We’re hiring a ComfyUI Workflow Architect for a Swedish AI Film Production startup.
About company:
We are building the future of animation and digital IP creation. We combine world-class storytelling with cutting-edge AI tools to produce high-quality animated content at scale for YouTube, TikTok, streaming platforms, and global licensing partners. We are now looking for a ComfyUI Workflow Architect — someone who lives and breathes pipeline design, prompt engineering, and multi-model orchestration — to help push our productions to the next level.
What You’ll Be Doing: * Design and optimize production-scale diffusion model pipelines: Image-to-video synthesis architectures * Style transfer, LoRA adaptation, and identity-preserving generation * Multi-stage conditioning systems (depth, pose, optical flow) * High-resolution upsampling and noise reduction pipelines * Develop custom model components: fine-tune ControlNets, train domain-specific LoRAs, implement custom attention mechanisms and conditioning layers * Collaborate with production engineers to ensure visual consistency through latent space control, embedding management, and multi-shot coherence strategies * Integrate ML pipelines with training infrastructure, model versioning systems, and asset management tools
Requirements: * Speaking English on B2-C1 level * Deeply experienced with ComfyUI’s model architecture and node-based inference graphs (required) * Strong foundations in computer vision and diffusion models: DDPM, DDIM, latent diffusion, conditioning mechanisms * Proficient with ControlNet, LoRA, and custom conditioning architectures * Expert in PyTorch/CUDA optimization: memory management, kernel fusion, distributed inference * Strong communicator able to bridge ML engineering and production requirements
Bonus Points For: * Custom PyTorch node/operator development for ComfyUI or contributions to the ComfyUI ecosystem * Published research or novel implementations in generative models, video synthesis, or controllable generation * Model fine-tuning and training pipelines: experience with distributed training, LoRA/DreamBooth workflows, or dataset curation * MLOps infrastructure: experiment tracking, model versioning systems, automated evaluation pipelines * Low-level optimization: custom CUDA kernels, quantization strategies, or inference acceleration techniques * Adjacent pipeline experience: real-time rendering engines, VFX compositing systems, or production asset management * Perceptual quality modeling: experience with CLIP embeddings, aesthetic scoring, or automated quality assessment
Working schedule: 9:00-17:00 European time
Socials package: TBA
