• Conduct ad-hoc threat hunts in support of SecOps, detection, automations or tools
• Collaborate across teams (site, product, engineering, IT) to understand and protect all aspects of Klaviyo's cyber footprint

We’d love to hear from you if you have :

• Hands-on experience with data science / machine learning techniques to identify threats
• Hands-on experience with SIEM and centralized logging (e.g., Splunk, Snowflake)
