Characterize microLED devices for ultra-low power high bandwidth interconnects using automated test setups and advanced metrology.
About the role
Avicena is seeking a Micro LED Characterization Engineer based in Sunnyvale, CA to perform optical, electrical, and thermal characterization of microLED devices across the development lifecycle. The role supports microLED-based ultra-low power high bandwidth interconnects designed for chip-to-chip communications.
What you'll do
- Perform optical, electrical, and thermal characterization of microLED devices throughout the development lifecycle.
- Design, develop, and maintain automated measurement systems and test scripts to improve characterization efficiency and repeatability.
- Analyze characterization data to extract key performance metrics, including optical output power, forward voltage, emission wavelength, external quantum efficiency (EQE), and device reliability/degradation characteristics.
- Drive root cause analysis of device performance and reliability issues, delivering recommendations to process, device, and design engineering teams.
- Maintain, calibrate, and troubleshoot laboratory equipment to ensure measurement accuracy and reliability.
- Mentor junior engineers and technicians in characterization techniques, data analysis, and laboratory best practices.
What you'll need
- Bachelor's or Master's degree in Electrical Engineering, Physics, Materials Science, Optics, or a related technical field.
- 10+ years of industry experience in semiconductor or optoelectronic device characterization.
- Strong understanding of electrical, optical, and thermal characterization techniques for semiconductor devices.
- Experience with automated test systems and measurement instrumentation.
- Proficiency in JMP, Python, Excel, or similar data analysis tools.
- Experience with statistical data analysis and Design of Experiments (DOE).
Nice to have
- Ph.D. or M.S. in Electrical Engineering, Materials Science, Physics, Optics, or a related field.
- Direct experience with microLED, LED, VCSEL, laser, or other III-V semiconductor device characterization.
- Familiarity with metrology tools such as Scanning Electron Microscopy (SEM), optical microscopy, profilometry, and other optical characterization techniques.
- Experience with reliability testing, failure analysis, and lifetime characterization.
- Experience developing automated test software using Python, LabVIEW, or similar programming environments.
- Knowledge of semiconductor fabrication processes and process integration.

How we counted: 653 open Silicon Test Engineering (DFT Test) roles from 86 employers tracked in the SemiconductorJobs index, counted 11 Nov 2026. Specialty figures count only roles carrying this exact specialty label, so an employer's related work in neighbouring specialties is not included there, and is counted in the wider Silicon Validation & Test family row. Days are counted from when our index first saw each posting, not from the employer's original posting date.
