Senior Software Engineer - Video Platform

Build and maintain our iOS integrations using Swift, ensuring video and rendering capabilities work seamlessly on mobile. You'll also integrate TypeScript APIs into our Angular web application to surface platform capabilities to users.

Profile and optimize video and rendering workloads, reduce processing latency, minimize memory footprint, and improve throughput across our pipeline. Build observability into our systems to understand real-world performance and debug issues across the full stack.

Collaborate closely with editor engineers to integrate video and rendering capabilities into the user-facing product. We value clear communication, thoughtful problem-solving, and code that will be maintainable in two years.

We're looking for engineers with depth in at least two of these areas:

C++ and rendering: Experience with graphics engines, Skia, or GPU programming (WebGPU, Metal, WebGL)

C++ and video processing: Deep FFmpeg knowledge, codec expertise, real-time video pipelines

TypeScript and web platform: WebCodecs, WebAssembly integration, Angular or similar frameworks

Swift and iOS: Native iOS development, platform integration, media frameworks

The ideal candidate combines C++ systems experience with either web platform knowledge (our current highest priority) or iOS integration skills. Exceptional candidates with pure C++ depth across both video processing and rendering will also thrive here.

5+ years of professional programming experience

Strong proficiency in C or C++, with additional depth in TypeScript or Swift

Experience with video processing (FFmpeg, GStreamer, libav) or graphics rendering (Skia, OpenGL, Metal)

Working knowledge of video codecs (H.264, H.265, VP9, AV1) and container formats

Understanding of cross-platform development targeting web and native runtimes

Built for WebAssembly using Emscripten or similar toolchains

Worked on real-time video processing, streaming, or graphics rendering

Optimized for memory-constrained or GPU-accelerated environments

Integrated native code with web or mobile platforms

Built or maintained observability for complex systems

You use, or want to use, AI tools to move faster - and take responsibility for the output

Comfortable with asynchronous communication and clear documentation

Able to context-switch across problem spaces (video, rendering, iOS, web)

Video Processing: C/C++, FFmpeg, WebAssembly, Emscripten, WebCodecs

Rendering: Skia, WebGPU, Metal, WebGL, arm64

Web: TypeScript, Angular, Node.js

iOS: Swift

Infrastructure: Observability tooling, performance monitoring
