Instrumentation & Test SW Dev Engineer

Cupertino, California, United States Hardware

The Instrumentation and Test technology team architects and designs best‑in‑class, end‑to‑end test and measurement 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 implement them. We are looking for a systems‑thinking engineer ready to take ownership of complex test solutions. 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.

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.

• Architect, design, develop instrumentation hardware, software & firmware platforms required to test and calibrate sensors
• Create production instrumentation software and roll‑out suppliers
• Author sensing technology instrumentation engineering requirements documents
• Prototype, bring‑up, debug and characterize instruments for new Apple products
• Prepare and deliver technical presentations, conduct defect root‑cause analysis and resolution, including diligent bug database tracking
• Act as the supplier liaison, supporting instrumentation bring‑up and qualification of engineering builds, usually in Asia

• BS and a minimum of 3 years relevant industry experience
• 3+ years of experience in programming languages such as C/C++ or Python

• 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: positions require up to 25% travel to support manufacturing partners during key product builds (2–4 trips per year to sites in Asia)
• Hands‑on experience with electronics debugging tools
• Electrical engineering fundamentals (ability to read schematics, layout & component data‑sheets)
• Background in testing high‑volume consumer electronics, particularly with Touch, Sensing, Display, or other complex user‑facing technologies
• Ability to perform and interpret statistical data analysis
• Experience with structured problem‑solving methodologies such as Design of Experiments (DOE)
