Senior Product Designer

In 1964, the Italian design company Danese asked Bruno Munari to create a lamp that was practical, durable, economical, and compact enough to carry easily. Munari thought of the rice paper lanterns he had encountered in Japan, but rice paper was fragile, difficult to clean, and prone to yellowing.

Looking for an industrial alternative, he discovered filanca, a synthetic stretch nylon used exclusively for women’s stockings. It was inexpensive, flexible, durable, heat-resistant, and washable.

Munari went to a hosiery factory and asked them to make him a lamp.

“We do not make lamps, sir. Only stockings.”

Munari told them to wait and see.

The result was the Falkland lamp: only a few centimeters thick when packaged and as tall as a person when hung. Its shape emerged from the elasticity of the nylon, a series of metal rings, and gravity.

Munari didn’t begin with the form of a lamp. He began with the qualities it needed, then looked outside the conventions of lighting to find the right materials and methods. We’re looking for a product designer who works the same way: someone who studies the systems and materials at hand, then finds a way of putting them together that feels both unexpected and inevitable.

At Co–Star, the materials are a 4,000-year-old system of astrology, planetary data from NASA, and a corpus written by astrologers and poets. The design problem is how to make all of that legible, intuitive, and fun on a phone.

We’re hiring a Senior Product Designer to work on Co–Star’s core mobile product and new experiments. You’ll move between product architecture, interaction design, prototyping, and visual design. Ideas here rarely arrive as polished specs. You’ll help determine what we should make, how it should work, and what form it should take.

What you’ll do

• Own major product surfaces end-to-end: concept, flows, interaction, visual polish, ship
• Invent interaction paradigms for things that haven't existed before and make those new paradigms legible and fun 
• Use research, experimentation, analytics, and user feedback to understand what people need and where products can improve.
• Prototype constantly, in Figma and in code — we expect tools like Claude Code and Cursor to be part of your workflow 
• Partner directly with engineering to refine interactions, iterate quickly, and ship high-quality work.

What you'll bring

• You've spent the last decade designing software people love to use.
• You're comfortable moving between interaction design, visual design, and product thinking.
• You enjoy working closely with engineers.
• You agree that good work often emerges out of many rounds of iteration. You explore wildly, always ready to kill your darlings, and rework ideas until something clicks and feels correct.
• You'd rather prototype than make a presentation.
• Work > ego
