What are Si Pi Engineers?

Si Pi Engineers, also known as Signal Integrity and Power Integrity Engineers, are professionals who specialize in ensuring that electronic systems, especially those involving high-speed signals and complex power delivery networks, function correctly and reliably. They analyze, design, and troubleshoot circuits to minimize signal degradation, interference, and power delivery issues in printed circuit boards (PCBs) and integrated circuits. Their work is critical in industries such as telecommunications, data centers, consumer electronics, and automotive electronics, where high-speed data transfer and stable power are essential.

What is the difference between Si Pi Engineer vs PCB Design Engineer?

AspectSi Pi EngineerPCB Design Engineer
CredentialsBachelor's in Electrical Engineering or related; certifications like IPC CID or IPC CID+Bachelor's in Electrical Engineering, Electronics, or related; certifications like IPC CID or IPC CID+
Work EnvironmentElectronics manufacturing, semiconductor, or embedded systems companiesElectronics design firms, manufacturing, or consulting companies
Industry UsageUsed in semiconductor, embedded systems, and IoT industriesCommon in consumer electronics, industrial equipment, and communication devices

Both Si Pi Engineers and PCB Design Engineers often hold similar credentials and work in electronics-related industries. However, Si Pi Engineers focus more on signal integrity and power integrity within integrated circuits, while PCB Design Engineers specialize in designing printed circuit boards. Understanding these distinctions helps clarify career paths and job expectations in electronics design and manufacturing.

What are some common challenges faced by Si Pi Engineers when collaborating with cross-functional teams?

Si Pi Engineers often work closely with hardware designers, PCB layout engineers, and system integrators to ensure signal and power integrity across complex electronic systems. A common challenge is effectively communicating technical requirements and constraints, as not all team members may have a deep understanding of SI/PI principles. Additionally, balancing performance, cost, and manufacturability while resolving issues such as crosstalk, noise, and voltage fluctuations can require creative problem-solving and strong teamwork. Regular design reviews and open communication channels help mitigate these challenges and lead to successful project outcomes.

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

To thrive as a Si Pi (Signal Integrity/Power Integrity) Engineer, a strong background in electrical engineering, circuit design, and high-speed signal analysis is essential, usually supported by a relevant engineering degree. Familiarity with simulation tools such as HyperLynx, Ansys SIwave, and Cadence, along with experience in PCB layout and measurement instruments like oscilloscopes and VNAs, is typically required. Analytical thinking, problem-solving, and effective communication are vital soft skills for collaborating across design and manufacturing teams. These competencies ensure reliable high-speed electronic systems, minimize signal loss, and prevent power distribution issues, which are critical for product performance and integrity.

Job description

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
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 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 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.
