Semiconductor Product Engineer

Job Title

Semiconductor Product Engineer

Role Summary

Lead development and deployment of manufacturing test solutions for AI accelerator silicon from first‑silicon bring‑up through high‑volume production. Work cross‑functionally with design, DFT, packaging, OSATs and manufacturing to define test strategy, develop ATE content, debug silicon issues, and optimize yield, coverage, and test cost.

Experience Level

Mid-level (guidance: 5+ years semiconductor test engineering experience).

Responsibilities

Main responsibilities include:

• Define test strategy and methods for AI accelerator chips targeting high-volume manufacturing.
• Develop and manage ATE test content for advanced CMOS designs including high-speed logic, SRAM/DRAM and IO blocks.
• Implement and debug structural and functional tests (scan/ATPG, LBIST, MBIST, JTAG, HSIO).
• Bring up first silicon on ATE: pattern debug, tester correlation, shmooing, and corner analysis.
• Validate and margin high-speed interfaces (e.g., PCIe Gen5/Gen6, multi‑GHz LPDDR) with at-speed tests.
• Perform silicon characterization and failure analysis to identify yield limiters and defect mechanisms.
• Optimize test coverage, test time, and cost while maintaining manufacturing robustness.
• Collaborate with DFT, design, packaging teams and OSATs for testability improvements and program deployment.
• Support qualification, reliability testing, high-volume manufacturing ramp and documentation of test programs.

Requirements

Must-have qualifications:

• 5+ years of hands-on semiconductor test engineering experience.
• Experience developing ATE test programs (Advantest 93K, Teradyne, or similar).
• Strong understanding of DFT methodologies (scan, ATPG, MBIST, LBIST) and memory test techniques.
• Proven ability to debug silicon issues and correlate failures to design or process causes.
• Familiarity with advanced CMOS nodes and production test challenges.
• Ability to work effectively in cross-functional engineering environments.

Nice-to-have:

• Experience testing AI accelerators, GPUs, networking ASICs, or other high-performance compute ICs.
• Experience with PCIe Gen5/Gen6, LPDDR4/5/6 or other high-speed interfaces.
• Exposure to advanced packaging, chiplets, die-to-die test flows and yield/test optimization in HVM.

Education Requirements

Not specified.
