Citi's Security Operations Center (SOC) Incident Response Team seeks a highly skilled and experienced incident response practitioner to support critical efforts aimed at protecting Citi infrastructure, assets, clients and stakeholders. This is a demanding role with global exposure and responsibility. You will serve both as a technical subject matter expert and as an ambassador for the incident response team. You will be assigned to Citi's SOC and will collaborate closely with a talented cadre of security specialists and incident responders to react urgently to security events. Your observations and recommendations will impact security decisions across the organization, and play an important part in maturing Citi's security posture.
As an individual contributor, you will be a hands-on first responder who triages and investigates cybersecurity incidents in cloud, traditional (i.e. on-premises), and hybrid environments. This position will be technically challenging and rewarding, but will also provide ample opportunity to establish partnerships, mentor colleagues and shape team culture. One guarantee is that no two days will be the same.

- Create and track metrics based on the MITRE ATT&CK Framework and other standard security-focused models.
- Work with application and infrastructure stakeholders to identify key components and information sources such as environments (on-premises versus cloud), servers, workstations, middleware, applications, databases, logs, etc.
- Participate in incident response efforts using forensic and other custom tools to identify any sources of compromise and/or malicious activities taking place.
- Collaborate with global multidisciplinary groups for triaging and defining the scope of large scale incidents.
- Document and present investigative findings for high profile events and other incidents of interest.
- Participate in readiness exercises such as purple team, table tops, etc.
