Security Engineer, Exposure and Vulnerability Management

📋 Job Overview

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.

🎯 The Role

How We Operate

• 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.

✅ Key Responsibilities

• 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. Identify it, assess it, and drive it to remediation or removal.
• 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 center equipment.
• Run intake for pen test findings and external reports, and report exposure honestly: what's reachable, what's exploited in the wild, what's accepted and by whom.

📌 Required Qualifications

• 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 run prioritization that survives contact with reality: KEV, EPSS, reachability, and the judgment to overrule all three.
• 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've driven remediation at scale through teams that don't report to you and kept SLAs credible without burning the relationships.
• You can take a technology class most programs never touch, firmware or GPU stacks

🎁 Benefits

Our compensation package includes base salary, equity for all full time roles, benefits, and, for applicable roles, commissions plans. This range reflects a good-faith estimate based on the applicable pay scale, the range previously established for this role, the compensation of individuals currently in equivalent positions, and/or the budgeted amount for the position. Actual compensation may vary based on experience, qualifications, and other factors. We welcome compensation discussions if this range doesn't meet your requirements. Outstanding candidates may be eligible for adjusted terms, plus meaningful equity that ensures you benefit directly from the company's long-term performance. Total compensation may also include equity in the form of restricted stock units.
