Senior Product Designer (Paris/NYC) Hyperline

We are looking for a senior Product Designer to own design at Hyperline end to end. You will shape how the product looks, feels, and works, from the first sketch to the shipped screen, and set the quality bar for everything that comes after.

You will work directly with the founders and engineering, ship fast, and get your work in front of real customers quickly. You own the whole problem, not a stack of handed-down specs. You frame the problem, not only style the solution, and you decide what good looks like here.

It is a real craft challenge too. The category is full of ugly, confusing tools, and the product handles genuinely complex things. A designer who can make that feel simple and obvious has enormous room to stand out.

What You’ll Own

• The end-to-end design of Hyperline’s core product surfaces

• Turning complex billing, usage, and finance concepts into clear, usable flows

• Interaction and visual quality across the product, held to a high bar

• A design system that keeps the product coherent as it grows

• Prototyping and iterating quickly, including with AI tools

• Designing the AI and agent experiences of the platform, a near blank canvas in this category

• Working directly with engineering on what is buildable, scalable, and worth building

• Bringing product judgment to which problems to solve, not only how they look
