What are SI (Supplemental Instructor)?

Supplemental Instructors (SI) are trained peer leaders who facilitate group study sessions to help students succeed in challenging courses. SI leaders attend lectures, collaborate with faculty, and then lead sessions where students review material, ask questions, and develop effective study strategies. The goal is to improve understanding of course content and foster collaborative learning among students. SI programs are commonly found in colleges and universities and are proven to boost academic performance.

What are some common challenges Si (Silicon) Process Engineers face when working in semiconductor fabrication plants?

Si Process Engineers in semiconductor fabrication often encounter challenges such as maintaining strict process control to ensure product yield and quality, troubleshooting equipment malfunctions, and optimizing complex manufacturing steps under tight deadlines. They must frequently collaborate with cross-functional teams, including design, equipment, and quality engineers, to resolve issues and implement process improvements. Continuous learning and adaptability are essential, as technology and industry standards evolve rapidly.

What are the key skills and qualifications needed to thrive as a Si, and why are they important?

I'm sorry, but 'Si' does not appear to be a recognized real-world professional occupation, so I cannot provide an accurate answer to this query.

What is the difference between Si vs Network Technician?

AspectSiNetwork Technician
Required CertificationsCompTIA Security+, Cisco CCNA, Network+CompTIA Network+, Cisco CCNA, Security+ (optional)
Work EnvironmentIT security, system monitoring, cybersecurityNetwork setup, troubleshooting, hardware installation
Industry UsageIT security firms, cybersecurity departmentsTelecom, enterprise IT, service providers
Common Search IntentSecurity-focused network rolesNetwork setup and troubleshooting

While both roles involve working with networks, Si primarily focuses on security and protecting systems, whereas Network Technicians handle the installation, maintenance, and troubleshooting of network hardware and infrastructure. Understanding these differences helps employers and job seekers target the right skills and certifications for each role.

Job description

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 Signal Integrity and Power Integrity (SI/PI) Engineer to join our platform electrical engineering team. In this role, you will own the SI/PI methodology for high-speed PCB and system designs - from early architecture through final release - ensuring electrical margins are met across interfaces running at multi-gigabit data rates.
Key Responsibilities
  • Perform pre- and post-layout SI simulations for high-speed serial interfaces including PCIe Gen5/Gen6, 112G/224G Ethernet.
  • Conduct channel analysis and link budget calculations; define topology constraints, trace geometry, stack-up requirements, and via optimization guidelines for PCB designers.
  • Develop and maintain COM, IBIS, S-parameter, and SPICE models; correlate simulation results against lab measurements.
  • Execute power delivery network (PDN) design and analysis: target impedance profiling, decoupling capacitor selection, AC/DC power analysis, and IR-drop simulation.
  • Drive DFI and design rule checks for SI/PI compliance; work with layout teams in Cadence Allegro / Sigrity or Ansys SIwave.
  • Collaborate with PCB design and layout engineers, and ASIC teams to define and review design guidelines early in the product lifecycle.
  • Support bring-up, debug signal quality issues, and document root-cause findings with clear corrective actions.
  • Develop and maintain simulation-to-hardware correlation databases to continuously improve modelling 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 SI/PI experience on high-speed designs (>1 Gbps serial links or DDR4/5 and HBM3/4 memory interfaces).
  • Proficiency with industry SI/PI EDA tools (Cadence Sigrity, Ansys SIwave/HFSS, Keysight ADS, or equivalent).
  • Strong understanding of transmission line theory, return-loss, insertion-loss, crosstalk, eye-diagram analysis, and jitter decomposition.
  • Experience with PDN modelling, target impedance methodology, and DC IR analysis.
  • Working knowledge of multi-layer PCB stack-up design and controlled-impedance trace routing.
  • Hands-on lab skills: S-parameter measurements with VNA, time-domain reflectometry (TDR), BERT operation, and oscilloscope probing techniques

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 scripting automated SI/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 $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 and dinner in our office
  • Unlimited compute budget subject to ROI justification

How we're different
Etched believes in the Bitter Lesson. We are the first inference-focused frontier AI system, betting early on transformer and transformer-like architectures and on increasing model sizes. Our addressable market is the entirety of inference, unlike many of our competitors.
We are a fully in-person team in San Jose and Taipei, 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.
