Senior Firmware Engineer at Infineon Technologies
Embedded systems and firmware engineer specialising in automotive Ethernet, Linux device drivers, and real-time OS development. 3+ years delivering production-grade solutions across Infineon and Marvell.
// 01 — About
I'm Arun Suthar, a Senior Firmware Engineer at Infineon Technologies in Bengaluru, working at the intersection of automotive networking, real-time operating systems, and low-level driver development.
My work focuses on firmware development for Infineon's automotive Ethernet switch solutions — building Ethernet drivers, integrating PTP and lwIP stacks on FreeRTOS, and developing internal protocols such as ARP and I2C. I also handle switch configuration, SDK build setup, and test automation pipelines.
Before Infineon, I spent over two years at Marvell Technology contributing to the Driver Development Team, designing and developing drivers for Marvell Automotive Ethernet Switches on Linux and QNX (io-sock and io-pkt). I also have hands-on experience with IoT hardware, PCB design (2-layer boards), and ESP32-based embedded systems from my earlier engineering roles.
I hold an M.Tech in Embedded Systems from MNIT Jaipur and a B.E. in Electronics & Communication from GEC Gandhinagar.
