Optical Test Engineer - Sensing Modules

Shanghai, China

Do you enjoy solving complex engineering challenges by writing software that interfaces directly with hardware systems? Are you passionate about test automation, data integrity, and smart control solutions at scale? At Apple, quality is built into everything we do. Our test engineers are essential to that mission, designing advanced test solutions that uphold the industry's highest standards. The Sensing Technology team develops breakthrough features like Face ID, Touch ID, and True Tone Display. We are looking for a software engineer with a deep understanding of instrumentation and algorithms, who can design robust software solutions to drive and optimize sensor test systems in mass production. This role is ideal for optical engineers who excel in precision metrology and are eager to broaden their expertise across advanced software frameworks, opto-mechanical systems, and high-speed instrumentation. It offers a clear path from specialist Optical Engineer to system-level Optical Test Solution Architect. You will lead seamless integration across Apple's optical design teams and global vendor ecosystems by building robust test architectures that enable scalable collaboration and consistent execution across worldwide manufacturing sites.

Description

In this role, you will:

• Design and develop advanced optical sensor test stations and integrate sophisticated instrumentation
• Build algorithms for calibration, validation, and optimization in high-volume manufacturing environments
• Apply advanced data processing or AI/ML techniques to improve test coverage, accuracy, and yield
• Collaborate with cross-functional teams to deliver integrated mechanical, electrical, and software test solutions
• Debug complex optical-electrical-software issues and lead system commissioning at global manufacturing sites

Minimum Qualifications

MS/PhD in Optical Engineering, Applied Optics, Physics with focus on precision metrology

3+ years of experience in optical test engineering, precision metrology, or photonic instrumentation

Proficiency in Python and C/C++ for optical hardware control and test automation

Strong knowledge of optical instrumentation (e.g., spectrometers, interferometers, power meters, beam profilers, detectors)

Experience implementing algorithms for calibration, spectral/photometric analysis, or optical signal processing

Proven ability to collaborate with cross-functional teams to deliver precision optical systems

Preferred Qualifications

Experience in optoelectronic device characterization or optical sensor validation (e.g., LEDs, VCSELs)

Familiarity with AI/ML techniques for data analysis or yield optimization

Background in optical system design and modeling (Zemax/CodeV or equivalent)

Knowledge of optical calibration standards (NIST traceability, CIE colorimetry, radiometry)

Exposure to instrumentation, control systems, signal processing, or machine learning is highly preferred
