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 Signal Integrity / Power Integrity Intern, you will help design and validate the next generation of high-performance AI systems. You will work closely with package, PCB, ASIC, and system engineers to analyze high-speed interfaces, extract channel models, and improve signal quality across our accelerator platforms.
This role provides hands-on experience with industry-leading tools and real-world challenges involving PCIe, Ethernet, high-speed SerDes channels, advanced packaging, and multi-board systems.
Key Responsibilities
Signal Integrity Analysis
Perform channel analysis for high-speed interfaces including PCIe, Ethernet, and other SerDes links.Extract and validate S-parameter models from package and PCB layouts.Analyze insertion loss, return loss, impedance discontinuities, and crosstalk.Generate channel compliance reports and support design reviews.Modeling & Simulation
Build and validate 3D electromagnetic models using Ansys HFSS.Develop board and package channel models from ECAD design databases.Correlate simulation results with measurements and lab data.Support mixed package-board channel simulations and optimization.Design Collaboration
Partner with PCB layout, package, hardware, and ASIC teams to improve signal integrity.Identify root causes of channel degradation and propose design improvements.Contribute to SI design guidelines and best practices.Representative Projects
Extracting S-parameter models from package and board designs for PCIe channels.Building HFSS models of high-speed breakout regions and BGA transitions.Performing channel compliance analysis for Ethernet links.Investigating impedance discontinuities and optimizing via structures.Developing automated workflows for SI simulation and report generation.You May Be a Good Fit If You Have
Progress toward a BS, MS, or PhD in Electrical Engineering, Computer Engineering, or a related field.Coursework or project experience in signal integrity, electromagnetics, RF, microwave engineering, or high-speed digital design.Familiarity with transmission line theory and S-parameters.Understanding of PCB stackups, routing, and high-speed design fundamentals.Strong analytical and debugging skills.Excellent communication and collaboration skills.Strong Candidates May Also Have
Experience with Ansys HFSS, SIwave, ADS, CST, or similar simulation tools.Experience with PCIe, Ethernet, DDR, or other high-speed interfaces.Familiarity with Allegro, APD, ODB++, IPC2581, or other ECAD databases.Experience processing Touchstone files and channel metrics.Python scripting for simulation automation and data analysis.Experience with laboratory measurements using VNAs, oscilloscopes, or TDR equipment.We encourage you to apply even if you do not believe you meet every qualification.

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 West San Jose, 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.
Discover Other Areas
Understand the scope of work, key skills, and tools used in different career areas.
About Customer Service
The Customer Service / Client Relations area is essential for ensuring customer satisfaction, retention, and a good relationship. Professionals in this field are the primary interface for communication, handling inquiries, requests, feedback, and ensuring a high-quality day-to-day experience. Skills in communication, problem-solving, empathy, and patience are indispensable.
About Cloud Solutions
The Cloud Solutions area is responsible for designing, implementing, and managing cloud infrastructure and services (AWS, Azure, GCP) for companies. Cloud professionals architect scalable, secure, and cost-optimized solutions, from data center migrations to serverless and multi-cloud architectures.
Key skills include IaC (Terraform, CloudFormation), containers (Docker, Kubernetes), serverless (Lambda, Cloud Functions), managed databases (RDS, DynamoDB, BigQuery), cloud networking (VPC, CDN, load balancer), and security (IAM, WAF, KMS). Knowledge of FinOps, cloud governance, and AWS/Azure/GCP certifications is a differentiator.
Cloud Solutions professionals in technology companies are highly valued, especially those who master multi-cloud architectures, FinOps, and can optimize costs while maintaining performance and security. The field offers opportunities from cloud engineer to cloud solutions architect, head of cloud, and chief cloud architect.
About Sales
The Sales area is responsible for generating revenue and expanding the customer base. B2B and B2C sales professionals are fundamental for sustainable growth of any organization.
Key skills include prospecting, negotiation, CRM (Salesforce, HubSpot), sales enablement, and value consulting. The consultative and data-driven approach is increasingly valued.
Consultative sellers and senior Sales Managers have very high earning potential, with OTE (On-Target Earnings) that can exceed monthly salaries in technology companies.
About Content Writer
The Content Writer is the professional responsible for creating quality written content for websites, blogs, social media, and other digital platforms. They combine writing skills with content strategy and SEO to attract, engage, and convert audiences.
Key skills include blog content creation, landing pages, newsletters, social media content, keyword research, content strategy, editorial calendar, and SEO writing. Knowledge of WordPress, Surfer SEO, Ahrefs, and analytics tools is a differentiator.
Content Writers in technology companies are highly valued, especially those who can create accessible technical content, evergreen content, and content that generates organic traffic. The field offers opportunities from junior content writer to head of content, with a focus on quality, strategy, and content performance.
About Talent Acquisition
Talent Acquisition is the strategic area responsible for attracting, selecting, and hiring the best professionals for the organization. Unlike traditional recruitment, TA acts as a strategic business partner, aligning talent acquisition with the company's long-term objectives.
Key skills include advanced sourcing, employer branding, labor market analysis, talent pipeline management, and candidate experience. Tools like LinkedIn Recruiter, ATS (Greenhouse, Lever, Ashby), and assessment platforms are essential.
