About the RoleThis is a fully remote senior, pipeline-owning role. You'll set the technical direction for how CoSA uses generative video across shows - building the tooling, making the model and infrastructure calls, and elevating the work of the artists who depend on it.
What You'll Do- Architect, build, and maintain the studio's production-grade ComfyUI pipelines and reusable workflow templates.
- Own model strategy: evaluate and integrate new video models as they ship, and decide what belongs in the pipeline.
- Solve the hardest problems - temporal stability, character and identity consistency across shots, motion control, and seamless integration of generated elements into live-action.
- Develop custom nodes and automation to speed up iteration across multiple productions.
- Manage local GPU inference, model weights and LoRAs, and VRAM/throughput tradeoffs against production deadlines.
- Partner with VFX supervisors and creative leads to translate director intent into reproducible technical setups.
- Mentor generalists and artists, and document pipelines so the work is repeatable and not locked in one person's head.
What You'll Need- Deep, demonstrated mastery of ComfyUI and Griptape - complex custom graphs, conditioning, control mechanisms, and debugging difficult node trees.
- Broad, current fluency across video models, including local open-source options (Wan 2.2 / 2.6, LTX-2, HunyuanVideo) and the leading proprietary models (Kling 3.0, Google Veo 3.1, Runway Gen-4.5, Seedance 2.0, Luma Ray3).
- Strong command of image-model control tooling (ControlNet-style conditioning, LoRAs, IP-Adapters, inpainting) as it feeds video.
- Python scripting for custom nodes and automation.
- Real VFX fundamentals and an understanding of how generated content integrates with a traditional pipeline (compositing, rotoscoping, color).
- Experience managing local GPU environments (CUDA, model and dependency management).
Strongly Preferred- Prior senior, TD, or lead experience at a VFX or animation house.
- Experience training or fine-tuning custom models and LoRAs.
- Familiarity with API-based generation pipelines and batch processing.
- Experience with Nuke and a broader post pipeline.
Who You Are- A builder and problem-solver who can untangle a pipeline without a roadmap.
- Current by instinct - you track the landscape and know which tool fits which shot.
- A force multiplier whose work makes everyone around them faster and better.
