What is a Si Pi engineer?

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?

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

Hardware Engineering is an innovative and collaborative group of electrical, mechanical, reliability, software and vehicle engineers. We design, build, and perfect the products which are the eyes and ears of Waymo's autonomous driving technology, and integrate those products into vehicle platforms. We're seeking curious and talented teammates to keep us moving in the right direction.

This role follows a 100% onsite work schedule and you will report to a Hardware Engineering Manager

You will:

  • Lead all stages of project planning and development by owning SI/PI for products and sub-systems.
  • Establish comprehensive SI/PI guidelines and stack-up specifications through feasibility studies; collaborate with cross-functional teams to resolve SI/PI challenges.
  • Audit layout routing and component placement for all interfaces to maximize SI/PI performance.
  • Perform SIPI simulation for PCB, connectors, cabling and sign-off designs
  • Measure and correlate with simulation models, enhancing model accuracy.
  • Research and integrate advanced SI/PI technologies to improve simulation efficiency, consistency, and precision.

You have:

  • BS degree in Electrical Engineering with 5+ years relevant working experience
  • Ability to perform system level SIPI design, modeling and optimization with simulation softwares such as  HFSS, SIwave, PowerSI, ADS, HSPICE
  • Familiarity with lab equipment such as oscilloscope, VNA, and TDR
  • Demonstrated experience with simulation-to-measurement correlation
  • Hands-on capability in lab environments to debug and resolve SI/PI-related issues
  • Excellent communication skills with experience to collaborate with internal and external teams

We prefer:

  • M.S.E.E. with 3 years of relevant industry experience, or a recent Ph.D. with a specialization in SIPI
  • Familiarity in one or more of the following areas: SERDES, SoC Power Integrity (PI) with VR modeling, or LPDDRx interfaces
  • Experience in root-cause analysis and debugging of real-world SI/PI hardware issues
  • Streamlined SI/PI workflows through custom tool automation and scripting [Python/Tcl]
  • Familiar with automotive-grade interfaces such as xGBase-T1, CAN/CAN-FD, LVDS, GMSL
  • Experience with DoE simulation for high-volume production intended designs
