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.

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.
