Job Summary
Lead the design, development, and implementation of electrical systems and circuits, including creating schematics, bills of material, and diagrams for various applications. Research system ideas, develop plans, and validate performance through testing, simulation, and measurement using tools like ADS and ANSYS HFSS. Provide technical leadership to a team of engineers, review customer requirements, and coordinate deployment efforts while promoting industry best practices. Liaise with suppliers, customers, and internal teams to solve complex signal integrity challenges and recommend system modifications.
Required Qualifications
- Experience in PCB design fundamentals, including single-ended and differential signals
- Proficient in managing signal integrity challenges such as signal loss, impedance control, and crosstalk (near-end and far-end)
- Experience with single-ended and differential signaling up to 50Gbps
- Skilled in working with component models (Touchstone files) and cascading them to create comprehensive system models for simulation
- Experienced in simulating digital interfaces (FPGA to DRAM, SERDES) and analog paths (PCB, connector, cable from signal driver to DUT)
- Proficient with 2D and 3D simulation tools (e.g., ADS, ANSYS HFSS, Sigrity)
- Capable of electrical length calculations for signal matching
- Familiar with interpreting signals in both frequency (S-parameter) and time domains to assess suitability for applications
- Proficient in generating and interpreting data-eye diagrams up to 50Gbps for NRZ and PAM4
- Proficient with Allegro or similar layout tools and schematics
- Expertise in PCB stack-up design, considering fabrication limitations and cost trade-offs
- Experience with high-frequency board materials
- Significant experience in measuring signal performance in the lab, including TDR and VNA measurements
- Able to develop test fixtures, from custom test boards to ad hoc probing solutions for troubleshooting
- Experienced in balancing cost vs. performance tradeoffs in signal path design
- Experience with flex circuit design for high-speed signaling
- 4 to 6 years in a similar role or industry
- Bachelor degree or consideration of an equivalent combination of education and experience
