Location: San Jose, California, United States

Annual base salary: USD 200,000–320,000

Company

hirify.global develops semiconductor and silicon technologies, including AI/ML accelerator architectures.

What you will do

• Define multi-generation memory and data transport architectures for AI/ML accelerators.
• Develop memory strategies covering HBM, LPDDR, GDDR, DDR, on-die SRAM hierarchies, and scratchpads.
• Architect memory controllers, cache and scratchpad microarchitecture, scheduling, address mapping, and QoS across compute, DMA, and host traffic.
• Own on-die interconnect topology, flow control, deadlock avoidance, mixed-traffic QoS, DMA, gather/scatter, layout-transform, and multicast engines.
• Build analytical and simulation-based models to quantify performance, power, area, latency, throughput, utilization, and scalability trade-offs.
• Co-architect solutions with internal teams and external memory and IP vendors across multiple silicon generations.

Requirements

• 18+ years of ASIC/SoC architecture experience focused on memory systems and data movement for HPC or AI.
• MSEE, MSCE, or PhD in EE, CE, CS, or a related field, or equivalent demonstrated architectural impact.
• Deep knowledge of HBM, DDR, LPDDR, GDDR, memory controller architecture, cache coherency, memory consistency models, tiered memory, and pooled memory.
• Demonstrated ownership of data movement architecture spanning on-die interconnects, DMA/copy engines, buffer hierarchies, and dataflow to compute.
• Practical understanding of the latency, area, and power costs of NVLink, UALink, RDMA, ARM CHI, UCIe, and PCIe.
• Strong performance modeling and system-level simulation experience, with first-principles command of latency, throughput, utilization, and scalability.

Culture & Benefits

• Full-time employment with medical, dental, and vision plans.
• 401(k) participation with company matching, ESPP, and EAP.
• Company-paid holidays, paid sick leave, vacation time, and applicable paid family and other leaves.
• Eligibility for a discretionary annual bonus, new-hire equity grant, and annual equity awards, subject to plan documents and award agreements.
• The role is associated with a United States workplace in San Jose, California.
