Security Engineer: Protect AI Compute Fleet

Fluidstack; New York (NY); On-site; USD 150,000 - 210,000; Full time

Job summary

Fluidstack is seeking an experienced security engineer to own end-to-end security for our bare-metal fleet and high-scale infrastructure in New York. You will design, implement, and operate hardened systems, and partner with hardware and software teams to secure the frontier of AI compute.

We value deep Linux hardening, encryption, and zero-trust networking, with fluency in Python/Go/Rust and automation tools.

Qualifications

• You've worked in information security or infrastructure engineering with a strong focus on bare metal, IaaS, or high-scale cloud infrastructure.
• You harden Linux deeply (SELinux, AppArmor, kernel-level security) and command network security (TCP/IP, VPNs, firewall rulesets, zero-trust).
• You implement encryption in practice, including disk-level (LUKS) and hardware-level, and you understand HSMs and trusted computing (TPM/TXT).
• You automate fluently in Python, Go, or Rust, with configuration management (Ansible, Puppet, Chef).
• You work well across engineering teams and communicate security decisions clearly.
• Bonus: BMC platforms (OpenBMC, iDRAC, iLO). Hardware root of trust and secure boot. Compliance standards (SOC 2, ISO 27001, FedRAMP). CISSP, OSCP, or CEH.

Responsibilities

• Own end-to-end security for every server in the bare metal fleet, from supply chain and provisioning through hardening, operation, and secure decommissioning.
• Design and maintain hardened golden OS images with automated vulnerability scanning, patch pipelines, and configuration-drift detection.
• Define and enforce the BMC security model (access control, credential rotation, audit logging, firmware integrity) for one of the most under-defended surfaces in the industry.
• Partner with network engineering on micro-segmentation, IDS/IPS, and firewall architecture, applying zero-trust from the top-of-rack up.
• Implement data-at-rest encryption, key management, and secure storage access at fleet scale, and build the automation that makes secure-by-default the path of least resistance.
• Lead threat modeling and security reviews for new hardware platforms and network designs, and respond to incidents touching the physical fleet.
