About Rambus
Rambus is a global company providing industry-leading memory interface chips and Silicon IP.
About the Role
Rambus is seeking a Signal Integrity (SI) Engineer to join the Memory Interface Chips Business Unit. This role involves developing next-generation DDR memory interface products operating at data rates exceeding 16 GT/s. This position is an excellent opportunity for new graduates to gain hands-on experience in high-speed link design, signal integrity analysis, power integrity analysis, package design, and system-level modeling. Rambus offers a flexible, hybrid work environment.
Key Responsibilities
- Support SI/PI analysis and simulations for memory interface products and associated package/board designs.
- Assist in channel modeling and simulation of high-speed DDR interfaces.
- Perform SI/PI studies to evaluate signal quality, jitter, crosstalk, return loss, eye diagram, and power delivery network (PDN) performance.
- Work with design, package, and validation teams to understand system requirements and simulation results.
- Correlate simulation data with laboratory measurements such as oscilloscope measurements, TDR measurements, and VNA measurements.
- Assist in developing simulation methodologies, automation scripts, and analysis flows.
- Document simulation results and present findings to cross-functional teams.
- Participate in silicon bring-up and debug activities when needed.
Requirements & Tech Stack
- Familiarity with circuit simulation tools such as SPICE, Keysight ADS, HFSS, PowerSI, and Ansys EM tools.
- Proficiency in at least one scripting language: Python, MATLAB, and Tcl.
- Ability to work effectively in a collaborative team environment.
Qualifications
- M.S. degree in Electrical Engineering (preferred) or B.S. degree in Electrical Engineering with strong academic performance.
- Coursework or research experience in one or more of: Signal Integrity, Power Integrity, Electromagnetics, High-Speed Digital Design, RF/Microwave Engineering, and Communication Systems.
- Strong understanding of: transmission line theory, S-parameters, reflection and termination, crosstalk mechanisms, jitter concepts.
- Strong analytical and problem-solving skills.
- Good written and verbal communication skills.
Preferred Qualifications
- Academic project, internship, or research related to DDR interfaces, SerDes, high-speed I/O, package design, and PCB design.
- Experience with ADS, HFSS, Q3D, PowerSI, and Cadence Allegro.
- Familiarity with measurement equipment such as oscilloscope, VNA, and TDR.
- Knowledge of equalization techniques such as FFE, DFE, and CTLE.
- Understanding of memory or semiconductor systems.
