Signal Integrity Engineer

Company: Teradyne, Inc.
Location: San Jose
Posted on: June 8, 2021

Job Description:

We are the global test and automation specialists, powering next-generation technologies through sophisticated solutions. Behind every electronic device you use, Teradyne's test technology ensures your device works right the first time, every time! Our portfolio of automation solutions help manufacturers to develop and deliver products quickly, efficiently and cost-effectively. Together, Teradyne companies deliver manufacturing automation across industries and applications around the world!.

Organization & Role

The Teradyne Hardware Engineering team is looking for a highly-motivated, energetic, technically driven Hardware Engineer to focus on the development of hardware systems for products within the Semiconductor Test division. Development occurs in a dynamic and challenging multi-site development environment.

Responsibilities

This person will play a critical role in the planning of digital PCB designs, simulation, lab verification, and troubleshooting signal integrity issues on completed designs. They will also be expected to help with design review of critical PCBs for signal integrity concerns. Good communications skills and ability to work with physically dispersed teams is a strong requirement.

Please note, Teradyne is not providing sponsorship for this role at this time. Thank you!

Basic Qualifications & Skills

The successful candidate will have 10+ years experience with High Speed Signal Delivery Design and Evaluation. This includes both signal integrity within a PCB and off the board (board to board connectors, ribbon cables, coaxial cable, etc.).

  • PCB design fundamentals (single ended and differential signals)
  • Signal loss
  • Impedance control
  • Crosstalk (near end and far end)
  • Familiar with single-ended and differential signaling up to 50Gbps
  • Familiar working with component models (touchstone files) and cascading models to generate complete system models for simulation
  • Simulation of digital interfaces (examples would be FPGA to DRAM, SERDES interfaces)
  • Simulation of analog paths through a combination of PCB, connector, and cable (examples would be signal driver to DUT)
  • Very familiar with 2D and 3D simulation tools (examples include ADS, ANSYS HFSS, Sigrity)
  • Electrical length calculations for signal matching
  • Familiar with looking at signals in both frequency (S-parameter) and time domain and understand how to interpret results when it comes to suitability for a particular application.
  • Familiar with generating and interpreting data-eye diagrams up to 50Gbps: NRZ and PAM4
  • Familiar with Allegro or similar layout tool and schematics:
  • PCB Stackup design and familiar with fabrication limitations and cost trade-offs
  • High Frequency board material experience
  • Significant experience with measuring signal performance in the lab: TDR measurements and VNA measurements
  • Able to develop test fixtures for making measurements (both custom design test boards as well as making "ad hoc" probing solutions to troubleshoot existing PCBs)
  • Familiar with the cost vs performance tradeoffs when designing signal paths as cost is key design constraint
  • Experience with flex circuit design for high speed signaling

Education

  • BSEE, MSEE, PhD or equivalent
