Careers
A team of builders, researchers, and operators.
We have led foundational AI research, scaled products used by governments and the world's largest enterprises, and operated companies through periods of rapid growth. We are building H to advance AI systems that can be trusted in the real world.
The H mindset
Six values that guide how we build and decide as a team.
Progress over perfection
Ship fast, learn faster.
Impact first
Work on what creates real value.
Ambition
Think big, build bold.
Be a H owner
We take pride in building the company together.
Curiosity
Explore, ask, stay sharp.
Integrity
Speak honestly, act kindly.
How we work
A fast-moving, collaborative team
We run hackathons, go on offsites to recharge, and celebrate wins as a team. You'll work alongside world-class engineers and researchers in a high-trust, multicultural environment.
You're part of the mission
Everyone at H is free to take the initiative, fix what's broken, and own the result. People work closely across teams, disciplines, and borders, and ideas get better as they move between them.
