DPU RAS and Debug Architect, Infrastructure Silicon

Meta's Infrastructure Silicon organization designs custom silicon that powers our data center infrastructure - SmartNICs/IPUs/DPUs, AI accelerators, and networking ASICs.

We are looking for a Data Processing Unit (DPU) RAS and Debug Architect to define the reliability, availability, and serviceability architecture for our DPU ASICs. You'll set FIT-rate targets from the intended usages and deployment models, define how errors are detected, corrected, and reported, and define the trace, debug, and performance-monitoring architecture that supports both post-silicon debug and software and firmware debugging. You'll decide what belongs in hardware versus firmware versus software, define how the hardware presents itself to firmware and software, and work hand in hand with the firmware, driver, and RTL teams - carrying your designs from early path-finding through implementation and silicon bring-up.Own the RAS and debug architecture for our DPUs - error detection, correction, and reporting, FIT budgeting, and the trace, debug, and telemetry infrastructure - from early path-finding through silicon bring-up Set FIT-rate targets from the intended usages and deployment models, and budget them across the design - memories, logic, on-chip interfaces, and links Define the error detection, correction, reporting, and containment architecture -- parity, ECC/SECDED, poisoning and poison propagation, error logging, and how errors are surfaced to firmware, host software, and platform management Define the trace, debug, and performance-monitoring architecture for post-silicon debug and for software and firmware debugging - on-chip trace, event and counter telemetry, crash and state capture, and the JTAG/debug-access model Decide what belongs in hardware versus firmware versus software, and define how the hardware presents itself to them - register and programming models, error and interrupt models, and trace/telemetry interfaces Work closely with design, DV, and PD teams on feature definition and PPA tradeoff; refine architecture to meet the design and PD constraints. Define architecture to maximize DV complexity including defining specific features to help ease DV Support Design, DV, PD and DFT teams to resolve interface and integration issues as they come up.

Familiarity with data center reliability, serviceability, and manageability requirements Experience with error-protection mechanisms - parity, ECC/SECDED, CRC, data poisoning and poison propagation, and lockstep/redundancy techniques - and their area, latency, and power trade-offs Experience with memory and interface RAS -- LPDDR/DDR RAS (ECC, on-die ECC, error scrubbing, post-package repair) and PCIe RAS (Advanced Error Reporting, ECRC, link error detection and recovery) Experience with error reporting and handling architectures (ARM and/or x86) - error logging and registers, interrupts, machine-check and AER-style reporting, and escalation to firmware, host software, and platform/BMC management Experience with on-chip debug and trace architectures -- JTAG and debug access, on-chip trace, breakpoints and watchpoints, and crash and state capture (e.g., ARM CoreSight or comparable) Experience with performance-monitoring architectures - hardware performance counters and event telemetry - and their use in post-silicon and software/firmware debug Experience with DFT concepts (scan, MBIST/LBIST, boundary scan) and how they interact with RAS and debug Experience with processor ISA debug mechanisms (ARM and/or x86) and instruction/execution trace mechanisms such as ETM Experience with relevant industry standards and specifications, such as OCP (server, RAS, and telemetry/manageability specifications), JEDEC (LPDDR/DDR), and PCIe Experience driving analysis independently and influencing architectural direction through data PhD in Computer Science, Computer Engineering or Electrical Engineering 15+ years of relevant industry experience architecting RAS and debug/trace architectures and their hardware/software interfaces for NIC/DPU or comparable ASICs Experience with hardware description languages (e.g., SystemVerilog, VHDL) and simulation environments used in ASIC development flows Experience designing on-chip trace and debug subsystems (e.g., ARM CoreSight) and the associated post-silicon debug tooling Experience defining FIT budgets and reliability targets for hyperscale data center silicon, including soft-error rate (SER) analysis and mitigation Familiarity with functional-safety standards (e.g., ISO 26262) and reliability qualification methods Experience developing Python-based (or other scripting) automation pipelines for debug, telemetry collection, and data analysis Experience designing error-reporting and machine-check/AER architectures and the firmware error-handling flows built on themMeta builds technologies that help people connect, find communities, and grow businesses. When Facebook launched in 2004, it changed the way people connect. Apps like Messenger, Instagram and WhatsApp further empowered billions around the world. Now, Meta is moving beyond 2D screens toward immersive experiences like augmented and virtual reality to help build the next evolution in social technology. People who choose to build their careers by building with us at Meta help shape a future that will take us beyond what digital connection makes possible today-beyond the constraints of screens, the limits of distance, and even the rules of physics.Meta is proud to be an Equal Employment Opportunity employer.
