Security Architect, Frontier AI Infrastructure

Fluidstack; San Francisco, New York, Austin, Seattle (CA, NY, TX, WA); Ibrido; USD 200.000 - 260.000; Tempo pieno

Descrizione del lavoro

Fluidstack is hiring for a security-focused role to protect frontier AI compute infrastructure. You will own the attack surface, design end-to-end security architectures, and ensure defensible environments from bare metal to multi-tenant software layers.

Responsibilities include security design reviews, threat modeling, and building scalable security controls across accelerators, interconnects, storage, and schedulers.

Competenze

• You’ve secured AI, ML, or HPC infrastructure where the assets were genuinely worth stealing.
• You can architect isolation at every layer it exists: hardware, firmware, hypervisor, kernel, container, network fabric, and physical.
• You understand AI compute infrastructure as a system (accelerators, high-speed interconnects, parallel storage, schedulers) and know where each component breaks a classical security assumption.
• You've done original work in systems or ML security, published or shipped, and can turn research into architecture that engineers actually build.
• You defend design decisions in review on their merits, and change them when someone closer to the metal proves you wrong.
• Bonus: Confidential computing and attestation depth. Weights custody or cryptographic key custody at scale. A publication record in systems or ML security.

Mansioni

• Own the attack surface unique to frontier compute: model weights custody, training environment isolation, accelerator and interconnect security, and multi-tenant boundaries under real adversarial pressure.
• Design the reference architectures and standards that security engineering builds to, keeping the seam between design and build clean enough that both sides move fast.
• Treat the workload as part of the threat model, and architect environments that stay defensible even when the thing running inside them is the adversary.
• Run security design review for the systems that touch training and inference environments, from bare metal and fabric to scheduler and storage.
• Track where frontier compute is going (new accelerators, interconnect generations, confidential computing, agentic workloads) and have the architecture ready before it lands.
