Senior Incident Response Analyst

Responsibilities About the Team The TikTok USDS JV Security Operations Center (SOC) is responsible for global around-the-clock monitoring, response, mitigation, and resolution of critical security events to protect and defend TikTok US data, infrastructure, customers, users, and products. Aside from monitoring TikTok US infrastructure and networks for indicators of anomalies, breach, and/or unauthorized access, the SOC is responsible for leading response efforts to enterprise-wide incidents, including post-incident root-cause analysis and recovery efforts, as well as leading proactive investigations into threats otherwise unidentified, developing and maintaining response plans, playbooks, and procedures. About the Role This role is based in our Converged Security Operations Center in Washington, D.C., working closely in a follow-the-sun model with our global SOC counterparts in London and Sydney.

Responsibilities You will drive technical response actions to protect our stakeholders and US-based users from increasingly fast-paced and AI-driven threats and attackers, including develop and tuning alerts to quickly identify anomalous and/or malicious activity occurring within TikTok USDS JV infrastructure. You will leverage AI-driven and agentic tools and methodologies, paired closely with your investigative and problem-solving skills to conduct comprehensive investigations and root-cause analysis to guide the business in unearthing, evicting, and recovering from attacks from sophisticated threat actors. You will collaborate closely with a variety of partner teams, including the Hunt team, Cyber Threat Intelligence, Digital Forensics, Legal, and Infrastructure teams to coordinate seamless, effective, and efficient operations. To be most successful in this role, you must excel in highly complex, ambiguous situations, transforming chaotic incident signals into clear paths forward to ensure the resiliency of our critical US operational infrastructure, customers, users, and data.
