What Youll Do

CoreWeave powers the worlds most demanding AI infrastructure and threat actors know it. The Advanced Response Team exists to fight back. Youll lead our most critical incidents hunt adversaries before they surface and build the capabilities that define how CoreWeave defends itself at scale.

• Conducting deep technical investigations and hunts across endpoint cloud identity and network data sources to establish scope timeline and root cause
• Producing rigorous risk-driven post-incident reviews that go beyond surface-level timelines and result in concrete durable improvements
• Running a structured threat hunting program informed by operationalized intelligence turning actor profiles campaign reporting and TTP gaps into hunts and turning hunt findings into durable actions to harden CoreWeave and improve our response posture
• Architecting and building AI-powered tooling that drives how CoreWeave counters threats accelerating work left and right of boom
• Developing and running incident simulations and tabletop exercises that stress-test real-world response capabilities before a real incident does

Investing in our people is one of our top priorities and we value candidates who can bring their diversified experiences to our teams. Here are some qualities weve found compatible with our team.

• Experience briefing senior leadership and non-technical stakeholders during active incidents with clarity and composure
• Comfort leading and operating across organizational boundaries pulling the right people in at the right time without losing ownership of the outcome
• Proficiency in at least one query language (e.g. SQL Splunk Query Language HiveQL)
