Top SchoolYujia Qiao is a software engineer with nine years of hands-on experience in systems, networking, and distributed infrastructure, currently on the CoreDev team at Jump Trading. A 2023 graduate from Huazhong University of Science and Technology, he has interned at Alibaba and Bytedance working on next-gen distributed filesystems and container runtime performance. He is an active open-source contributor with meaningful backend work in projects like Chapel, Kata Containers, and a Rust reverse proxy (rathole), often improving core data structures, consensus code, and test coverage. Known for competitive programming success (ICPC medals) and a self-driven learning approach, he brings both algorithmic rigor and pragmatic engineering to complex problems. Unusually for someone in trading tech, his public contributions include game development in C/SDL and audio handling, showing curiosity beyond pure infrastructure. He has accepted a return offer at Jump Trading and is not open to other opportunities.
