Threat Hunt Senior Operator

The Threat Hunt Senior Operator (THSO) works to identify advanced threats within the network to track and mitigate them prior to an attack of the IT systems of the organization. The THSO will create hypotheses to conduct searches for threats inside the network with the goal of gathering data on threat behaviors, goals, and methodologies of the threat group. The THSO is responsible for organizing and analyzing the data to establish baselines for the security environment and make security recommendations to address current vulnerabilities and will mentor junior personnel on the use of tools and proper analysis of data. The THSO will coordinate the work efforts of the Threat Hunt team and conduct quality assurance (QA) of junior analyst work.

Candidate will possess prior work experience in cybersecurity with an intimate knowledge of network computing and be an individual who has technical skills with multiple security tools. The individual will be responsible for gathering raw data, filtering, investigating, analyzing network activity, creating the hypothesis for threat hunt operations, conduct full hunt operations, and solution security fixes based on the outcome of the hunt. The THSO will operate as part of the Incident Response team by assisting with the response through the conduction of ad-hoc hunts, contributing to lessons learned and suggesting new preventative measures, and integrate threat data into security tools. The individual will have good presentation skills and possess excellent communication skills both verbal and written.
