Test Engineer

Job Title

Test Engineer

Role Summary

Own wafer-level, packaged, and system-level testing for batteryless SoCs. Work with design, DFT, product, and manufacturing teams to develop, validate, and transfer test solutions that ensure functionality, performance, and manufacturability.

Experience Level

Mid-level. 2+ years of semiconductor test experience preferred.

Responsibilities

Execute and maintain test infrastructure across wafer, package, and system stages.

• Develop and execute test plans for wafer-level, packaged, and system-level testing.
• Build and maintain automated test programs and ATE setups (Teradyne/Advantest or custom rigs).
• Generate test patterns; validate functionality, performance, and parametrics.
• Debug test failures and correlate lab results with silicon and production data.
• Support silicon bring-up and transition from lab to production.
• Analyze test data for yield, margin, and process variation; recommend improvements.
• Design and develop test hardware: load boards, probe cards, sockets.
• Document procedures and support test transfer and production ramp activities.

Requirements

Skills and experience required or highly recommended for the role.

• Semiconductor test experience (bench or ATE); 2+ years preferred.
• Experience with ATE platforms or custom automated test setups (Teradyne/Advantest preferred).
• Test scripting/programming: Python, C/C++, LabVIEW, or ATE languages.
• Strong understanding of analog and digital measurements and lab instrumentation.
• Familiarity with IC test methodologies: parametric, functional, boundary testing.
• Ability to analyze large datasets and extract yield/margin insights.
• Strong debugging skills and attention to detail; comfortable working in lab environments.
• Nice-to-have: knowledge of DFT (scan, BIST, JTAG); experience with yield improvement and test-time/cost optimization.

Education Requirements

Degree in Electrical or Computer Engineering or a related field.
