At Kandou, we are redefining the economics of AI infrastructure. Our mission is to democratise AI by significantly reducing the Total Cost of Ownership (TCO) of hardware systems — a critical barrier to scalable adoption.
Our proprietary MIMO-over-copper technology powers a high-performance, chiplet-based AI memory fabric that is both scalable and energy-efficient. Unlike traditional interconnects, our solution reduces power consumption significantly while preserving high bandwidth and ultra-low latency — unlocking unprecedented efficiency for AI training and inference at scale.
Kandou’s architecture is not just an incremental improvement — it’s a foundational shift in how AI hardware is built for the future.
We are actively seeking a Firmware Architect either based in Hyderabad OR Bangalore.
Responsibilities:
Define firmware architecture for 224G/lane AEC retimer (boot, config, calibration, link training, equalization, FEC, telemetry)
Implement link training for IEEE 802.3ck (100G/lane) and 802.3dj (200G/lane), including adaptation algorithms and fallbacks
Own FEC interaction (KP4, RS-544) and telemetry pipeline for Predictive Telemetry
Lead silicon bring-up, partnering with ASIC design and signal integrity
Ensure standards compliance (IEEE 802.3ck/dj, OIF-CEI, CMIS, OSFP)
Partition HW-fixed vs. FW-adaptation (equalization, SNR monitoring)
Travel: Up to 15% (silicon bring-up, standards meetings)
Skills:
Good knowledge of C (C99, MISRA), assembly for critical paths, Python for tools
Good knowledge of CI/CD, static analysis, hardware-in-loop tests
Good understanding of standards implementation (IEEE 802.3, OIF)
Good knowledge of SerDes architecture (equalization, telemetry, interrupts)
Self-motivated, with strong sense of ownership and responsibility
Good communication and reporting skills
Experience:
Principal / Senior Staff (8-10 years post-degree)
8-10 years embedded firmware in high-speed SerDes/retimer products
Hands-on PAM4 adaptation (LMS/CMA), FEC (KP4/RS-544)
Silicon bring-up as lead (first samples to production)
IEEE 802.3ck and 802.3dj link training experience
RTOS (FreeRTOS/Zephyr) on constrained MCUs (1MB flash, 256KB RAM)
Education:
BS in Electrical Engineering, Computer Engineering, or Computer Science (MS preferred, DSP/comms focus)
If this is the role you have been looking for and you want to be part of a growing Company, with an exciting future then we would really love to hear from you. Together We Kandou It!
