Senior Security Engineer I, Advanced Response

About the role

The Advanced Response Team exists to fight back against threat actors. 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. Shape how CoreWeave finds and responds to the threats that matter most, with the autonomy to build and execute at the highest level.

Responsibilities

• 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
• 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

Requirements

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

Comfortable 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

• 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
