Senior Security Engineer (Advanced Response)

Join CoreWeave, a leading AI infrastructure provider, as a Senior Security Engineer on the Advanced Response Team. In this role, you will lead critical cybersecurity incidents, conduct deep technical investigations, and shape how CoreWeave responds to threats. You will have the autonomy to build and execute at the highest level, and work alongside security partners who hold a high bar. This position requires extensive experience in incident response, security operations, and threat hunting, as well as strong technical investigation and hunting skills.

• Lead and manage the response to complex cybersecurity incidents, taking full ownership of outcomes and coordinating with various teams.
• Conduct deep technical investigations and threat hunting across multiple data sources to establish scope, timeline, and root cause.
• Architect and build AI-powered tooling to enhance CoreWeave's threat detection and response capabilities.
• Proficiency in at least one query language (e.g., SQL, Splunk Query Language, HiveQL)
• Deep familiarity with attacker TTPs and how they manifest across cloud, endpoint, identity, and network environments
• Comfort leading and operating across organizational boundaries — pulling the right people in at the right time without losing ownership of the outcome
• Experience briefing senior leadership and non-technical stakeholders during active incidents with clarity and composure
• 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
• Ability to script or automate in Python, Go, or similar to close operational gaps and accelerate response and hunting workflows
• Experience building or materially maturing an IR program at a cloud-native organization
• Familiarity with SOAR platforms and case management tooling in an operational IR context
• Familiarity with Kubernetes or containerized environments, with appetite to go deeper
• Experience building and leveraging AI-assisted tooling in investigation or triage workflows
