At ClickUp, we're building the future of work: the first truly converged AI workspace unifying tasks, docs, chat, calendar, and enterprise search, all supercharged by context-driven AI. We are an AI-native company. Every team member is expected to leverage AI daily, and we evaluate AI fluency as part of our hiring process. Join us and help redefine what's possible. 🚀 ABOUT THE ROLE We are hiring the next generation of product managers. AI has collapsed the work that used to sit between an idea and a working version of it, and for the first time, PMs can be true builders. The PMs who win in this era do not manage the work. They build the product, every day, with their own hands. A Senior Product Manager owns a meaningful surface of ClickUp and is accountable for whether it gets better. You decide what to build and why, then go build a working version of it. You prototype in Cursor and Claude when an idea is faster shown than written. You live in the data and the customer signal, and the time between spotting a problem and having something people can react to is measured in days, not weeks. The PMs who compound the most impact at this level are the ones who keep finding leverage that did not exist last quarter. KEY RESPONSIBILITIES Own the vision, roadmap, and delivery for a defined product surface, balancing near-term wins with longer-horizon investments. Run continuous discovery. Building and using agents to monitor and synthesize that part of your job. Write sharp PRDs and specs that give engineering and design what they need to move fast without ambiguity. Define success metrics before you build, track them after you ship, and iterate when outcomes do not match expectations. Prototype your own ideas using Cursor, Claude Code, and our Prototype Playground. Show the concept before filing the ticket. Collaborate cross-functionally with engineering, design, analytics, and GTM without needing to be managed through the process. Present your roadmap and results clearly
