Job Description

Dolby is looking for passionate new graduates and junior engineers to join our Android audio integration test team.

In this role, you will work at the intersection of cutting-edge audio technology and mobile software engineering — helping to ensure that Dolby's world-class audio algorithms perform flawlessly on Android devices.

You'll design and build test systems that scale, and you'll have the opportunity to shape how AI-powered tools transform the way we test.

Responsibilities

1. Test Audio Algorithm Integration

  • Validate the integration of Dolby audio algorithms into Android mobile platforms, ensuring correctness, performance, and reliability across diverse devices.
  • Analyze requirements, system behavior, and potential risk areas to design comprehensive test cases with clear functional coverage and boundary conditions.
  • Implement and maintain automated test scripts and frameworks to accelerate test execution.
  • Maintain clear test documentation, report defects with precision, and communicate test results to stakeholders.

2. Adopt AI-Powered Testing Tools

  • Evaluate and integrate emerging AI tools and methodologies to improve test efficiency, anomaly detection, and coverage analysis.

3. Collaborate Cross-Functionally

  • Work closely with integration developers, PMs, audio algorithm engineers, support engineers and QA leads to discuss schedules, identify gaps, reproduce issues, and drive quality improvements.

Qualifications

  • Bachelor’s degree or higher in Computer Science, Electrical Engineering, Audio Engineering, or a related field — new graduates welcome.
  • Foundational knowledge of the Android audio stack and multimedia frameworks.
  • Hands-on experience writing Python scripts for automation, data processing, or testing.
  • Curiosity and a growth mindset — eager to learn new tools, frameworks, and domains quickly.
  • Excellent English communication skills (written and verbal) for seamless collaboration with global R&D teams.

Preferred Qualifications

  • Experience with Android development tools (ADB, Android Studio, Logcat, etc.).
  • Basic understanding of Digital Signal Processing (DSP) concepts, such as filtering, frequency domain analysis.
  • Exposure to AI/ML frameworks (e.g., TensorFlow, PyTorch) or AI-assisted testing tools.
  • Experience with test frameworks such as pytest, unittest, or Android Instrumentation.
  • Familiarity with CI/CD pipelines and version control (Git).

What We Look For (The Plus Factor)

  • Academic or personal projects involving audio processing, signal analysis, or mobile development.
  • Contributions to open-source testing or audio-related projects.
  • Experience with audio quality evaluation tools or perceptual audio metrics.

About Dolby Laboratories

We're the rain on the roof in a movie. The music flowing through your earbuds when you're at the gym. The footsteps lurking behind you in a video game. The voice of a colleague on a call who seems to be right next to you. The sight of a breathtakingly bright and vivid sunset on your TV.

Making experiences come alive through technology is what we do. It's been our mission since day one.

It began with our founder, Ray Dolby, a visionary scientist and inventor. As a young engineer and music lover, he was driven to improve the listening experience. And with that simple motivation, plus countless hours of experimentation, he created a solution—a solution that was elegant and practical, highly sophisticated, and wholly devoted to the artist's vision. Even as we've become a global company, Dolby Laboratories continues to reflect Ray Dolby's values. Here, science meets art. And high tech goes far beyond computer code.

Founded in 1965 and headquartered in San Francisco, Dolby has grown into a leading global innovator and developer of audio, imaging and voice technologies for cinema, home theaters, PCs, mobile phones, and games. Our products include Dolby Digital Plus, TrueHD, Dolby Voice, Dolby Atmos and Dolby Vision. Today, over 2,000 individuals around the globe share their talents and energy to enable the most immersive experiences that technology can deliver.
