Job Title: User Experience Designer II
Location: Sunnyvale, CA
Duration: 6 Months (Possibility of Extension)
 
Job Description:
We’re seeking an Optical Design Technologist and Metrology Engineer to build AR optical prototypes from the ground up, developing software in Unity/Unreal, designing image viewer apps for 3P benchmarks, assembling hardware, conducting rigorous metrology, and managing the data infrastructure. You'll prototype displays, characterize performance through optical measurements, and validate designs through user studies, combining hands-on development with data-driven research


AR Software Development

• Develop AR applications using Unity or Unreal Engine for prototype testing and user studies
• Create custom image viewer applications for 3rd party AR devices for benchmarking and competitive analysis
• Proficiency in MATLAB, C#, C++, or Python for application development and scripting
• Troubleshoot hardware/software integration issues in prototype systems
• Build custom tools for automated testing, data collection, and system calibration

 
Prototyping & Fabrication

• Assemble AR optical prototypes using off-the-shelf and custom components (optics, displays, sensors)
• Design and fabricate custom fixtures using CAD software (SolidWorks, Fusion 360, OnShape)
• Experience with rapid prototyping techniques including 3D printing (FDM, SLA) and basic fabrication methods

Optical Metrology

• Conduct optical measurements to characterize display performance: luminance, color accuracy, MTF, distortion, field of view
• Maintain and calibrate laboratory instruments (photometers, colorimeters, spectrometers, optical benches)
• Document system specifications and measurement methodologies with attention to repeatability and accuracy

 
Data Management & Analysis

• Design and implement database schemas for storing experimental data, user study results, and metrology measurements (SQL, NoSQL)
• Build data pipelines to automate collection, validation, and storage of large datasets
• Develop analysis scripts in Python, MATLAB, or R to process optical measurements and user study data
• Create visualizations and dashboards to communicate findings to cross-functional teams

 
Communication and Collaboration

• Strong written and verbal communication skills to document and present findings to internal stakeholders
• Excellent organizational skills and attention to detail in record-keeping and documentation

 
Education & Experience

• Master's and/or PhD degree in Computer Science, Electrical Engineering, Optical Engineering, Human-Computer Interaction, or related field
• 2+ years of hands-on experience building AR/VR systems or prototypes

 
Preferred Qualifications
User Studies & Research

• Create experimental stimuli and interactive environments for perceptual studies
• Interest in running user studies and working with human participants
• Experience designing and conducting user studies to evaluate AR display quality, comfort, and usability
• Correlate subjective feedback with objective optical measurements to validate design decisions
• Collaborate with vision scientists to design psychophysical experiments
• Familiarity with IRB processes and human subjects research protocols

 
Top Must Have:

• AR software development experience
• Prototyping & Fabrication Experience
• Optical Metrology Experience
