Context Engineering for Frontier Hardware

We help humanity accelerate the development of its most important machines. Hardware development today is 10% invention and 90% execution.


Physical Engineering AI is not an LLM problem — it's a context engineering problem. LLM's are strong at component design, but terrible at systems integration.


Flow has become the system of record for collaborative hardware development. Billions of data points on Requirements, Design, Test and iterations are flowing though our context layer. We are starting by accelerating Systems Engineering.


One day, we will go from Prompt -> Humanoid Robot. Prompt -> Self-Driving car. prompt -> Re-usable rocket.

Careers at Flow

Come build with us!

We build Flow the way we build our team

Flow is design to enable engineering teams move faster and collaborate better. We bring those same values to how we work together—moving quickly, fewer silos, and a focus on keeping things simple so teams can do their best work.

Operating principles

Speed over everything

If you go over a pothole at 20 mph, you really feel it. If you go over at 200 mph, you barely feel it. Everything we do, we need to do with urgency. This is our superpower and why we win. This is a discipline that requires effort and focus every day.

Own, downscope, ship, iterate

We work in small, fast cycles. Our philosophy is to downscope and ship. The goal is to get a v1 out today and learn from seeing it used. We work with users not at them. Execution is the sole currency by which our customers value us. This does not always mean success at the first iteration, but we must be fully committed to delivering.

Fundamentals done well

Most success comes from mastering the basics. The trade off is always scope, never quality. This is why we prioritize simplicity. Doing so requires extreme clarity of thought: a talent for cutting to the essence of a problem, communicating it well and then solving it.

Get on a plane

To move fast, we have to decide fast. That means debating ideas hard, then committing fully once a decision is made.

Maximum effort, maximum fun

Climbing Everest is a brutal test of spirit, yet we keep climbing. This is the work that defines us. Enjoy the journey, for the summit only matters if you loved the climb.

Enjoy the climb

Climbing Everest is hard. The air thins, your body falters, and you pass those who didn’t make it. But we’re here to keep climbing. This is the work that will define us. Enjoy the climb. The view at the top only means something if you loved the journey getting there.
