We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.
We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.
We hire people who care deeply about this problem space. If that is you, please apply!
Be a barrel. Full autonomy. Own things end to end, take on scope without being asked, no permission required to operate outside your core role.
Insane urgency. We drive everything forward as fast as possible.
Reason from first principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.
Build something that actually matters. If you're going to spend your time, spend it on something that matters to the world.
Examples of key problems the team is working on
You're securing the frontier of AI. The model weights training on our infrastructure are the most valuable and most targeted artifacts in technology, and we're standing up the compute to hold them faster than anyone ever has. A breach isn't a leak, it's the frontier walking out the door.
Build the entire security program from scratch. Most leaders inherit someone else's system and spend a career patching it. Here you own it end to end, bare metal to boardroom, as we scale across continents.
Your threat surface is measured in gigawatts. The customers running on our infrastructure are building the most consequential technology in human history, and being responsible for the physical and logical security of that work makes everything else feel small.
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.
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
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.
We are committed to pay equity and transparency.
