Test & Instrumentation Development Engineer

Summary

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.

Minimum Qualifications

Our ideal candidate has experience in test integration, implementation, and has a strong foundation in at least one of the following core areas: system or application-level test software or instrumentation hardware design. Minimum of bachelor's degree in Electrical Engineering (EE), Electrical & Computer Engineering (ECE) with 3+ years of relevant industry experience in a hands-on technical role. 3+ years of experience in a programming language like C/C++ or Python

Preferred Qualifications

End-to-end Test Design: Experience creating and documenting comprehensive test plans, defining test cases and coverage, and developing validation methodologies for complex systems. International Travel: This role requires international travel (up to 25%) to support our manufacturing partners during key product builds. This typically involves 2-4 trips per year at sites in Asia. Our team is committed to providing as much advance notice as possible to support your planning. Curiosity and Adaptability: You are driven by curiosity, energized by solving novel problems, and motivated to learn new skills to get the job done. Focused Problem Solving: You excel at identifying the most critical variables in a complex system and can develop a clear, focused plan of action even when all the details are not yet available. Hands-on experience with electronics debugging tools. Electrical engineering fundamentals (ability to read schematics & layout & component datasheets). 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. Master's degree preferred.

Description

You will play a key role in architecting, designing, and deploying the complete test solutions—including hardware, software, and algorithms—for our next-generation products. Partnering closely with a wide range of cross-functional teams, you will develop the critical test methodologies and instrumentation needed for system characterization, calibration, and validation in a fast-paced and collaborative product development environment.
