Your Job
As a Signal Integrity (SI) Engineer, you will operate at the critical intersection of mechanical precision and electrical excellence. You will drive the development of next-generation interconnect solutions—including USB-C, HFM, HSAL-G and HS-Max—utilizing advanced 3D Electromagnetic (EM) simulation and high-frequency laboratory characterization. Your mission is to ensure Molex products deliver uncompromising signal integrity within the most demanding automotive and data center environments.
Our Team
You will be part of Global Signal Integrity team that's based out of Asia, North America and Europe, Molex is a global leader in providing the connectivity backbones of the modern world. In this role, you aren't just placing components; you are architecting the hardware that makes autonomous driving and hyperscale computing possible. You will collaborate with global experts in:
Automotive High-Speed Links: Designing the high speed data driven system for self-driving vehicles.
Next-Gen Protocols: Shaping the future of Automotive Ethernet and SerDes architectures.
Advanced Material Science: Exploring how dielectric properties and exotic plating's influence on high-frequency performance.
What You Will Do
3D EM Simulation & Virtual Prototyping
Full-Wave Modeling: Develop high-fidelity 3D models of connectors and cable terminations using Ansys HFSS or CST Studio Suite.
Optimization: Conduct "what-if" analyses on mechanical variables—such as pin geometry and shield spacing—to optimize impedance, return loss, and crosstalk.
Impedance Control: Identify and mitigate discontinuities within the connector pin-field and mating interfaces.
Lab Validation & Characterization
High-Frequency Measurement: Utilize VNAs and TDRs to characterize physical prototypes at frequencies of 20 GHz and beyond.
Advanced De-embedding: Apply AFR, TRL, or 2xThru de-embedding techniques to isolate connector performance from test fixture interference.
Correlation: Close the loop between virtual models and physical reality by validating simulation accuracy against empirical lab data.
Crosstalk Discovery & Mitigation
Aggressor-Victim Analysis: Perform deep-dive simulations to identify primary crosstalk contributors in high-density arrays.
Noise Calculation: Evaluate ICN (Integrated Crosstalk Noise) and Power Sum Crosstalk against IEEE 802.3 or OIF-CEI standards.
Pin-Map Optimization: Recommend optimized signal-to-ground ratios and G-S-S-G patterns to maximize isolation.
Data Automation & Strategy
Scripting: Leverage Python or MATLAB to automate the processing of massive Touchstone ($sNp$) datasets.
Compliance: Ensure designs meet or exceed industry specifications, including USB4, USCAR-2, LV214, Open Alliance, Automotive Ethernet and other standards.
Who You Are (Basic Qualifications)
Education & Experience Requirements:
PhD in Electrical Engineering, Physics, or Computer Engineering (RF/Microwave focus) + 5 years of experience.
Master's Degree in a related field + up to 8 years of experience.
Bachelor's Degree in a related field + 8 to 10 years of professional experience.
Core Competencies:
Analytical Rigor: A deep-seated desire to understand the "why" behind signal degradation and electromagnetic phenomena.
Communication: The ability to translate complex EM theory into actionable design guidance for mechanical teams and stakeholders.
Mobility: Willingness to travel up to 25% to support global projects.
What Will Put You Ahead
Expertise in Transmission Line Theory, S-parameters, and Smith Charts.
Mastery of simulation suites (Ansys HFSS, SI-Wave, ADS, CST).
Experience with Python (NumPy, Pandas, Matplotlib) for SI data analytics.
Practical experience in EMC/EMI testing and high-speed hardware debugging.
