Employer immigration record

from this employer's Department of Labor filings

Files H-1B transfers

10 transfer filings in the last year, covering 10 workers. Median labor-condition decision: 28 days. An employer that already files transfers is one that can take over an existing H-1B.

Sourced from Department of Labor LCA, PERM and prevailing-wage disclosure data. Employer matching is by name, so figures may be split across an employer's legal entities. Absence of a filing means none appears in our copy of the data, not that none exists.

About the role

  • This position offers a unique opportunity to solve complex interactions across digital, analog and photonics domains while meeting stringent signal integrity goals.

Responsibilities

  • Analyze high-speed channel characteristics including S-parameters, insertion loss, return loss, and crosstalk to evaluate and optimize signal quality.
  • Perform signal integrity analysis and simulations (eye diagram analysis, jitter analysis, equalization) by adapting existing practices and procedures to evaluate design choices.
  • Collaborate with cross-functional teams including hardware designers and PCB layout engineers working on individual and team projects that impact the broader engineering function.
  • Perform detailed signal integrity measurements and characterization using lab equipment (oscilloscopes, network analyzers, TDRs, VNA) to validate design performance and troubleshoot ill-defined issues.
  • Participate in signal integrity design reviews, presenting findings and suggesting creative variations in approach to ensure adherence to design specifications.
  • Document and communicate signal integrity analysis results and design guidelines to stakeholders, adapting communication style depending on the audience.

Requirements

  • B.S. or M.S. degree in Electrical Engineering or relevant field with a minimum of 5 years of related experience.
  • Proficiency in using simulation and analysis tools for signal integrity, including Ansys Siwave, HFSS & Keysight ADS.
  • Strong understanding of transmission line theory, impedance matching, and equalization techniques.
  • Knowledge of signaling protocols for high-speed interfaces, including SerDes, UCIE, etc.
  • Experience with PCB design and layout considerations for high-speed interfaces (layer stack-up, routing, and via design).
  • Proficiency in using lab equipment for signal measurement and characterization.
  • Ability to write scripts to automate the simulation flow (Python, JavaScript, Ocean scripts, or SKILL).
  • Robust professional and specialized knowledge in signal integrity analysis for high-speed interfaces.
  • Ensure robust signal integrity and timing performance for lower-speed critical interfaces and control buses, such as system clocks, SPI, and I2C.

Nice to have

  • Strong problem-solving and debugging skills for signal integrity-related issues.
  • Understanding of CMOS process technologies and their impact on signal integrity.
  • Ability to work independently, utilizing best judgment to select appropriate courses of action, with work reviewed at critical checkpoints.

Compensation

  • total compensation goes beyond base salary, it also includes a new hire equity grant, annual performance-based equity, and other rewards that recognize your impact and contribution.
  • $157,000 - $176,000 USD

Benefits
