Network Engineer, Team Lead

Socket.dev; New York (NY); On-site; USD 180,000 - 280,000; Full time

Job summary

Fluidstack is seeking a Senior Network Engineering Lead to guide the network team and drive scale for AI frontier compute infrastructure. You will own hiring, strategic priorities, and cross-functional delivery across design and operations.

You will own the network roadmap from fabric generations to backbone expansion, ensuring alignment with the build plan and production needs. This role requires building a capable team ahead of demand to support rapid growth.

Qualifications

• Led network engineering organizations through rapid scale.
• Hired network engineers in a competitive hiring market.
• Balanced roadmap work with day-to-day operations.
• Led teams to ship faster through effective team governance.

Responsibilities

• Lead the network engineering team: hiring, growth, priorities, and delivery across design and operations.
• Own the network roadmap from fabric generations to backbone expansion, sequenced to the build plan.
• Run the operating rhythm between design, deployment, and production so the network org moves as one.
• Build the team ahead of demand: networks at this scale require engineers the market barely produces.

Job description

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. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.

• Velocity. We drive everything forward as fast as possible.

• 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.

The Network Team

Examples of key problems the team is working on

• Build the networks the frontier of AI trains on. Fabrics for 100k+ accelerator clusters, backbones between gigawatt campuses, and every network in between.

• Run 10s to 100s of GWs of networks as one machine. Training fabrics for 100k+ accelerators, backbone, corp, and BMS/EPMS, one architecture across gigawatt campuses.

• Deliver a full site network in days, not quarters. Designs generated from source-of-truth models, devices turned up by ZTP, every link validated by machine. At this scale, manual is an outage.

Role Scope

• Lead the network engineering team: hiring, growth, priorities, and delivery across design and operations.

• Own the network roadmap from fabric generations to backbone expansion, sequenced to the build plan.

• Run the operating rhythm between design, deployment, and production so the network org moves as one.

• Build the team ahead of demand: networks at this scale need engineers the market barely produces.

What We're Looking For

• 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 led network engineering organizations through rapid scale.

• You've hired network engineers in a market where everyone is hiring them.

• You balance roadmap work and operations without letting either starve.

• Engineers you've led ship faster because of how you run the team.

• Bonus: AI and HPC networking. Multi-site programs. Vendor relationship ownership. Automation-first organizations.

We are committed to pay equity and transparency.
