You have experience developing robust software and algorithms in a modern object-oriented or scripting language (e.g., Python, C++). Familiarity with the Apple ecosystem is a plus but not required.

Background in testing high-volume consumer electronics, particularly with Touch, Sensing, Display, or other complex user-facing technologies.

Knowledge of digital signal processing (DSP) or image processing algorithms.

Experience with instrument camera and optical capture system is a plus.

Communication: Excellent written and verbal communication skills, with an ability to collaborate with cross-functional engineering and design teams.

Passion for learning and contributing across disciplines.

Analytical Problem-Solving: Excellent skills in debugging and performing failure analysis across software, hardware and system domains. Experience with structured problem-solving methodologies like Design of Experiments (DOE). Ability to perform and interpret statistical data analysis

The Instrumentation and Test technology team architects and designs best-in-class, end-to-end test and measurements systems.
We are a collaborative group of creative and thoughtful people developing highly complex and sophisticated systems to validate the performance of sensors and other critical technologies in our world-class products.
This individual will play a key role in designing comprehensive test strategies, methodologies, and integrating the measurement systems to support new product introduction, characterization, ramp, and mass production. This includes everything from defining high level test plans to architecting the specific instruments required to execute them.
