ASIC Engineer, Architecture

Job Title

ASIC Engineer, Architecture

Role Summary

Work in Meta's Silicon Engineering organization to define and drive architectural performance analysis, pre-silicon modeling, and microarchitectural exploration for custom infrastructure ASICs. Partner with architecture, RTL, physical design, and software teams to align microarchitectural trade-offs with throughput, latency, and efficiency targets for data center and AI workloads.

Experience Level

Mid-level; requires approximately 6+ years of experience in ASIC design, silicon engineering, or a related technical field, with significant experience in performance modeling and microarchitectural analysis.

Responsibilities

Primary responsibilities center on performance-driven architecture exploration, modeling, and collaboration across hardware and software teams.

• Drive microarchitectural exploration and trade-off analysis across compute, memory subsystem, interconnect, and I/O domains.
• Define and own performance modeling strategy, including cycle-accurate and transaction-level simulation environments.
• Develop and maintain C++ models of chip IPs and subsystems for architecture exploration, performance analysis, and software development.
• Develop low-level workloads and kernels for machine learning training and inference to exercise and evaluate silicon designs.
• Establish benchmarking frameworks, bottleneck identification techniques, and performance-analysis methodologies across the ASIC pipeline.
• Collaborate with architecture, RTL design, and physical design teams to translate performance requirements into implementable microarchitectural specifications.
• Partner with software and systems teams to co-optimize scheduling, firmware, and drivers against silicon performance characteristics.
• Lead technical reviews, communicate modeling results and architectural recommendations to engineering leadership, and mentor engineers on modeling and analysis best practices.
• Identify and resolve performance gaps between modeled and measured silicon behavior through root-cause analysis and model calibration.

Requirements

Must-have technical skills and experience; preferred skills are listed separately.

Must-have

• Approximately 6+ years of experience in ASIC design, silicon engineering, or related technical fields.
• 5+ years of experience in ASIC performance modeling, microarchitectural analysis, or pre-silicon simulation for custom silicon or SoC designs.
• Proficiency in C++ and Python for simulation models, automation, and performance tooling.
• Experience developing cycle-accurate or transaction-level performance models (C++/SystemC) for processors, memory subsystems, or high-speed interconnects.
• Experience with performance analysis of data center, AI accelerator, or high-performance computing workloads on custom silicon.
• Experience defining microarchitectural specifications and driving cross-functional alignment across architecture, RTL, and physical design teams.
• Familiarity with assembly programming languages and compiler technologies.

Nice-to-have

• Experience with AI numerics, data types, math functions, and precision/accuracy analysis.
• Familiarity with post-silicon performance validation and model-to-hardware correlation methodologies.
• Experience with high-level synthesis, PPA trade-off analysis, or PPA-driven microarchitectural optimization.
• Experience building or scaling performance modeling infrastructure for hyperscale data center ASICs (network, storage, AI inference).
• Experience with HDLs (SystemVerilog, VHDL) and ASIC simulation environments.
• Experience writing and optimizing compute kernels in CUDA or equivalent GPU frameworks.
• Experience developing Python automation for simulation orchestration, regression testing, and performance data analysis.

Education Requirements

Bachelor's degree in Computer Science, Computer Engineering, or a relevant technical field, or equivalent practical experience.
