AI Compositor

Cineflix•Toronto, ON

3d•CA$90,000 - CA$110,000

About The Position

Cineflix is building a newly created AI Production Unit, a focused team rethinking how high-quality content is created at speed. We’re looking for an AI Compositor who can take AI-generated material and push it to a finished, production-ready standard. This is a hands-on role combining AI creation, 3D-supported workflows, and traditional compositing craft — working directly alongside the Creative Technologist to deliver work that holds up on broadcast and digital platforms. You are one of two creators inside the Unit, working in parallel with the Creative Technologist (who leads creative direction). You report to the Creative Technologist / AI Unit Lead. Your role sits between creation and finishing — generating AI imagery and video, resolving issues in near-final shots, and ensuring output meets production standards. You will contribute creatively to how shots are built, while primarily owning execution, refinement, and finishing — ensuring ideas translate into clean, usable, production-ready assets.

Requirements

Experience working with AI-generated image and video tools in a production context
Hands-on capability with ComfyUI and platform-based tools (Runway, Midjourney, Kling, Luma, etc.)
Strong compositing skills (Nuke preferred; After Effects / Resolve accepted)
Working knowledge of 3D tools (Maya, Blender, Cinema 4D, or similar)
Demonstrated ability to fix and refine AI-generated content, not just create it
Experience working with shot-based production workflows and delivery standards
Clear, reliable communication and ability to work under deadlines

Nice To Haves

Experience using 3D scenes as inputs into AI workflows
Experience integrating AI material into live-action or CG pipelines
Familiarity with evolving AI production workflows and tools

Responsibilities

Create AI image and video content using ComfyUI workflows and leading platforms (Runway, Kling, Midjourney, LTX, Luma, Pika, etc.), working alongside the Creative Technologist.
Use 3D as a foundation for controlled generation by building simple 3D scenes (Maya, Blender, Cinema 4D, ZBrush) to guide geometry, perspective, and camera movement where precision matters.
Fix and refine AI outputs by resolving artifacts and inconsistencies (identity drift, temporal flicker, edge issues, etc.) using inpainting, outpainting, and targeted regeneration techniques.
Finish shots using compositing tools (Nuke preferred, After Effects, or Resolve) including integration with live-action and ensuring broadcast-ready output.
Run technical QC and prepare for handoff by validating output quality (colour, motion, codecs, continuity) and preparing footage for downstream editorial teams.
Maintain governance, delivery readiness, and clean handoff by keeping every shot versioned and backed by complete provenance, confirming outputs meet technical delivery specs and creating handoff-ready packages.
Partner closely with the Creative Technologist to align on approach per shot — deciding when to regenerate, fix, or build from 3D — and contribute to efficient, repeatable workflows.
