Summary
👤
Senior🎓
Top SchoolJun He is a senior software engineering manager with ~9 years of formal experience and over a decade of deep expertise in multimedia processing, embedded Linux, and mobile platforms. Currently leading engineering at Arm, he blends hands-on C/C++ performance work with team and project leadership across ARM/MIPS/PPC/DSP architectures and iOS/Android targets. He is an active open-source contributor and performance engineer—his optimizations for Zstandard and changes to the Seastar framework demonstrate tangible throughput and build-environment improvements on aarch64. Having chaired and committed to Apache Bigtop, he also brings significant DevOps and cross-platform build/test experience that improves release reliability across distributions. Known for rapid learning and clear multinational communication, he pairs low-level optimization instincts with pragmatic product delivery track record from startups to global silicon vendors. An interesting detail: he frequently tackles infrastructure and build-tool challenges that unlock performance gains as much as feature work, making him a hands-on leader for both systems and people.
