Senior🎓
Top SchoolDennis Jarosch is a seasoned engineering leader with 26 years of experience building large-scale payment and platform products, currently serving as Senior Vice President of Engineering at Ripple. Previously he led Square’s Payment Platform as GM, directing a 200+ person organization that powered over $150B in annual payments and spanning product, design, and engineering. He pairs deep hands-on systems and low-level engineering experience—from early C++ and embedded work to extracting and replatforming core services—with PhD-level research training, enabling him to translate product vision into robust, production-grade platforms. Born in Germany and raised across multiple countries, he brings a global perspective and a practical maker’s mindset—seen in contributions to hardware monitoring drivers and a DIY Sprinter-van project—that informs pragmatic, user-centered infrastructure decisions.
