About the position
Session Replay is one of Mixpanel’s fastest-growing product areas, giving our customers powerful visibility into user behavior by letting them watch how people actually interact with their products. Our team builds full stack experiences that help customers debug, optimize, and deeply understand user journeys, from capturing rage clicks and console errors to building heatmaps and cross-page replay stitching. As a Full Stack Engineer on the Session Replay team, you’ll work across the stack to deliver high-impact, user-facing products. You’ll collaborate closely with teammates in engineering, product, design, and go-to-market to iterate quickly and push the boundaries of what’s possible in behavioral analytics. Our ideal candidate is someone excited to balance frontend polish with backend robustness, and who isn’t afraid of diving into ambiguity, exploring technical trade-offs, or owning a project end to end. You’ll get to work in a fast-paced, product-led environment where your work directly impacts thousands of customers — and millions of users.
