🚀 About Flow Flow is massively accelerating the development of next-generation hardware systems. We’re on a mission to reinvent the way humanity develops its most important machines.
We’re backed by Sequoia Capital with angel investors including Patrick & John Collison (Stripe), David Helgason (Unity) and Kyle Parrish (Figma).
Flow is the default requirements tool for complex systems engineering used by next gen space, defense, automotive and robotics companies. When humanity returns to the Moon, builds fusion power, or lands the first interplanetary colony - Flow will have played a vital role.
🌉 About the Role
Flow’s customers are the world’s most ambitious hardware companies designing rockets, humanoid robots, nuclear reactors, and more.
As one of our first Sales Engineers, you’ll sit at the intersection of sales, engineering and customers: understanding how next-gen hardware teams build, showing how Flow can transform their development process and guiding them from first conversation through to successful adoption.
You’ll partner directly with our Founder & CEO to shape how Flow sells, builds relationships and brings new customers onboard without traditional account executives in the mix. Every sales engineer at Flow owns their accounts end-to-end.
This is an ideal role for someone who started their career as a hardware engineer, then discovered they love working with customers to solve their problems. At Flow this means implementing effective solutions that help other engineers design much faster.
