Staff Product Security Engineer

About Crusoe

Crusoe is on a mission to accelerate the abundance of energy and intelligence. As the only vertically integrated AI infrastructure company, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads. We're solving the AI compute bottleneck with an energy-first approach that makes AI infrastructure better for the world.

About This Role

We're seeking a Staff Product Security Engineer with deep AI/ML security expertise to strengthen Crusoe's security posture across applications, infrastructure, and distributed AI systems. This highly technical role focuses on advanced penetration testing, AI/ML attack surface research, and building secure-by-design guardrails that engineering teams rely on.

You'll operate at the intersection of offensive security, AI systems, and production engineering, owning security outcomes end-to-end while influencing system design across the organization.

What You'll Be Working On

• Performing advanced manual penetration testing across complex applications, infrastructure, Kubernetes environments, and distributed microservice ecosystems
• Leading offensive security initiatives including red team operations, adversary simulation, and security research
• Securing AI/ML systems end-to-end, including LLM pipelines, vector databases, RAG architectures, and agentic workflows
• Identifying and researching novel attack surfaces unique to LLMs and autonomous systems, contributing to internal and external AI security research
• Influencing secure system design across the SDLC, embedding security into CI/CD pipelines, container images, and deployment workflows
• Integrating and operationalizing security tooling (SAST, DAST, SCA, container scanning) and driving remediation of complex application-layer vulnerabilities
• Building internal security guardrails such as hardened base images, reusable libraries, and policy-as-code frameworks

What We're Looking For

Problem-solving, opportunity-finding teammates with a sense of urgency who believe in the scale of our ambition and thrive on a path not fully paved — people who want to grow their careers alongside experts across energy, manufacturing, data center construction, and cloud services.
