Content Designer

Perplexity is looking for a Content Designer to shape the words across our products. You'll design the language people see and hear across our family of Perplexity apps, from the first screen of onboarding to the way an agent explains what it's doing. Fundamentally, we are all writers. Our product is primarily spoken language and written product; but as we scale, we want someone who will continue to work on clarity, usefulness, and keep it unmistakably Perplexity. You're a designer first? You're an engineer first? You're a writer first? Your shape is not conventional, and you wear many hats. You are fluent in AI tooling. You have strong UX fundamentals and good product instincts. You use language to solve product problems: flows, naming, information architecture, error states, permissions, and moments where people need to trust what the product is telling them. You command words. You command agents, and make decisions about words. You can write one perfect line, and you can build the system that keeps thousands of lines consistent. You'll sit on the Design Systems team and work closely with product designers, engineers, PMs, research, brand, and marketing. (Again) You're fluent in AI-powered tools and use it every day. You understand how models behave, how prompts and system instructions shape what people see, and how to define and judge quality when the output isn't fully deterministic.

What you'll do

Design and write in-product language across web, mobile, desktop, and voice, including UI copy, flows, onboarding, notifications, empty states, errors, and in-product education Partner with product designers from the start of a project, shaping flows, structure, and information architecture as well as the words in them Name features and products, and own terminology, navigation labels, and taxonomies so the product stays easy to understand as it grows Make complex AI and agent behavior understandable, including what the product is doing, why, what it can't do, and when it needs a person's input Shape how AI-generated content reads by writing and refining prompts and system instructions, and help define voice and response style for our models in product Define content quality standards and help build evaluation criteria, datasets, and reviewer guidance for AI-generated content Build and maintain voice and tone guidelines, content patterns, and content guidance in our design system so every team can write well Use research, data, and experiments to test language and improve comprehension, activation, and task completion Partner with brand and marketing so product language and our external voice feel like one company Work with internationalization partners so the product reads well in every language we support Review copy in code and ship small language changes directly when it's the fastest path
