Design and implement performant systems for real-time video editing, animation, and rendering
Collaborate with product and design to bring a fluid, intelligent, canvas-like creative experience to life

Experience working with Rust and Python stacks
Experience building creative or design tools (e.g., video editors, animation UIs, timelines)
Strong systems thinking, capable of owning complex technical decisions across the stack
AI-Forward Thinking
Familiarity with current and emerging AI/ML trends in video and media
Foundation models, generative video/image (e.g., Stability, Runway, OpenAI, etc.)
Transcription and speech-to-text (e.g., Whisper, Deepgram)
Vector embeddings, retrieval-augmented generation, or on-device inference
Curiosity and imagination around how AI can amplify creativity, not just automate tasks
Nice to Have
Experience with FFmpeg, media pipelines, GPU compute, or cloud rendering infrastructure
Knowledge of WebRTC, WebSockets, or real-time collaboration tooling
Open-source contributions in creative tech, media processing, or AI frameworks
Why Join Us? ~
Lead the platform — you’ll have a pivotal role in defining how the entire product works
Work on bleeding-edge tech at the intersection of creativity, video, and AI
Join a small, high-caliber team with a product-first mindset and design obsession
High impact, strong ownership, and equity upside in a fast-growing space
Help shape a product that could empower millions to tell better stories
