Signal Integrity Engineer

What You'll Do:

In the signal integrity (SI) engineer role, you will have the opportunity to be a part of engineering team that designs Advanced Security Hardware Appliances. We are looking for candidates who strive in a fast-paced start-up like environment. You will be part of a dedicated team; open communications, empowerment, innovation, teamwork and customer success are the foundations of the team. The ideal candidate has a can-do attitude with an eagerness to learn and solve problems that are of the most challenging kind. We are looking for a motivated Signal Integrity Engineer to contribute to the development of our next generation products. 

 

Primary areas of responsibility:

  • Working directly with the Hardware design team to evaluate design tradeoffs and optimize design performance / risk / cost / manufacturability
  • Drive next generation SerDes IP characterization
  • Design and analysis of multi-gigabit serial links and their compliance to standards
  • Electromagnetic modeling of complex 3-dimensional structures
  • Perform pre- and post-route signal integrity analysis of PCB designs
  • Work closely with the PCB CAD team, generating and verifying PCB layout rules and supporting placement feasibility studies
  • Performing DDR4/DDR5 static timing and signal integrity analysis
  • Modeling and analyzing power delivery networks
  • Performing physical measurements to collect data for design validation and simulation correlations
  • Driving methodology improvements and automation - growing performance and efficiency 
  • Development simulation tools with EDA vendor(s) whenever needed for analysis
  • Mentor junior engineers and interns
 

Who You'll Work With:

You will be part of a dedicated team; open communications, empowerment, innovation, teamwork and customer success are the foundations of the team! You will be primarily working with teams that do hardware and software development, design verification testing, manufacturing new product introduction (NPI) as well as our contract manufacturers. In addition, you will work closely with additional SI engineers from the Cisco core hardware group, to support our product development.

 

Who You Are:

  • Self-motivation, strong teamwork, strong communication skills and out of the box thinking with the strong desire to innovate are essential.
  • Working experience with high speed NRZ and PAM4 SerDes, PLLs, CDR and FEC
  • Hands on experience with CPU and FPGA development focused on SerDes, DDR4/DDR5 and I/O IP selection, package design and simulation, power integrity
  • Solid knowledge of the IEEE 802.3 and OIF specifications for 25Gbps and 56Gbps SerDes Interfaces
  • Hands on experience with a broad range PCB materials, understanding cost/performance trade offs
  • Knowledge of DDR4/DDR5 simulation methodology and timing analysis
  • Working knowledge of system level power integrity and budgeting (DC, AC, transient analysis)
  • Well versed with 3-D field solvers
  • In depth understanding of electromagnetic theory is required
  • Working knowledge of AMI models and tools (SiSoft QCD and ADS)
  • Strong lab skills and measurement experience are required (VNA, TDR, Real Time Scope, BERT)
  • Strong tools knowledge (HFSS, ADS, SiSoft QCD and QSI, Cadence PowerSI/DC, Allegro, Simbeor, HSpice)
  • Generating the routing requirements and electrical margins for specific interfaces and verifying their correctness
  • Ability to define a project schedule and requirements, then deliver to that schedule
 

Educational Background:

PhD/MSEE combined with 4-8 years of related experience, or BSEE combined with 7-10+ yrs related experience.
