Senior Security Engineer I Advanced Response

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

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 we’ve found compatible with our team. We'd love to talk about whether this aligns with your experience and interests and what you’re excited to work on next.

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 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

Please note that this role is not a typical 9-5 job. There will be instances where your skills are needed outside of business hours. On-call hours (including weekends and holidays) and leadership during active incidents is expected. If building a world-class response and threat hunt program — and actually answering the call when you’re needed — is what gets you going we'd love to connect.
