About this role.
Fastly is seeking a Japanese- and English-speaking Threat Detection Analyst to support its Customer Security Operations Center and customers facing Internet-scale application threats. The role monitors and analyzes customer activity, investigates account-takeover and bot attacks, administers WAF-related security controls, and supports agent software deployed in customer environments. It requires practical SOC and application-security experience across cloud environments, web servers, scripting, and Linux or Windows administration. The analyst will work an overnight UTC shift aligned to Australian business hours, Friday through Tuesday, while collaborating with security, operations, and customer-facing teams. Strong bilingual communication, customer troubleshooting, and the ability to operate with limited supervision are central to success.

Sample interview questions
I would first validate the alert and define the affected accounts, endpoints, IP addresses, and time window. I would review authentication logs, request patterns, device or session indicators, geolocation anomalies, and WAF or bot signals to distinguish credential stuffing from legitimate traffic. I would then recommend or implement containment measures such as rate limits, bot rules, IP or ASN controls, stronger authentication controls, and enhanced monitoring, while documenting the findings clearly for the customer.
I would examine the matched rule ID, request URI, headers, parameters, payload characteristics, response outcome, and the business function of the affected endpoint. I would verify whether the traffic is legitimate, identify the narrowest safe exception, and test the proposed change in a controlled manner. The goal is to reduce false positives without broadly weakening protections or masking genuine attack patterns.
I would confirm the agent version, installation method, service status, logs, configuration, permissions, network connectivity, DNS resolution, proxy settings, and outbound firewall requirements. I would compare the environment to supported prerequisites and reproduce the issue where possible. I would communicate a concise diagnostic summary, remediation steps, and any needed escalation artifacts such as logs, timestamps, and relevant configuration details.
I use scripting to automate repetitive analysis, normalize logs, enrich indicators with contextual data, validate configurations, and generate consistent customer reports. For example, a Python or shell script can aggregate suspicious request patterns by IP, endpoint, user agent, and rule match to speed triage. I ensure automation is documented, reviewed, and designed to avoid exposing sensitive customer data.
I would lead with the business impact, what was observed, the actions already taken, and the recommended next steps, avoiding unnecessary jargon. I would tailor the detail for each audience while ensuring the Japanese and English updates communicate the same facts, severity, and ownership. I would also provide a written summary with timelines, evidence-based conclusions, and clear follow-up actions.
