Joe Long is a Distinguished Engineer with 25+ years at Microsoft building massively scalable, multi-tenant distributed systems, cloud services, and enterprise middleware. He has led organizations from small incubations to 300+ person teams, architecting high-throughput commerce services that have processed peaks over 850,000 TPS and billions in revenue. His work spans core identity and directory services (AD-DS, AD-FS, AD-RMS), developer frameworks, and the Microsoft Store/Xbox marketplace, demonstrating deep expertise in reliability, security, and platform strategy. Joe blends hands-on engineering with executive leadership—defining architecture, processes, and anti-fraud strategies while still getting into the code and prototypes earlier in his career. Based in Woodinville, WA, he pairs a physicist’s analytical training from Reed College with a builder’s mentality captured by his “build to last” principle. Off hours he’s a curious tinkerer who enjoys experimenting with new tech—and apparently an enthusiastic cribbage player.
