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. You will play a critical role in the entire product lifecycle, from initial design reviews to mass production, ensuring that every product leaving our manufacturing lines meets our rigorous quality and performance specifications.

This role requires a blend of deep technical expertise, strategic thinking, and the ability to work effectively with large-scale contract manufacturers (CMs) and product development engineering across the globe.

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. Proactively drive continuous improvement to optimize test coverage, cycle time, and overall manufacturing efficiency.
• Collaboration with Contract Manufacturers (CMs): Act as the primary technical interface with our large-scale contract manufacturing partners. Train and support CM teams on test processes, troubleshoot issues on the factory floor, and ensure strict adherence to our specifications.
