Senior Principal SI Engineer — High-Speed Interconnects

Amphenol ICC; Santa Clara (CA); On-site; USD 120,000 - 170,000; Full time

Job summary

Amphenol Communications Solutions, a division of Amphenol Corporation, seeks an experienced SI engineer in the Santa Clara area to lead high-speed interconnect development and validation. The role involves lab work, multi-disciplinary collaboration, and customer support for complex signal integrity challenges.

You will drive architecture decisions, mentor engineers, and coordinate global ramp-up activities with offshore and domestic teams to ensure robust product performance across applications.

Qualifications

• BS in Electrical Engineering. MS or PhD strongly preferred
• Deep understanding of electromagnetic principles for digital signal integrity
• Experience with SI and EM simulation tools such as Ansys HFSS and Designer, CST Microwave
• Experience with SI measurements and debugging using TDR, VNA, pattern generators, error detectors, and similar equipment
• Hands on experience with frequency domain and time domain component and circuit characterization including understanding of test and calibration techniques
• Experience in component design and application of high speed cables or connectors into communications equipment is a plus
• Experience with MATLAB, ADS, and HSPICE is a plus
• Proven track record of leading SI development for advanced cable or connector products
• Ability to drive architecture, influence material and process selection, and provide senior level technical direction across programs
• Strong ability to independently lead SI investigations, manage multi site collaboration, and support lab based measurement and debug activities

Responsibilities

• Design, simulation, characterization, and application of high speed electrical cable assemblies
• Provide SI technical leadership, own major engineering projects, and mentor new SI hires
• Work regularly in the west coast office for lab measurements, validation, and debugging. Support in setting up the local SI lab including identifying and purchasing required equipment
• Component development and customer support during new product introduction
• Share knowledge and pursue continuous improvement in methods and workflows
• Collaborate with multi disciplinary teams in the development of next generation high speed I/O interconnect products
• Provide solutions to customers across many sectors with their high speed data transmission needs, identifying and resolving signal integrity issues
• Engage directly with customers to debug system level SI issues and answer high level technical questions
• Own project execution by ensuring all tasks are completed and by driving progress across functions, not by delegating responsibility upward
• Support Sales and Applications Engineers to develop strategies for product break in at existing and new accounts based on SI and electrical engineering expertise
• Support global factories for production ramp up, including methods, build experiments, measurement development, and establishing test limits
• Travel 10 to 20 percent, primarily to Nashua to coordinate with the design team. Occasional customer visits as engineering support but not as the primary customer contact
• Mentor SI engineers and influence cross functional engineering processes and standards
