Job description

About Fluidstack

We exist to make humanity more free. 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 acquire power, design and build data centres, and operate them - with teams spanning hardware and software. Come be a part of building civilization-scale infrastructure for AI.

We hire people who care deeply about this problem space. Love of the game. The frontier of AI is the most interesting problem of our time. 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. 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 exposure and vulnerability management across the estate: external attack surface, cloud and Kubernetes, corporate endpoints, network infrastructure, and the bare-metal fleet beneath them.

Extend exposure and vulnerability management across the corporate fleet (macOS, Windows, Linux): OS and application patch posture, first‑party and third‑party software, and drift from approved baselines.

Cover software outside our managed and approved catalogs: unmanaged apps and SaaS, package‑level software on endpoints (npm, PyPI, Homebrew), and browser and IDE extensions. Build the engineering that makes it work: asset inventory, scanner orchestration, deduplication, and prioritization built on reachability and real‑world exploitation rather than raw CVSS.

Engineer remediation into the workflows teams already use, so findings land as owned tickets, fixes ride existing pipelines, and closure verifies automatically.

Remediate alongside the teams that own the systems: write the patch PR, harden the base image, fix the IaC module, and ship the config change rather than just requesting it.

Extend the program past where enterprise playbooks run out: BMC and device firmware, GPU drivers, host images at fleet scale, and the long tail of data centre equipment.

You've built vulnerability management as an engineering problem: pipelines, automation, and integrations rather than spreadsheet triage.

You write production‑quality automation (Python or similar) and have wired scanners, asset systems, and ticketing into something coherent.

You've fixed vulnerabilities yourself, in someone else's codebase or infrastructure, and your pull requests got merged because they were good, not because security demanded it.

You can take a technology class most programmes never touch, firmware or GPU stacks or data centre equipment, and stand up a defensible assessment approach instead of waiting for a vendor to sell you one.

You've run vulnerability and exposure coverage on corporate endpoints and third‑party software, including the unmanaged long tail of shadow apps, packages, and extensions.

Bonus: External attack surface management platforms. Endpoint management and patching tooling (MDM, EDR), software inventory, and extension and supply chain risk.

We are committed to pay equity and transparency.
