Research Scientist Intern, Audio Systems (PhD)

Summary:

Meta's Hardware Audio Team is hiring a PhD Research Scientist Intern to help push the audio performance of next-generation wearables, where small speakers have to deliver full, rich sound. This internship focuses on finding ways to unlock the full capability of every speaker to deliver the highest possible audio quality. It spans our audio hardware and audio experience teams, and the work runs from measurement and analysis through prototyping and validating new methods on real devices. The project is intentionally open-ended: working with the engineers and researchers, you will help identify the most impactful directions. The ideal candidate has a strong research background in electroacoustics, loudspeaker modeling, acoustic measurement and digital signal processing (DSP). Our internships are twelve (12) to twenty-four (24) weeks long, and we have various start dates throughout the year.

Required Skills:

Research Scientist Intern, Audio Systems (PhD) Responsibilities:

1. Identify, develop and validate methods to drive every speaker up to its full capability

2. Research how speaker performance varies across units and operating conditions

3. Quantify improvement opportunities and connect them to end-to-end audio quality metrics

4. Design and run experiments in our audio labs, and analyze the resulting measurement data

5. Collaborate with cross-functional teams across audio hardware, tuning and algorithms

6. Communicate results through documentation, presentations and, where appropriate, publications

Minimum Qualifications:

Minimum Qualifications:
