Core Audio Software Engineer

About the role

In this role, you will architect and evolve the end-to-end spatial audio pipeline - from codec integration, mix engine, to audio output for headphones, built-in speakers, and external multi-channel systems. You will design system-level APIs that enable apps and other Apple frameworks to integrate our spatial and multichannel audio capabilities.

Responsibilities

• You will drive the technical relationship with external codec vendors, aligning on SDK integration strategy, format evolution, and new features.
• You will collaborate closely with Bluetooth audio, AirPlay, Core Media, and other framework teams to deliver immersive audio experiences that work seamlessly across Apple's ecosystem.

Requirements

• Experience integrating third-party codec SDKs into platform audio frameworks.
• Experience developing or maintaining audio file format parsers or media container demuxers.
• Familiarity with loudness standards and dynamic range control.
• Experience with Apple audio frameworks (Audio Toolbox, Audio Unit, Core Audio) or comparable platform audio stacks.
• Strong C++ systems programming skills (C++17 or later) with experience writing performance-critical, real-time code.
• Strong understanding of multichannel audio formats and audio codec pipelines (AAC, Dolby codecs, or similar).
• Deep experience with real-time audio systems: low-latency signal processing, mixer graphs, and hardware I/O.
• Experience designing and shipping system-level APIs.
• BS or MS in Computer Science, Electrical Engineering, or equivalent experience.
• 8+ years of professional software development experience in audio or media playback.
• Pay & Benefits
• Note: Apple benefit, compensation and employee stock programs are subject to eligibility requirements and other terms of the applicable plan or program.
