CoreWeave · Bellevue, WA · 1 mo ago

Hybrid$139k–$204k/yrFull-time

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

Who You Are

Extensive experience in incident response, security operations roles, and/or threat hunting at scale, with demonstrated ownership of complex, high-impact incidents from start to finish
Strong technical investigation and hunting skills — comfortable working hands-on with logs, telemetry, and raw system data to form and validate hypotheses, not just direct others to do it
Deep familiarity with attacker TTPs and how they manifest across cloud, endpoint, identity, and network environments
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)
Ability to script or automate in Python, Go, or similar to close operational gaps and accelerate response and hunting workflows

Preferred Experience

Experience building or materially maturing an IR program at a cloud-native organization
Familiarity with Kubernetes or containerized environments, with appetite to go deeper
Experience building and leveraging AI-assisted tooling in investigation or triage workflows
Familiarity with SOAR platforms and case management tooling in an operational IR context
