About Fluidstack

Technology is the most important tool humans have found for improving the human condition, but it is not a default good. It is a lever for ideology.

Today the most powerful technology in history is being built: machines that solve problems better than humans can. The most important mission of our generation is to imbue AI with democratic values: error-correcting institutions, freedom of speech, individual liberties. AI trains and runs on massive compute clusters. Whichever ideology builds the infrastructure the fastest is the ideology that will endure. Democracy is delicate and won't survive this technology by default.

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.

The People Team

Examples of key problems the team is working on

Build the people function from scratch, fast enough to keep up with 10x growth. We grew headcount 10x in the last year and we're not slowing down. You'll build the systems, programs, and team from nothing, and make them work before we outgrow them.
Reinvent people operations around AI. Doing this by hand doesn't scale to a workforce growing this fast on a team this lean. You'll put AI at the core of how the function runs, so a small team supports many times its number.
Own the culture and comms as the company scales. When a company scales this quickly, staying connected and aligned doesn't happen on its own. You'll own the internal comms, events, and rhythm that keep a multi-site team that's growing fast bound to a shared culture.

Role Scope

Serve as the people partner for your client orgs: the first call for managers on hiring, performance, structure, and the hard conversations.
Own employee relations end to end: investigate, resolve, and document with judgment and speed.
Run the people rhythms for your groups: onboarding, reviews, engagement, and offboarding that scale with 10x growth.
Coach managers, many of them first-time, into leaders their teams would choose again.
Put AI to work on the function itself: automate the repeatable so partner time goes to judgment, not paperwork.

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 been an HRBP or people partner through rapid scaling, and your client leaders would hire you again.
You've run sensitive ER cases end to end and your investigations held up.
You've coached first-time managers into good ones.
You move at operating speed: same-day answers, not next-cycle policies.
You know employment law well enough to know when you need counsel.
You work the data: retention, performance, and engagement signals read early and acted on.
Bonus: Technical, field, or industrial client groups. High-growth startups. HRIS implementation. AI-native people ops tooling.

We are committed to pay equity and transparency.
