About Fluidstack

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!

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.

About the Role

Fluidstack, a leading cloud provider, is looking for a Platform Engineer to build the foundational platforms that enable our global infrastructure and data center operations. You'll develop comprehensive internal tooling across multiple domains—CMDB, asset management, DCIM, monitoring and observability, security, and operational automation—that streamline how we deploy, manage, and operate infrastructure at scale. Working cross-functionally with engineering, operations, data center teams, and product, you'll deliver scalable, reliable, user-friendly solutions that directly impact our ability to grow and deliver world-class infrastructure services.

Focus

Infrastructure Platform Development

Design and build our next-generation CMDB system as the authoritative source of truth for infrastructure assets, network topology, and configuration data

Create DCIM platforms for rack operations, server/GPU deployment, OS installation, quality assurance, and white-screen operations

Develop end-to-end asset lifecycle management systems covering receiving, racking, inventory, break-fix, and decommissioning workflows

Build monitoring and observability platforms integrating telemetry from BMS, EPMS, and IT devices with intelligent alarming and incident management

Create self-service portals and automation for new region bootstrap, day-2 operations, and fleet-scale management

Operational Excellence & Automation

Eliminate manual toil through workflow automation and self-service tooling that empower operations and engineering teams

Build workflow orchestration systems for complex multi-step processes spanning incident, problem, and change management

Develop digital twin visualizations and operational dashboards surfacing actionable insights; partner with data teams on analytics

Create integration layers connecting internal platforms with external vendors and third-party systems

Cross-Functional Partnership

Collaborate with data center operations, system engineering, network engineering, and security teams to understand requirements and deliver high-impact solutions

Work with product and business stakeholders to prioritize features, define roadmaps, and balance competing needs

Align with support and operations teams to ensure platforms scale with organizational growth

Technical Leadership

Evaluate build vs. buy decisions for platform components, weighing in-house development against commercial SaaS and open-source solutions for scalability, cost, and flexibility

Champion modern development practices including CI/CD, infrastructure-as-code, automated testing, and observability-first design

Participate in architecture reviews and design discussions, contributing to technical direction and standards

Foster technical excellence through code reviews, documentation, and knowledge sharing

Scalability & Reliability

Design high-performance, fault-tolerant systems capable of handling thousands of QPS as our infrastructure footprint expands

Build comprehensive monitoring, logging, and debugging capabilities with robust error handling

Implement data migration strategies and manage upstream/downstream dependencies carefully during platform evolution

Own projects end-to-end from concept through deployment, ensuring production readiness and operational excellence
