The posting
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. And today, that means pioneering the future of AI-powered security. At eSentire, we're building a cutting-edge AI Security Operations Platform that will amplify human expertise, not replace it, creating a workplace where innovation meets impact. Our culture is based on transparency, teamwork, and continuous innovation, where your ideas can shape how AI and human intelligence work together to outsmart cyber adversaries. As the authority in Managed Detection and Response, we protect the critical data and applications of 2000+ organizations in 80+ countries, across 35 industries—and we're looking for forward-thinking talent to help us define what AI-first security, human-backed trust means for the industry. About the Role: The Senior 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. Make no mistake, Incident Response work is an extremely demanding role. Cyber attacks don’t follow a schedule. Our team must be available when they happen. As a result, our team members are often called upon to work outside regularly scheduled work hours, through weekends and holidays, with little notice. On the flip side, when it’s not busy we do encourage our team members to make the most of that time and catch up on their personal business. Please give this some thought before you apply, this is a demanding and equally rewarding job, but it’s not for everyone. Responsibilities
