Firmware Developer

Role & responsibilities

• Boot & Security: Implement our secure boot chain (BootROM PBL/SBL RTOS), device identity, attestation, anti-rollback, and field updates that protect our customers' valuable AI models and data.
• Hardware Bring-Up: Initialize clocks, power, HBM, PCIe, NoC, and SerDes PHYs often before our silicon arrives (emulation/FPGA), ensuring first-time-right deployment.
• High-Speed Networking: Bring up 400G Ethernet interfaces, configure MAC/PCS/FEC layers, and coordinate with network stack for RDMA offload engines essential for distributed AI training.
• Runtime Excellence: Power/thermal control, DVFS, watchdogs, RAS (ECC, crash dumps), and error recovery that delivers the 99.99% uptime our datacenter customers demand.
• Host Communication: Design mailbox protocols, MSI/MSI-X, DMA coordination, and health reporting with our Linux driver team to enable seamless integration.
• Telemetry & Observability: Unified event tracing with synchronized timestamps (PTP/PHC) giving our customers unprecedented visibility into their AI infrastructure.
• Multi-Die Scaling: Discovery, link training, topology management, and load-balancing hooks across chiplets because AI models keep growing.
• Validation & Documentation: Own bring-up guides, scripted tests, HIL/emulation validation, and HAL/config schemas that enable our global support team and customers.

Preferred candidate profile

• 5+ years embedded firmware (C/C++/Rust) on ASIC/SoC or GPU-like accelerators
• Proven experience with one of the complex high-speed subsystems is a must: PCIe bring-up (enumeration, BARs, MSI-X, DMA engines), memory subsystems (HBM/GDDR/DDR), high-speed Ethernet 100G+
• Configuration and management of clock/power domains, and RAS features
• Comfortable reading schematics, register specs, and debugging with JTAG/logic analyzers
• Strong documentation and code review habits your code will be the foundation others build upon
• Systems thinking: understanding how firmware decisions impact the full stack from silicon to application
