to execute, and mastery of relevant technologies must produce investigative conclusions that withstand scrutiny in the court of law. The position operates in close coordination with eSentire’s SOC and Customer Success Management teams to drive fast mobilization, source identification, containment, and quantification of informational losses in response to cyber attacks in motion.
