Software Engineer, Ontology

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 weve ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who dont share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.

Were 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 youre going to spend your time spend it on something that matters to the world.
