Test Engineer, Manufacturing

About the Role

As a Manufacturing Test Engineer, you will be the technical expert responsible for developing, implementing, and optimizing manufacturing test solutions for our next-generation wearable devices.

Responsibilities:

• Test Strategy & Development: Architect and implement comprehensive manufacturing test strategies for new product introductions (NPIs), covering functional, parametric, and in-circuit testing for complex wearable devices.

• Test Fixture & Equipment Design: Design, develop, and qualify test fixtures, equipment, and software for various stages of the manufacturing process, from PCBA-level tests to final product assembly.

• Specialized Testing: Develop and optimize test solutions for specialized functions critical to our products, including:

  • Audio Testing: Acoustic test methodologies for speakers, microphones, and other audio components.

  • Camera & Imaging Testing: Calibration and functional tests for high-resolution cameras and optical systems.

  • RF & Wireless: Testing for wireless connectivity, including Bluetooth, Wi-Fi, and other RF protocols.

  • Sensors: Calibration and functional testing for various sensors (accelerometers, gyroscopes, biometric sensors).

• Data Analysis & Optimization: Utilize data analysis tools to automatically monitor test yields, identify trends, root cause failures, and flag production issues.

• Collaboration with Contract Manufacturers (CMs): Act as the primary technical interface with our large-scale contract manufacturing partners.

• Design for Testability (DFT): Partner with the product design and engineering teams during the development phase to influence product architecture and design for enhanced testability, manufacturability, and reliability.

• Documentation: Create and maintain detailed test specifications, process instructions, and engineering change notices (ECNs) to ensure clear communication and consistency across all manufacturing sites.

• Project Leadership: Lead and mentor junior engineers, providing technical guidance and expertise on complex test challenges.

Required Qualifications:

• Deep expertise in developing test solutions for consumer electronics, including PCBA, FATP (Final Assembly, Test, and Pack), and system-level testing.

• Demonstrated experience with specialized testing:

  • Audio: Expertise with audio test equipment (e.g., Audio Precision, SoundCheck) and methodologies.

  • Camera: Experience with optical test benches, image quality analysis, and camera calibration.

  • RF: Experience with RF test equipment (e.g., spectrum analyzers, network analyzers) and wireless protocol testing.

  • Battery: Experience with battery testing methodologies, including charge/discharge cycling, impedance spectroscopy, and safety testing.

• Experience working directly and extensively with large-scale Contract Manufacturers (CMs), including overseas travel for factory support and new line bring-up.

• Strong knowledge of statistical process control (SPC), GR&R, and data analysis tools to drive yield improvements.

• Excellent problem-solving, communication, and interpersonal skills.

Preferred Qualifications:

• 10+ years of hands-on experience in manufacturing test engineering within the consumer electronics industry.

• Proven experience with wearables is highly preferred, including familiarity with the unique challenges of small form factor, high-density products.

• Proficiency in a programming language for test automation (e.g., Python, C#, LabVIEW).

• Demonstrated experience with specialized testing and calibration for eye tracking and vision.

• Bachelor's or Master's degree in Electrical Engineering, Mechanical Engineering, or a related field.
