Network Operator, Data Center Operations

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.

How We Operate

• Extreme ownership
• Velocity
• First principles
• Love of the game

Role Scope

• Serve as the on-site Tier 3 escalation point for network and structured-cabling incidents across the site's AI infrastructure.
• Troubleshoot, diagnose, and resolve physical-layer faults, validate repairs, and drive rapid resolution of issues hitting customer workloads.
• Act as the escalation path for Tier 1 and 2 technicians, and partner with Network Operations on deeper investigations.
• Own structured cabling and fiber infrastructure, and interpret device-level diagnostics well enough to confirm a physical repair restored connectivity.
• Escalate out-of-scope issues to Network Operations with clear documentation, and take ownership through resolution as the sole on-site network and ICT resource.

What We're Looking For

• You've been the on-site network or cable-plant specialist in a data center, owning physical-layer troubleshooting end to end.
• You know structured cabling and fiber deeply (testing, termination, fault isolation) and you read device diagnostics well enough to validate repairs.
• You have enough network fundamentals (TCP/IP, switching, optics) to bridge cabling and the network stack.
• You operate as the sole escalation resource on-site and take incidents through to resolution.
• You document rigorously, so Network Operations can pick up cleanly when an issue exceeds on-site scope.

Bonus

• High-density AI or hyperscale fabrics.
• Fiber certification (BICSI, Fluke).
• Optical transport.
• InfiniBand or high-speed Ethernet.

Salary & Benefits

• Competitive total compensation package (salary + equity).
• Retirement or pension plan, in line with local norms.
• Health, dental, and vision insurance.
• Generous PTO policy, in line with local norms.
