Senior Full-Stack Engineer, AI Editing

The Pitch

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, the primary way users communicate with the AI, including agentic loops, streaming response rendering, AI plan previews, and suggested action surfaces.
• Integrate the AI pipeline's outputs into the editor: rendering model plans, handling async results, and 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, the UX that bridges raw video input with AI-ready content.
• 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 end-to-end, from frontend components through to Node.js services to our Firebase and AWS DynamoDB persistence layer to our AWS infra.
• 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

You'd Be a Great Fit If

You Have the Experience:

• 5+ years of full-stack engineering, with a track record of shipping polished product features in production.
• Experience building interfaces that consume AI or ML outputs; streaming responses, async workflows, plan-then-execute patterns.
• Comfortable owning features from UI through to backend services without a handoff.

You've Done Work Like This Before:

• 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.

You Work the Way We Work:

• You care about the craft, the UI & product experience is top priority, not just functional.
• You raise issues early and don't wait to be unblocked.
• You think in systems: how the frontend state, the backend service, and the AI pipeline fit together.
