| Experience Level | Senior |
Requirements
- Bachelor’s or Master’s degree in Electrical Engineering, Electronics Engineering, or a related field.
- 5+ years of experience in signal integrity, high-speed PCB design, or related areas in hardware engineering. High speed Communication Buses (Ethernet, PCIe, SerDes…)
- Strong understanding of high-speed signal transmission principles, including impedance, crosstalk, noise, and signal attenuation.
- Proficiency in SI analysis tools such as HyperLynx, HFSS, CST, ADS, or similar industry-standard software.
- Hands-on experience with lab equipment such as oscilloscopes, VNAs, TDRs, and protocol analyzers.
- Expertise in PCB layout and design rules for high-speed, multi-layer boards.
- Familiarity with current SI trends, emerging technologies, and innovations in high-speed data transmission.
- Ability to contribute to process improvements and the development of new methodologies for signal integrity analysis.
Responsibilities
- Perform detailed signal integrity (SI) simulations using tools such as HyperLynx, HFSS, or CST to identify and resolve issues related to crosstalk, signal loss, reflections, and other performance degradations in high-speed designs.
- Analyze PCB layout designs to ensure optimal signal performance, providing feedback and recommendations to layout and hardware design teams.
- Collaborate with hardware engineers to optimize high-speed signal paths, ensuring adherence to specifications for interfaces like DDR, PCIe, USB, SerDes, and Ethernet.
- Evaluate and validate signal integrity for power delivery networks (PDN) to minimize noise, ground bounce, and power/ground integrity issues.
- Work closely with PCB layout, hardware, and mechanical teams to ensure design choices align with signal integrity best practices.
- Partner with systems engineering and software teams to ensure signal integrity across the entire product stack, from silicon to system integration.
- Develop and implement test strategies for verifying signal integrity on prototypes and final products using tools like oscilloscopes, vector network analyzers (VNA), and time domain reflectometry (TDR).
- Create and maintain signal integrity design guidelines, best practices, and checklists to support hardware engineers throughout the product development lifecycle.
- Lead the evaluation of new materials, design techniques, and tools that enhance signal integrity, proposing innovations that improve overall system performance.
- Diagnose and resolve SI issues during the bring-up phase of new products, ensuring minimal impact on time-to-market.
Preferred Qualifications
- Familiarity with current SI trends, emerging technologies, and innovations in high-speed data transmission.
