The posting

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.

As Firmware Lead, you will lead implementation and delivery of real-time embedded firmware for Kandou's Randa 1.6T Active Electrical Cable platform. This is a coding-heavy technical leadership role: you will spend the majority of your time writing and reviewing C/C++, debugging firmware and hardware interactions, and supporting pre-silicon and post-silicon bring-up. You will turn the Firmware Architect's system design into production code, own implementation quality and delivery, and mentor engineers while remaining active in the codebase.

Open locations: India (Hyderabad or Bangalore), UK (Reading or Cambridge), Switzerland (Lausanne).

Responsibilities

• Lead the implementation and delivery of real-time embedded firmware for AEC retimer silicon across 224G/lane, 448G/lane and forward-looking 896G/lane configurations; remain a hands-on C/C++ contributor.

• Implement and maintain boot, configuration, calibration, link-training, fault-recovery and run-time supervision state machines on resource-constrained RISC-V or ARM platforms.

• Translate approved firmware architecture into module designs, APIs, task and interrupt models, memory budgets and hardware/software contracts; surface implementation tradeoffs early.

• Code, debug and optimize firmware for SerDes equalization and adaptation, FEC-aware monitoring and re-adaptation, telemetry capture, thermal behavior and power management.

• Own low-level drivers and management interfaces including SPI, I2C/SMBus, I3C, MCTP and JTAG, and integrate firmware services with the CMIS management layer.

• Drive pre-silicon development and first-silicon bring-up; isolate issues across firmware, RTL, boards and lab setups using JTAG, register traces and targeted instrumentation.

• Set coding and review standards; build unit, integration and hardware-in-loop tests; enforce CI, static analysis and release evidence; improve Python-based build, debug and test tools.

• Break the roadmap into deliverable work packages, estimate and track execution, mentor firmware engineers and coordinate with architecture, ASIC, DV, validation, SI and applications teams.

Essential Experience

• 8+ years developing and debugging production real-time firmware in C/C++, including 2+ years leading firmware modules, projects or a small team.

• Expert hands-on C/C++ in resource-constrained systems, with recent evidence of personal code delivery, code review and complex defect resolution.

• Firmware experience on a retimer, gearbox, PHY, AEC, AOC, optical module, networking ASIC or comparable high-speed mixed hardware/software product.

• RISC-V and/or ARM bare-metal or RTOS firmware, including interrupts, traps, CSR or register access, concurrency and tight RAM/flash budgets.

• RTOS development with Zephyr, FreeRTOS or equivalent; ownership of scheduling, synchronization, timing and failure recovery.

• At least one silicon or board bring-up cycle using JTAG and related debug mechanisms, with root-cause analysis across firmware, drivers, RTL and hardware.

• Python, Git/GitLab, Make/CMake, CI, unit and integration testing, and static analysis, with disciplined reproducible development workflows.

BS in Electrical Engineering, Computer Engineering or Computer Science, or equivalent experience; strong communication, planning, mentoring and cross-functional leadership.

Useful experience

• IEEE 802.3ck or 802.3dj link training and equalization, SerDes adaptation algorithms, channel-quality monitoring and register-level PHY tuning.

• FEC exposure including KP4 or RS-544, pre-FEC and post-FEC telemetry, symbol-error analysis and FEC-aware recovery behavior.

• CMIS 5.x firmware integration, module or datapath state machines, VDM telemetry, and sideband protocols including SMBus, I3C and MCTP.

• Bootloaders, secure boot, root of trust, authenticated A/B firmware updates, rollback protection and field-recovery mechanisms.

• Pre-silicon firmware development using QEMU, SystemC, FPGA, simulation or emulation; heterogeneous multicore or vector-processing systems.

PCIe or CXL, hyperscaler qualification, interoperability debugging, and production support for field or manufacturing issues.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
