Summary
👤
Senior🎓
Top SchoolUsama Arif is a software engineer with eight years’ experience building low-level firmware and platform software for leading silicon and consumer companies, currently at Meta after stints at TikTok and Arm. He specializes in embedded systems, ARM Trusted Firmware and SCP firmware, contributing device-tree support, platform bring-up, PSCI multicore enablement, and interconnect configuration for Total Compute—work visible across high-profile open-source repos. Comfortable operating at the intersection of hardware and software, he has a track record of adding DVFS, SCMI services and low-level register support that bridge AP–SCP communication. His career spans product-focused roles at TikTok and silicon-focused engineering at Arm, giving him both systems-scale and production-delivery sensibilities. Based in Cambridge, he pairs an Imperial College MEng background with practical experience in cross-team integration and upstream open-source contribution. An under-the-radar strength is his repeated success getting platform-level patches merged into major upstream projects, reflecting both technical depth and collaborative discipline.

Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:30 commits, 1 PR, 1 comment in 2 years 10 months
Contributions summary:Usama primarily contributed to the ARM Trusted Firmware-A repository by modifying platform-specific definitions and code related to ARM architecture, focusing on the Versatile Express and DesignStart platforms. Their work involved renaming variables, introducing support for new platforms (FVP Versatile Express and A5 DesignStart), adding device tree configurations, and enabling multi-core support through the use of PSCI. They also implemented a software division function and updated the MHUv2 interrupt number.
