Network Engineer, Wireless at Fluidstack (New York, NY)Network Engineer, Wireless

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!

• 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.

Examples of key problems the team is working on

• Build the networks the builders run on. Enterprise, campus, and wireless networks across gigawatt data center sites, offices, and labs: the connectivity every other team depends on to build and operate the fleet.
• Deliver wireless in the hardest RF environment there is. Full coverage across white space packed with dense rows of liquid-cooled racks and steel, on campuses that are still active construction zones.
• Connect sites from bare dirt to full production. Satellite backhaul on day one, enterprise-grade campus networks at turnover, one repeatable design stamped across every new site.

• Own enterprise and wireless network design and deployment across data center campuses, offices, and labs as a single repeatable reference design, with configs generated and version-controlled rather than hand-drawn per site.
• Deliver full wireless coverage in white space where the colocation landlord's obligation ends at the admin areas: dense double-wide liquid-cooled racks cause severe RF interference, and the design may need an AP on every row.
• Run predictive and on-site RF surveys, then validate coverage after equipment install, because a hall full of racks changes the RF answer.
• Build the security posture for active construction campuses: WPA3-class wireless, clean segmentation between production, controls, contractor, and guest traffic, and disciplined credential and SSID hygiene while hundreds of trade workers rotate through.
• Stand up interim construction-phase connectivity, including Starlink-class satellite backhaul before terrestrial circuits land, and drive the cutover to permanent enterprise networks.
• Coordinate with data center design, deployment, IT, and security teams so enterprise and wireless requirements land in the site design instead of being retrofitted after turnover.

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 jobs.ashbyhq.com

• You've designed and deployed enterprise campus networks end to end, wired and wireless, from requirements gathering through turnover to operations.
• You know 802.11 at the fundamentals: RF propagation, channel planning, and roaming behavior, and you've run predictive and on-site RF surveys with professional survey tooling.
• You've built NAC, segmentation, and guest and contractor access that held up under real-world abuse.
• You've delivered networks in industrial, construction, or otherwise RF-hostile environments and adapted your designs when the environment fought back.
• You troubleshoot from packet capture and spectrum analysis, and you can point to the trace that settled the argument.
• Version-controlled configs and documented designs are habits for you, so the next site inherits your work without a handover meeting.
• Bonus: Satellite or fixed-wireless backhaul experience. Wi-Fi design certifications. Enterprise routing and switching automation. Experience running networks alongside OT and BMS environments.

We are committed to pay equity and transparency.
