Product Test Engineer

Job Title

Product Test Engineer

Role Summary

Responsible for developing and executing silicon test content and validation for programmable logic devices. Works with cross-functional teams (design, applications, manufacturing) to verify IP functionality pre- and post-silicon and drive resolution of product issues.

This role focuses on ATE and bench validation, test circuit development using FPGA fabric, automation of test generation, and coverage analysis to ensure product readiness.

Experience Level

Senior-level. The posting specifies senior experience (e.g., BS + 8 years industry experience or MS + 6 years); expect experienced test/validation engineers.

Responsibilities

Primary responsibilities include planning, developing, and executing test content and coordinating cross-functional resolution.

• Develop test plans targeted at chip IP functions and features.
• Design and implement test circuits using FPGA fabric and embedded IP.
• Develop scripts to automate test generation and perform Pre-Si verification.
• Execute Post-Si validation using wafer-level and package-level ATE and bench platforms across process, temperature, and voltage conditions.
• Identify root causes of product marginalities and coordinate closure with relevant teams.
• Own IP test content development and drive issues to resolution.
• Plan and deliver test content to meet schedules for internal and external sample deliveries.
• Extract coverage metrics using fault grading and recommend coverage improvements.

Requirements

Must-have technical skills and experience (concise). Education-specific requirements are listed under Education Requirements below.

• Must-have: Practical experience with semiconductor devices and test methodologies; ATE test program development, integration, and debug; IC characterization and failure analysis using bench instruments.
• Experience with wafer sort, package assembly, and final test (backend IC process).
• Experience developing test content and automating test generation and verification.
• Proficiency with scripting/programming (e.g., Python, C++).
• Strong analytical, problem-solving, and verbal/written communication skills; ability to work across teams and cultures.
• Familiarity with Windows and Unix environments and standard office tools.
• Nice-to-have / advantageous: Hands-on experience with Nextest Magnum, Advantest T2K, or Teradyne UltraFLEX; programmable logic experience; RTL design and design verification background; DFT methodologies (scan, BIST), memory test, and fault grading; HDL knowledge (Verilog/VHDL).

Education Requirements

BS in Electrical, Electronics, or Computer Engineering with ~8 years industry experience, or MS in those fields with ~6 years industry experience. Equivalent practical industry experience may be acceptable as implied by experience-based requirements.
