Rockstar🎓
Top SchoolAaron Hartwig is an engineer with 11 years of hands-on experience co-designing hardware and software for high-performance, real-time systems. Currently at Oxide Computer Company, he focuses on embedded and infrastructure-level engineering, contributing to projects like the memory-protected Hubris kernel with FPGA work for QSFP transceivers and I2C/LED control. His background spans FPGA design for ultra-low-latency trading at IMC, medical-device electrical and firmware systems at GE Healthcare, and full-stack and embedded development from internships. Aaron holds a BSE and an MS in Electrical and Computer Engineering from UW–Milwaukee and is a Tau Beta Pi member, reflecting his technical rigor. He combines protocol-level firmware, FPGA RTL, and CI-driven verification practices, and often bridges electrical, firmware, and testing disciplines to simplify complex architectures. Based in Wisconsin, he prefers to focus on deep technical work locally rather than exploring new roles or relocation.

Contributions summary:Aaron primarily contributed to the embedded systems aspects of the `hubris` kernel, focusing on the sidecar front-io module. Their work involved updating and integrating FPGA binary files, specifically related to QSFP (Quad Small Form-factor Pluggable) transceivers. They added features like I2C communication, transceiver port mapping, and LED control for system monitoring. Furthermore, the user implemented the power enable and control sequence for QSFP modules through the FPGA.
