Physical Security Engineer, R&D

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.

Role Scope

• Engineer physical security systems in the reference design: access control, video, intrusion, and perimeter detail by detail.

• Produce the design packages: drawings, device schedules, and specs the integrators build from.

• Integrate the systems: security platforms tied into site networks, monitoring, and identity.

• Support deployment: site surveys, punch walks, and acceptance testing on your own designs.

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 designed or engineered physical security systems for commercial or critical facilities.

• You produce buildable packages: riser diagrams, device layouts, and schedules.

• You've configured and tested access control and VMS platforms hands-on.

• You coordinate with electrical and IT design instead of clashing with it.

• You've supported installs and closed the punch yourself.

• Bonus: Lenel, Genetec, or equivalent platforms. Data center security standards. Network fundamentals. CAD or Revit fluency.

We are committed to pay equity and transparency.
