Director of Memory Design

Acceler8 Talent; San Francisco (CA); On-site; USD 250,000 - 500,000; Full time

Job summary

Acceler8 Talent is partnering with a startup designing a cutting-edge 3D-memory-integrated AI accelerator platform to hire an experienced, visionary Director of Memory Design. In this role, you’ll architect and implement a custom memory controller, owning the access path from memory requests to data delivery, and extending an existing controller for custom requirements.

You will design memory-access pipelines, optimize low-latency paths and evaluate scheduling, bandwidth, latency, and power

Qualifications

• Direct memory-controller or substantial memory-subsystem architecture and RTL-design ownership.
• Strong DDR/LPDDR/GDDR understanding and deep memory request/data-pipeline reasoning.
• Ability to make concrete VLSI tradeoffs and debug timing/structural design issues.
• 15-20 years of relevant experience; hands-on technical leadership is central.
• HBM2/2E/3 base-die design, custom DRAM interfaces and 3D/TSV integration.

Responsibilities

• Own custom controller architecture and SystemVerilog RTL from design through SoC integration and tapeout.
• Design memory-access pipelines and low-latency paths; evaluate scheduling, queue depth and bandwidth/latency/power tradeoffs.
• Adapt controller functions such as scheduling, ECC, refresh, training and power management to interface requirements.
• Optimize custom DRAM/3D-memory connectivity, collaborating with memory partners on TSV fabrics and interface requirements.
• Drive lint, CDC/RDC, equivalence, synthesis, constraints and timing convergence with physical-design and verification teams.
• Define/review verification plans, maintain technical documentation and mentor engineers.

What You Bring:

• Direct memory-controller or substantial memory-subsystem architecture and RTL-design ownership.
• Strong DDR/LPDDR/GDDR understanding and deep memory request/data-pipeline reasoning. SystemVerilog, front-end convergence and scripting; multiple successful silicon tapeouts.
• Ability to make concrete VLSI tradeoffs and debug complex timing and structural design issues.
• 15-20 years of relevant experience; hands-on technical leadership is central.
• HBM2/2E/3 base-die design, custom DRAM interfaces and 3D/TSV integration. C ontroller performance modeling, scheduler evaluation and queue-depth analysis.
• AI inference memory patterns, CXL and multi-die/chiplet integration.
• Low-power techniques and high-speed memory-interface DFT.
