Production Test Engineer – High-Speed Mixed-Signal ICs

Job Description

We are seeking a skilled **Production Test Engineer** to join our team, specializing in high-speed mixed-signal ICs. In this role, you will be responsible for the execution, optimization, and continuous improvement of test processes for high-performance mixed-signal ICs in a high-volume manufacturing environment. You will ensure the devices meet stringent quality standards while working with cross-functional teams to optimize test methodologies, troubleshoot test failures, and improve yield.

The ideal candidate will have experience with Automated Test Equipment (ATE), high-speed digital interfaces (e.g., SerDes), Analog circuit testing (e.g., ADCs, DACs, PLL), and mixed-signal ICs.

**Key Responsibilities**

1. **Test Execution \& Monitoring**

* Execute test plans for high-speed mixed-signal ICs, ensuring all performance criteria are met before production release.
* Perform automated testing on ATE platforms (e.g., Teradyne), focusing on both Analog and digital signal integrity, functionality, and power measurements.
* Monitor the production line for test performance, ensuring that all ICs meet quality standards before being shipped to customers.

1. **Troubleshooting \& Debugging**

* Troubleshoot and identify root causes of test failures in high-speed mixed-signal ICs, collaborating with design and quality teams to resolve issues.
* Perform failure analysis on devices that fail initial tests and implement corrective actions to prevent recurrence in future production runs.
* Work closely with design engineers to refine and debug test programs for both digital and Analog components.

1. **Test Optimization \& Process Improvement**

* Continuously improve test flow, reduce test time, and optimize throughput without compromising quality or test coverage.
* Participate in yield enhancement activities, analysing test data to identify patterns and implementing solutions to improve yield and reduce defects.
* Automate repetitive test tasks and implement new testing procedures to ensure efficiency and accuracy.

1. **Collaboration \& Reporting**

* Collaborate with design engineers to ensure that the test process is optimized for the manufacturability of mixed-signal ICs.
* Provide detailed test reports, including yield data, test results, and analysis of device performance. Share insights and recommendations with senior management to enhance production efficiency.

1. **Test Equipment Management**

* Maintain and calibrate test equipment to ensure accuracy and reliability, including Automated Test Equipment (ATE), oscilloscopes, logic analyzers, and signal generators.
* Ensure that test hardware is properly set up, configured, and validated for each new device under test (DUT).
* Troubleshoot and resolve any issues related to test equipment functionality.

**Qualifications**

* **Education:** Bachelor's degree in electrical engineering, or a related field.
* **Experience:** 4 years of experience in **production testing** of **high-speed mixed-signal ICs** or similar semiconductor devices.
* **Skills:**
* Hands-on experience with Automated Test Equipment (ATE) such as Teradyne, Advantest, or National Instruments.
* Experience testing high-speed digital interfaces (e.g., SerDes) and Analog mixed-signal components (e.g., ADCs, DACs, amplifiers, PLL).
* Familiarity with testing methodologies for signal integrity, timing analysis, and power consumption in high-speed devices.
* Proficiency in using oscilloscopes, logic analyzers, and signal generators.
* Experience with test data analysis and reporting tools.
* Strong problem-solving and analytical skills to diagnose and resolve test failures.
* Good communication skills to collaborate across engineering and production teams.
* Ability to work efficiently in a fast-paced production environment with a focus on continuous improvement.
