Summary
🤩
Rockstar🎓
Top SchoolNathan Hartman is a Senior System Software Engineer with six years of experience specializing in power, performance and low-level systems for ARM SoCs, currently building power management firmware and DVFS drivers at NVIDIA. He brings a strong embedded systems background—contributing to widely used open-source RTOS work in Apache NuttX and PX4, where he restored drivers and added hardware-specific support for TI and STM32 platforms. Nathan’s work spans kernel and firmware layers, including Arm Trusted Firmware, Linux kernel runtime features, and profiling infrastructure for multiprocessor SoCs, reflecting a pragmatic hardware-software co-design approach. He pairs a 3.9 BASc in Computer Engineering from Waterloo with hands-on experience validating RTL on FPGA/emulation and authoring co-validation test plans. Colleagues benefit from his knack for turning subtle hardware revisions into unambiguous software abstractions and restoring critical device drivers that enable real-world IoT and robotics platforms.
