What You’ll Do

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

• Counter threat actors at a scale most practitioners never encounter — and build the capabilities to stay left of boom
• Work alongside security partners who hold a high bar and expect you to raise it
• Shape how CoreWeave finds and responds to the threats that matter most, with the autonomy to build and execute at the highest level

About the role:

• Leading the most complex, highest severity cybersecurity incidents at CoreWeave end-to-end – with full ownership of outcomes, not just coordination
• Reading smoke — authoritatively forming hypotheses about what's burning and a strategy to attack it before you can see the fire directly
• Serving as a clear, credible voice to senior leadership during active incidents — translating fast-moving technical situations into risk and decision frameworks that drive action
• 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
