About the role
- This position offers a unique opportunity to solve complex interactions across digital, analog and photonics domains while meeting stringent signal integrity goals.
Responsibilities
- Analyze high-speed channel characteristics including S-parameters, insertion loss, return loss, and crosstalk to evaluate and optimize signal quality.
- Perform signal integrity analysis and simulations (eye diagram analysis, jitter analysis, equalization) by adapting existing practices and procedures to evaluate design choices.
- Collaborate with cross-functional teams including hardware designers and PCB layout engineers working on individual and team projects that impact the broader engineering function.
- Perform detailed signal integrity measurements and characterization using lab equipment (oscilloscopes, network analyzers, TDRs, VNA) to validate design performance and troubleshoot ill-defined issues.
- Participate in signal integrity design reviews, presenting findings and suggesting creative variations in approach to ensure adherence to design specifications.
- Document and communicate signal integrity analysis results and design guidelines to stakeholders, adapting communication style depending on the audience.
Requirements
- B.S. or M.S. degree in Electrical Engineering or relevant field with a minimum of 5 years of related experience.
- Proficiency in using simulation and analysis tools for signal integrity, including Ansys Siwave, HFSS & Keysight ADS.
- Strong understanding of transmission line theory, impedance matching, and equalization techniques.
- Knowledge of signaling protocols for high-speed interfaces, including SerDes, UCIE, etc.
- Experience with PCB design and layout considerations for high-speed interfaces (layer stack-up, routing, and via design).
- Proficiency in using lab equipment for signal measurement and characterization.
- Ability to write scripts to automate the simulation flow (Python, JavaScript, Ocean scripts, or SKILL).
- Robust professional and specialized knowledge in signal integrity analysis for high-speed interfaces.
- Ensure robust signal integrity and timing performance for lower-speed critical interfaces and control buses, such as system clocks, SPI, and I2C.
Nice to have
- Strong problem-solving and debugging skills for signal integrity-related issues.
- Understanding of CMOS process technologies and their impact on signal integrity.
- Ability to work independently, utilizing best judgment to select appropriate courses of action, with work reviewed at critical checkpoints.
Compensation
