The Test Automation Engineer – Optics applies the highest level of skill and knowledge of laser optics, imaging, metrology and computer algorithms in designing test/calibration stations for consumer electronics devices on a subassembly and system level. You will drive conceptual test system hardware design with technology groups in the early product exploration stage and validate first article design in the lab. You will lead the end-to-end development of software and hardware integration, including test flow, instrument control, robotics/motion control, data capture and process, and integration of advance algorithms with third-party partners. You will be leading in documenting and troubleshooting station hardware/software issues on test equipment and systems and bridge to production. The ideal candidate is a self-driven individual working in a cross-functional team environment and will be responsible for planning the design, development, and implementation of factory test/calibration systems. You will enforce manufacturability, testability and ensure cost-effective designs are implemented for testing and automation systems, software, and equipment. This position will have responsibilities for NTI and NPI test development and bridge to sustaining support of production. You must be responsive, flexible, and able to succeed within an open collaborative peer environment. We are looking for someone with a productive mindset who can apply their expertise to solve problems in creative, insightful ways.
