About the Role
At Lumina Platforms, we’re reimagining the future of content creation — blending intuitive design, powerful editing tools, and AI-native capabilities into a single seamless, agentic, co-creative experience. Our platform will empower creators, marketers, and teams to produce professional-grade video content with unprecedented ease, speed, and intelligence.
We’re looking for a Principal Software Engineer to play a lead role in building the next-generation platform orchestrated through a DOM-like structure written in Rust. We’re looking for engineers who obsess over correctness, performance, and building expressive tools that scale beautifully. You’ll be at the heart of our technical architecture — shaping the core experience and symbiotic relationship between AI & Platform that will transform creativity in the coming years.
What You’ll Do
- Lead architecture and development of our interactive video creation platform
- 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
- Stay ahead of the curve in emerging AI and video tech, helping us build not just for now, but for what’s next
- Set high standards for code quality, performance, scalability, and team collaboration
- Prototype and integrate AI-powered features such as:
- Smart editing suggestions
- Auto-generated captions, voiceovers, or transitions
- Dynamic scene assembly or auto-layout tools
What You Bring
- Technical Expertise
- 7+ years of software engineering experience, ideally across both frontend and backend
- Deep experience with React, TypeScript and custom rendering (Canvas/WebGL/WebGPU)
- 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
- 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
