Senior Full-Stack Engineer, AI Editing

Role Description

Slate is building an AI-first video editor where the AI agent isn’t a bolt on, it’s deeply integrated into the editor and the user’s brand and media library. You tell it what you want; it builds a plan, previews it, and executes across the timeline. We've built the early AI pipeline. Now we need a full-stack engineer to own the entire product experience on top of it: the chat-driven interface, timeline integration, streaming UI for AI plan previews, and the upload flows that feed into AI analysis. This is a high-ownership role on a small, fast-moving team. You'll ship real features end-to-end, from UI to backend services, in one of the most competitive spaces in video software right now.

What You'll Actually Do

• Build the AI editing interface
• Build the chat-driven editing interface, including:
  • Agentic loops
  • Streaming response rendering
  • AI plan previews
  • Suggested action surfaces
• Integrate the AI pipeline's outputs into the editor:
  • Rendering model plans
  • Handling async results
  • Keeping the UI responsive across long-running operations
• Own the properties panels, chat panels, and lightweight timeline components that make the AI-first experience feel native.
• Ship video processing UX:
  • Build upload flows and media analysis state communication
  • Design status indicators and progress surfaces for background processing, model inference, and asset analysis
  • Work closely with our AI Engineers to understand pipeline outputs and translate them into clear, actionable UI states
• Own the full stack, end to end:
  • Ship features from frontend components through to Node.js services
  • Integrate with our Firebase and AWS DynamoDB persistence layer
  • Manage our AWS infrastructure
• Take prototype code and make it production-quality without needing every edge case spelled out.
• Collaborate with a small, high-ownership team where engineering, product, and design are tightly coupled.

Qualifications

• 5+ years of full-stack engineering experience
• Track record of shipping polished product features in production
• Experience building interfaces that consume AI or ML outputs
• Comfortable owning features from UI through to backend services without a handoff

Requirements

• Built UIs that handle streaming text or progressive AI responses
• Shipped product features involving video, media, or time-based content (a differentiator, not a requirement)
• Worked in small teams with high ownership, moving from prototype to production quickly

Benefits

• Equity options
• Unlimited PTO (we actually take it)
• $200/month wellness stipend
• Health insurance stipend
• Home office budget

The Details

• Location: Remote, anywhere from EST (UTC-5) to UTC+2
