About Etched

Etched is building AI chips that are hard-coded for individual model architectures. Our first product (Sohu) only supports transformers, but has an order of magnitude more throughput and lower latency than a B200. With Etched ASICs, you can build products that would be impossible with GPUs, like real-time video generation models and extremely deep & parallel chain-of-thought reasoning agents.

Job Summary

We’re seeking a skilled Distinguished DRAM Engineer to advance our memory systems. You will collaborate with design and verification teams to perform DRAM simulations, validate SoC memory integration, and oversee HBM silicon and package testing. Additionally, you will develop and implement advanced debugging methodologies and ensure our memory solutions adhere to stringent performance and reliability specifications.

Key responsibilities

  • Perform Post-Si validation and electrical characterization.

  • Work with Memory Controller, DDRPHY/HBMPHY, and DRAM vendors to optimize main memory performance and power.

  • Perform DRAM simulations to ensure they meet Etched's requirements.

  • Validate SoC memory controller and PHY integration and help verification of features in simulation and emulation.

  • Oversee internal and external HBM silicon and package level testing.

  • Develop bring-up and debug methodologies for DDR and HBM interfaces.

  • Collaborate with design, verification, and integration engineers for performance validation.

You may be a good fit if you have

  • Bachelor’s degree with a minimum of 10 years relevant industry experience. Strong candidates may also have Master's or PhD Degrees with 5 years of relevant industry experience.

  • Deep knowledge of DRAM architectures and memory organization.

  • Experience with DRAM simulation and interface verification (HBM2E/HBM3 PHY, Memory Controller).

  • Strong understanding of memory test patterns and DRAM reliability.

  • Experience with HBM2E/3/3E/DDR5/LPDDR4+ based products.

  • Understanding of computer architecture and micro-architecture.

  • Programming experience in C/C++ and Python.

  • Excellent hardware and software debugging skills.

  • Strong teamwork and interpersonal skills.

Benefits

  • Full medical, dental, and vision packages, with 100% of premium covered

  • Housing subsidy of $2,000/month for those living within walking distance of the office

  • Daily lunch and dinner in our office

  • Relocation support for those moving to San Jose (Santana West)

How we’re different

Etched believes in the Bitter Lesson. We think most of the progress in the AI field has come from using more FLOPs to train and run models, and the best way to get more FLOPs is to build model-specific hardware. Larger and larger training runs encourage companies to consolidate around fewer model architectures, which creates a market for single-model ASICs.

We are a fully in-person team in San Jose (Santana West), and greatly value engineering skills. We do not have boundaries between engineering and research, and we expect all of our technical staff to contribute to both as needed.
