Senior iOS Computer Vision Engineer (AVFoundation + C++ OpenCV Optimization)

Summary

PROJECT OVERVIEW ==================================== We are building a local-first, native iOS utility application optimized for high-performance physical document and structural surface data ingestion. We are seeking an Expert Mobile Computer Vision Engineer to develop a standalone camera ingestion module responsible for real-time frame capturing, spatial matrix calculations, and coordinate output. Your sole responsibility is ensuring that a live video feed from an iPhone mounted on a desktop tripod can dynamically isolate a structured physical workspace grid, mathematically correct non-orthogonal perspective warps, and cleanly pass flat data arrays to our core application engine. You will NOT be building consumer UI, layout menus, or cloud database integrations. This is a low-level graphics, mathematics, and memory management milestone. CORE RESPONSIBILITIES & DELIVERABLES ==================================== 1. LOW-LATENCY INGESTION: Configure a robust, hardware-level frame buffer pipeline utilizing Apple’s AVFoundation framework to pull raw CMSampleBufferRef streams natively at a stable frame rate without triggering device thermal throttling. 2. GEOMETRIC NORMALIZATION: Implement real-time Homography algorithms and Perspective Warps using C++ OpenCV to instantly flatten a physical, square workspace grid captured from varying, skewed tripod angles. 3. TRANSIENT NOISE FILTERING: Establish logic frameworks to detect and filter out temporary occlusion (e.g., a hand passing over the workspace or placing an object on the surface), ensuring the underlying data ledger only registers permanent state updates. 4. SWIFT INTEROP BRIDGING: Construct highly optimized Objective-C++ wrappers or modern Swift/C++ Interop layers to pass the calculated tracking arrays seamlessly across to our master Swift core application state. TECHNICAL REQUIREMENTS ================================================================================ - Mastery of native iOS development (Swift & Objective-C++ Interop). - Strong production history with C++ (14 or higher) and OpenCV mobile compilation. - Deep expertise in Apple's AVFoundation, CoreVideo, and local pixel buffer manipulation. - Experience with Metal or CoreImage for custom GPU/hardware acceleration is a significant plus. - A strong foundation in linear algebra, matrix operations, and spatial tracking geometry. HOW TO APPLY ================================================================================ Please submit a brief summary detailing your specific experience with real-time video buffer manipulation or native mobile computer vision applications (e.g., advanced document scanners, spatial tracking tools, or AR components). Please explicitly mention your experience bridging native C++ codebases over to Apple’s Swift runtime environment.
