Hardware Engineer, Architect (AI)

Location: Silicon Valley, United States; hybrid

Company

hirify.global develops foundational hardware and software for the semiconductor industry, AI infrastructure, and advanced computing systems.

What you will do

• Define silicon and system microarchitecture for a custom unconventional compute platform targeting LLM and diffusion model inference.
• Design AI accelerator compute blocks, including processing-element arrays, datapaths, sparsity support, and reduced-precision computation.
• Translate transformer and diffusion workloads into hardware specifications covering compute tiles, memory hierarchies, and tile interconnects.
• Build performance models and make full-stack power, performance, and area trade-offs across algorithms, memory, interconnect, and physical design.
• Co-design the instruction set architecture and programming model with the compiler team.
• Direct block-level pre-silicon validation with FPGA design engineers and systems architects, and assess AI accelerator research directions.

Requirements

• Degree in electrical engineering, computer engineering, computer science, or equivalent experience.
• Substantial experience architecting or microarchitecting high-performance digital systems such as AI accelerators or complex compute engines.
• Experience translating workload analysis into datapaths, pipeline stages, and area and power estimates.
• Experience using cycle-accurate or analytical simulation models to guide architecture decisions before RTL implementation.
• Experience with quantization, reduced-precision inference, microarchitecture specifications, and collaboration with RTL engineers.
• Proficiency in Python or C++ and familiarity with SystemVerilog or equivalent RTL.

Culture & Benefits

• Collaborate across hardware, compiler, RTL, analog, FPGA, systems, and research teams.
• Work in an environment where the architecture is actively discovered alongside implementation.
• Participate in research-adjacent work, including reading and potentially publishing research.
• Inclusive equal-opportunity workplace with reasonable accessibility accommodations.
