Co–Star is seeking a Senior Product Designer to work on our core mobile product and new experiments. You’ll move between product architecture, interaction design, prototyping, and visual design. You’ll own major product surfaces end-to-end: concept, flows, interaction, visual polish, and 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 from 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. This is a hybrid role based in San Francisco, United States.
