About the Job

Requirements

  • A strong reel, portfolio, or body of work demonstrating visual judgment and technical problem-solving ability.
  • Practical experience applying machine learning, computer vision, or generative models to images, video, geometry, or other related media.
  • Strong Python knowledge and experience developing maintainable production tools.
  • Familiarity with Git, APIs, package and environment management, and reproducible development practices.
  • Experience with a machine learning framework such as PyTorch or an equivalent framework.
  • Practical knowledge of model inference, datasets, evaluation, fine-tuning, and GPU processing.
  • A strong understanding of production imagery, including color, dynamic range, resolution, compositing requirements, and temporal consistency.
  • Strong visual judgment and the ability to respond constructively to creative direction.
  • A generalist mindset and the ability to work across creative, technical, and pipeline challenges.
  • The ability to clearly explain technical ideas and limitations to artists, supervisors, and production teams.
  • Full professional spoken and written English proficiency, with confidence collaborating across international teams and time zones.
  • Candidates must reside within the European Union during the role; Spain is preferred but not required.
  • Candidates without a traditional VFX background may be considered if they demonstrate an exceptional record of relevant applied machine learning, a strong visual portfolio, and a clear understanding of the quality and control required for professional image production.

Responsibilities

  • Work with the Machine Learning Supervisor, VFX Supervisors, department leads, artists, and Pipeline teams to identify practical machine learning applications in production.
  • Prototype, adapt, fine-tune, and evaluate approved machine learning models for image, video, geometry, and asset workflows.
  • Develop artist-friendly tools, nodes, scripts, interfaces, and APIs that connect machine learning systems with established VFX applications and pipelines.
  • Apply machine learning workflows directly to shots, sequences, or assets when appropriate while maintaining artistic control and production standards.
  • Translate creative and production requirements into practical technical solutions.
  • Evaluate workflows for visual quality, temporal consistency, color integrity, resolution, controllability, editability, performance, and reliability.
  • Design representative tests, compare approaches, and document results clearly.
  • Identify failure cases and help define when a model or workflow should and should not be used.
  • Resolve visual artifacts and technical issues, iterating with artists until results meet the creative brief.
  • Prepare authorized datasets and evaluation material for testing, training, or fine-tuning.
  • Create reproducible, versioned, and documented workflows rather than one-off demonstrations.
  • Participate in code reviews and follow architecture, development, and deployment standards established by the Machine Learning Supervisor and Pipeline teams.
  • Support artists using machine learning tools and help turn successful prototypes into stable production workflows.
  • Contribute to internal documentation, demonstrations, and training.
  • Follow studio requirements for client confidentiality, data security, approved models, dataset provenance, and commercial licensing.
  • Collaborate effectively with teams across departments, studios, and time zones.

Desired Qualifications

  • Professional production experience as a VFX artist or artist-oriented technical director in at least one department.
  • Experience integrating tools into at least one major VFX application or production pipeline.
  • Experience with Nuke, Houdini, Maya, Blender, Unreal Engine, or other VFX and digital content creation applications.
  • Experience with ComfyUI or other node-based machine learning workflow systems.
  • Experience with OpenCV, Diffusers, or other computer vision and generative media frameworks.
  • Experience with C++, CUDA, or model and inference optimization.
  • Experience with Linux, containers, cloud infrastructure, or render farms.
  • Experience with USD, OpenColorIO, ACES, EXR, and high-dynamic-range image workflows.
  • Experience with segmentation, rotoscoping or matting, tracking, depth estimation, reconstruction, inpainting, relighting, denoising, or upscaling.
  • Experience with video generation, optical flow, and temporal consistency techniques.
  • Experience preparing datasets, training models, or distributed inference.
  • Experience developing artist interfaces or web development.
  • Open-source contributions, publications, or research with a clear application to VFX production.
