This is a fully remote opportunity with a US-based company, operating during South African working hours. The successful candidate will be responsible for developing and maintaining desktop and Apple-platform applications within a C++/Qt environment. The role focuses on real-time video capture, streaming, and playback technologies, with a strong emphasis on the macOS user experience, as the majority of users operate on Apple devices. Responsibilities span the full application lifecycle, from low-level media processing and optimisation through to building, code signing, notarising, and delivering high-quality native applications.

DUTIES:

• Developing and maintaining desktop and Apple-platform applications using C++ and Qt.
• Designing, building, and enhancing features for a real-time collaboration platform used by post-production teams.
• Developing and supporting real-time video capture, streaming, and playback functionality.
• Optimising application performance to ensure frame-accurate 4K video livestreaming.
• Focusing on delivering a high-quality macOS user experience across the platform.
• Working with low-level media processing, video handling, and streaming technologies.
• Troubleshooting and resolving application, performance, and media-related issues.
• Collaborating with cross-functional teams to deliver new features and product enhancements.
• Building, packaging, and deploying native desktop applications.
• Managing application code signing, notarisation, and release processes for Apple platforms.
• Ensuring software reliability, stability, and scalability across supported environments.
• Participating in code reviews and maintaining high software development standards.
• Testing, debugging, and maintaining applications throughout the software development lifecycle.
• Contributing to the continuous improvement of architecture, performance, and user experience.
• Supporting the delivery of production-ready software used by leading global studios, agencies, and brands.

REQUIREMENTS:

• 10 Years Deep C++ expertise (the kind that comes from years of shipping production software) and strong command of the Qt framework
• Hands-on experience with WebRTC and GStreamer
• Working knowledge of video codecs, particularly 264 and H.265 (HEVC)
• Proven experience building and packaging macOS applications including code signing, notarisation and update tooling such as Sparkle

Nice to have:

• Mac-first instincts and fluency in Xcode
• Broader audio/video codec and real-time media processing experience
• Swift, with iOS / tvOS development history
• Basic JavaScript / React (or the appetite to learn it)
• Familiarity with Windows desktop development (the product supports Windows too)

ATTRIBUTES:

• A self-starter mindset: comfortable taking ownership, working independently in a small fast-moving team, and picking up whatever you don’t already know
