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. ## Description * 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, , 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. ## Related Videos - [Our journey with Spring Boot in a microservice architecture](https://www.wearedevelopers.com/videos/511-our-journey-with-spring-boot-in-a-microservice-architecture) - [Understanding Kubernetes in a visual way](https://www.wearedevelopers.com/videos/100085-understanding-kubernetes-in-a-visual-way) - [Beyond Chat: AI Workflows That Actually Investigate Alerts (So You Don't Have To Know Everything)](https://www.wearedevelopers.com/videos/100308-beyond-chat-ai-workflows-that-actually-investigate-alerts-so-you-don-t-have-to-know-everything) - [You can’t hack what you can’t see](https://www.wearedevelopers.com/videos/41-you-can-t-hack-what-you-can-t-see) - [Instant KAI Sandboxes with vCluster: Multi-Tenant, Multi-Scheduler GPU Sharing](https://www.wearedevelopers.com/videos/100333-instant-kai-sandboxes-with-vcluster-multi-tenant-multi-scheduler-gpu-sharing) - [Microservices: how to get started with Spring Boot and Kubernetes](https://www.wearedevelopers.com/videos/242-microservices-how-to-get-started-with-spring-boot-and-kubernetes) ## Related Articles - [9 Ways to Make Money Hacking](https://www.wearedevelopers.com/magazine/333-9-ways-to-make-money-hacking) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer)
