• Take ownership of and enhance segments of our AVFoundation camera infrastructure: capture sessions, devices, formats, frame rates, exposure, and device capabilities.

• Construct and refine real-time image and video processing frameworks.

• Enhance capture quality, latency, stability, and fluidity across all supported iPhone models.

• Work on multi-camera workflows, front and back video composition, video encoding, media export, and audio/video synchronization.

• Optimize CPU, GPU, memory, battery usage, thermal performance, buffer allocation, and multithreaded processing.

• Analyze device-specific and iOS-version-specific behaviors, proposing practical technical trade-offs.

• Collaborate closely with iOS engineers, product managers, designers, backend developers, and data teams.

• Directly contribute to the codebase and elevate engineering standards regarding media performance and reliability.

⛳️ Requirements
