Our Product Management team drives product initiatives from inception through execution, makes impacts and launches products/features across our global footprint. We collaborate closely with engineers, designers, analysts, marketers, and other cross-functional team members to ship remarkable features and products. Role Overview We are looking for a Senior Product Manager, Trading to own trading products on the Crypto.com App end-to-end. Retail trading is where users feel the product every day - and where volume, engagement, and retention compound. Every improvement you ship shows up in how people trade, how often they come back, and how Crypto.com wins share in a crowded market. Your mandate is to drive trading products from discovery through launch and iteration: roadmap clarity, feature definition, customer insight, and shipping at global scale. You will run your roadmap with independence within Trading's strategic priorities. You prioritize initiatives, cut tradeoffs, and make the call on what ships when. You report to the Senior Director of Product Management, who sets strategic direction. You own the how and the when. If you've shipped trading or financial products at scale, this will feel familiar. The difference is you'll be doing it at the frontier of crypto retail trading- perpetuals, spot, and adjacent markets- where the rails keep moving and the playbook is yours to write. No layers. No politics. What You'll Actually Do: Own the Trading roadmap. You set milestones, surface dependencies, and keep strategic priorities honest. You make the prioritization call when everything can't ship at once. Define and ship trading experiences. You write the specs, run user studies, iterate on feedback, partner with QA on test plans, and clear the backlog. Nothing in your charter goes live without your sign-off. Stay close to how traders actually behave. You interview and observe customers. You ask "Show me how you currently
