Hardware Test Engineer - Optics & Calibration

The Optics characterization and Calibration Test Engineer applies the highest level of skill and knowledge of Opti-mechanical principles in designing optics test architecture and developing calibration algorithms. You will drive the conceptual test design with engineering in early product exploration stage and validate with first article design in the lab for proof of engineering. You will lead the deployment of hardware test systems with manufacturing partners and third-party integrators during NPI build once concept design is well proven. You will be leading in troubleshooting station hardware/software issues on test equipment and systems. You will also lead overall product test strategy, evaluate test equipment and qualification processes based on production metrics, and lead and facilitate integration of test systems into our existing data tracking networks and factory control systems (MES/ShopFlow). You will be designing and documenting new manufacturing equipment with standardization and reliability as a priority and creating test plans for validating existing equipment. 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 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.
