About Etched

Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference. 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

We are looking for a Power Integrity (PI) Engineer to join our platform electrical engineering team. In this role, you will own the power integrity methodology for high-power PCB and system designs — from early architecture through final release — ensuring robust power delivery to high-performance ASICs and supporting components across all operating conditions.

Key Responsibilities

- Perform pre- and post-layout PDN analysis for high-current ASIC power rails: target impedance profiling, decoupling capacitor selection and placement optimization, and plane resonance analysis.

- Execute DC IR-drop and current density simulations; define copper weight, plane shapes, via stitching, and layer allocation requirements for PCB designers.

- Conduct AC impedance analysis from VRM output through package and die, including ESR/ESL modeling of the full decoupling network.

- Develop and validate VRM models; analyze load transient response, AVP/load-line behavior, and multiphase converter performance against ASIC power specifications.

- Perform power-plane thermal co-simulation and work with mechanical teams on thermal-electrical tradeoffs for high-current delivery.

- Drive design rule checks for PI compliance; work with layout teams in Cadence Allegro / Sigrity PowerDC/PowerSI or Ansys SIwave.

- Collaborate with power design, PCB layout, and ASIC/package teams to define power delivery architecture and review guidelines early in the product lifecycle.

- Support bring-up, debug rail-level issues (droop, ripple, transient excursions), and document root-cause findings with clear corrective actions.

- Develop and maintain simulation-to-hardware correlation databases to continuously improve PDN modeling accuracy.

You may be a good fit if you have (Must-have qualifications)

- B.S. or M.S. in Electrical Engineering or a closely related discipline.

- 5+ years of hands-on PI experience on high-current, high-performance designs (ASIC/CPU/GPU power delivery, server boards, or accelerator platforms).

- Proficiency with industry PI EDA tools (Ansys SIwave, Cadence Sigrity PowerDC/PowerSI/OptimizePI, or equivalent).

- Strong understanding of target impedance methodology, decoupling network design, plane resonances, and anti-resonance mitigation.

- Experience with DC IR-drop analysis, current density limits, and via/plane current-carrying capacity.

- Working knowledge of VRM fundamentals: buck converter operation, multiphase design, transient response, and load-line/AVP concepts.

- Working knowledge of multi-layer PCB stack-up design and power plane allocation strategies.

Strong candidates may also have experience with (Nice-to-have qualifications)

- Prior work in data center, AI/ML accelerator, networking, or high-performance computing (HPC) hardware environments.

- Experience with vertical power delivery, high-current lateral delivery tradeoffs, or 48V-to-point-of-load architectures.

- Package-level PDN co-analysis and experience working with die/package power models from ASIC teams.

- Experience scripting automated PI simulation flows using Python or MATLAB to reduce manual simulation turnaround time.

Benefits

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

- $500 per month credit for waiving medical benefits

- Housing subsidy of $2,500 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 and dinner in our office

- Unlimited compute budget subject to ROI justification

How we’re different

Etched believes in the Bitter Lesson http://www.incompleteideas.net/IncIdeas/BitterLesson.html. We are the first inference-focused frontier AI system. Our addressable market is the entirety of inference, unlike many of our competitors.

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 and work across disciplines as needed.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
