System high-speed I/O validation Engineer - Apple Mac
Cupertino, California, United States
Hardware
This is a system-level validation role within the Mac Hardware organization, specifically in the SerDes I/O validation for Mac Platforms. The candidate’s responsibilities include setting up and executing I/O electrical compliance flow bringups for Mac platforms, testing Mac platforms to stress-test I/Os in systems, and collecting metrics. Additionally, they will be involved in high-speed validation and electrical compliance testing of I/Os for form-factor systems. The candidate will collaborate closely with cross-functional teams, such as system signal integrity, silicon design, or system design teams. While the role primarily focuses on lab validation activities related to system-level signal integrity, there are also validation responsibilities for high-speed cables and fixtures. Come join us!
Description
In this role you will:
Execute high-speed serial I/O electrical compliance tests
Organize compliance data reports for comparison against specs and approval by certification orgs
Troubleshoot and triage issues with compliance test hardware, fixtures, software, and the DUT (Device Under Test)
Failure analysis feedback for iterative HW design/SW Tunable improvements
Define and develop methods for stress testing to identify design operating limits of Serial IOs post system integration
Validation of high-speed fixtures, connectors, cables, and Mac IOs
Develop python based scripts to speed up automation and data collection
Minimum Qualifications
- M.S Degree with 2~3 years relevant work experience
- Familiarity with all aspects of Signal Integrity for high speed SerDes, parallel bus, single ended signaling
- Ability to execute on channel analysis with Signal integrity EDA
- Measurement expertise with frequency and time domain tools (VNA, TDR) including calibration methods
Key Qualifications
Preferred Qualifications
- M.S. Degree with 5 to 10 years of relevant work experience.
- Deep knowledge of system-level Serdes design and analysis skills is required. This includes understanding of transmitter and receiver equalization methods (such as FFE, CTLE, DFE, VGA gain), CDR behaviors and modeling, link training algorithms, and eye margining tools.
- Serial bus expertise includes knowledge of the specifications of PCIe, USB, DisplayPort, HDMI, and Thunderbolt. SI skills required include DOE analysis across channel variants, applying equalization and training as necessary for end-to-end channel analysis.
- Excellent documentation and communication skills, the ability to work independently, a desire to mentor, and demonstrated innovation are essential.
- The ability to multitask and drive multiple issues to closure is also necessary.
