Firmware Architect

Apply for this Role →
What you'll do Firmware & Embedded Software Architecture Leadership  Own the end-to-end firmware/embedded-software architecture for TYL chiplets.   On-die: boot and secure boot, link sequencing, PCIe/CXL controller configuration and enumeration, address-translation (NTB/ATT) setup, MSI-X and AER handling, reset/FLR, power management, telemetry, and in-field firmware update.   Host-side: kernel drivers, the device-virtualization/transparency shim (synthetic PCIe device, VFIO-mdev-class), management libraries/APIs, and IOMMU (VT-d/SMMU) coordination.   Define the hardware/software boundary with architecture and RTL — datapath (credit, ordering, merge/split, address-translation execution) in RTL; control plane in firmware — and own register maps and UCIe sideband/mailbox protocols.   Stay hands-on through first silicon.  Bring-up, Methodology & Quality  Drive pre-silicon firmware and host-software development on emulation, and virtual platforms, and lead post-silicon bring-up and debug.   Stand up the firmware engineering infrastructure: CI, automated and HIL testing, requirements traceability, secure-development practices (secure boot, attestation, key management), and the RAS/error-handling and fault-attribution strategy.   Define firmware release, quality, and security criteria across products and customers.  Cross-functional & Customer Collaboration  Be the technical bridge between firmware/software and architecture, RTL, PHY/IP vendors and program management — bringing software feasibility into hardware decisions early.   Work directly with customers: compute-SoC partners on PCIe/CXL enablement, ATE/SLT integrators on the firmware and management libraries.  Team Building & Management  Set technical direction, roadmap, and clear subsystem ownership (boot/security, PCIe/CXL management, host drivers and virtualization, RAS/telemetry).   What We're Looking For BS/MS in Electrical / Computer Engineering or Computer Science  12+ years of embedded firmware development, with at least 5 years in silicon-level bring-up and validation of high-speed interface IPs.  Expert-level C and assembly for resource-constrained embedded CPUs (RISC-V or Arm Cortex-M/R class); strong debugging skills using JTAG/OpenOCD, trace, and logic analysers.  Deep PCIe expertise: link-training state machine, equalization (Gen3 EQ/LFSR, Gen4/5 preset search, Gen6/7 Flit Mode), speed-change sequences, LTSSM register-level behaviour.  Hands-on experience with HPC compute SoC firmware ecosystems — UEFI/BIOS bring-up, ACPI table authoring, SMBus/I2C/MCTP platform management, VT-d/IOMMU configuration — on HPC platforms.  Solid understanding of x86 server platform boot flow: SEC → PEI → DXE → BDS, PCIe enumeration in PEI/DXE, Option ROM interaction, and PCIe error-recovery paths (AER, DPC).  Experience with secure-boot architectures, code-signing flows, and OTA update mechanisms on embedded targets.  Comfortable working at the hardware-software boundary: reading RTL schematics, memory-mapped register specs, and waveforms from simulation or a logic analyser.  Good To Have CXL 2.0/3.0 firmware experience: HDM decoder programming, CXL IDE, DVSEC, BISnp coordination.  UCIe / die-to-die sideband firmware experience (RDI/FDI parameter negotiation, sideband messaging).  SPDM (DSP0274) and CMA device-attestation implementation experience.  Familiarity with PLDM for firmware update (DSP0267) and platform telemetry (DSP0248).  ATE scripting background — Teradyne UltraFLEX / Advantest T2000 board-level bring-up scripts.  Exposure to chiplet packaging concepts (UCIe, EMIB, CoWoS) and multi-die power-sequencing considerations.  Kernel-mode driver or UEFI DXE driver development experience.
