About Etched Etched is building the world’s first AI inference system purpose-built for transformers - delivering over 10x higher performance and dramatically lower cost and 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. Backed by hundreds of millions from top-tier investors and staffed by leading engineers, Etched is redefining the infrastructure layer for the fastest growing industry in history.

Job Summary As a Substrate IC Package Layout Design Engineer you will be responsible for the end-to-end design of complex IC substrate packages, supporting high-power consumption and high-speed signaling. The ideal candidate will have extensive experience with large substrate designs (>50mm), complex power delivery networks, and high-speed signaling solutions (up to and beyond 50GHz). You will work closely with silicon, signal integrity, power integrity, and system help co-design world class substates with OSAT providers. Intense focus on optimization for power delivery through substrate, pushing what’s possible.

Key Responsibilities

You may be a good fit if you have

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• 10+ years of experience in IC substrate layout design for high-performance processors or accelerators.
• Extensive experience with large substrate packages (>50mm) and complex high-density layouts.
• Proven experience with high-power (700W+) package designs and robust power delivery networks.
• Expertise in high-speed signaling design (>50GHz) and mitigating signal integrity challenges (crosstalk, reflections, impedance mismatches).

Benefits

• Medical, dental, and vision packages with generous premium coverage

• $500 per month credit for waiving medical benefits

• Housing subsidy of $2k per month for those living within walking distance of the office

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

• Various wellness benefits covering fitness, mental health, and more

• Daily lunch + dinner in our office

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 Row), 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.
