Summary
👤
Senior🎓
Top SchoolStamatis Markianos-wright is a Staff Applications Engineer at Arm with eight years of hands-on experience in compiler engineering, specializing in GCC and ARM architectures. He has progressed through roles from graduate scheme to staff-level, contributing to projects like Morello (CHERI capabilities) and early Rust on ARM64, and routinely drives upstream fixes, testsuite improvements, and customer-facing support. His open-source work includes notable GCC contributions around M-Profile Vector Extension intrinsics and resolving vectorization internal compiler errors, evidencing deep expertise in SIMD/vector codegen. Comfortable across the toolchain, he blends low-level codegen changes with systems bring-up (including Linux kernel support) and practical test-case engineering. Beyond engineering, he has managed an intern and led cross-team rotations that span compiler front- and back-ends, benchmarking, and product support. He pairs rigorous technical depth with a history of applied problem-solving in both industry and volunteer settings.
