Cyber Security Operations Center (CSOC) Tier 3 Analyst

[Company Description]
Global Financial Company

We are looking for a talented manager level professional to work for the Cyber Security Operations Center (CSOC) which is part of the corporate function of Information Security Office (ISO).

The candidate will be functioning as the first line of defense for the company. This position is much more than just watching an incident queue. You will have the opportunity to develop integrations, correlations, and SIEM content to better protect the environment.

The CSOC, and the larger ISO, are dynamic teams that look for self-motivated talent, meaning the CSOC will embrace and leverage the background and skill sets you bring to the table to better protect the overall organization.

Ideal candidates will enjoy solving complex security incidents in a fast-paced Information Security environment. Candidates would utilize their background in networking, operating systems, and security tools/knowledge to not just remediate any incidents that arise; also work with the CSOC Directors and members to create custom detections, alerts, and reporting to further improve the capabilities of the CSOC.

Ideal candidates are comfortable working in a potentially high stakes environment, while working off potentially incomplete/not ideal information/conditions. Being a high-tier Analyst, this position is expected to help the CSOC Director in leading the team of Analysts, potentially functioning as a site/shift lead, performing peer review, and helping to roll out new processes to the team. This position is expected to be actively involved in the direction and improvement of the CSOC, given the candidate's technical depth, as well as their knowledge of day to day operations. Candidates will be working under an experienced management team that has collectively over 25 years of InfoSec experience and has lived the life of an Analyst. Besides the more traditional SOC work event investigation/management, the candidate will have opportunities to become involved in the configuration of the tools/products used by the CSOC to better the CSOC as a whole. By joining the CSOC the candidate will have the opportunity to not just join a rapidly evolving team but provide their input towards the direction of the organization. Additionally, we believes in keeping up/expanding the technical and soft skills of our CSOC team members as they progress.
