Generative Media Engineer (AI Video & AI Image Models)

At neural frames were building a first-of-its-kind interface that helps musicians and AI artists create AI music videos. Were a very fast-growing profitable AI startup based in Berlin and we live at the frontier of generative video music and visual storytelling.

Were looking for a Generative Media Engineer who loves AI image & AI video models and wants to push the limits of whats possible in AI music video generation. Youll work directly with the founder and core team to design fine-tune and productionize the next generation of AI video models and workflows.

If youre excited about ComfyUI graphs diffusion models video pipelines and agentic workflows - and you want your work to shape how thousands of artists create visuals for years to come - this role is for you.

Tasks

• Manipulate and fine-tune AI video models (and image models where needed) to power our music video and video generation features.
• Curate build and maintain datasets for training and fine-tuning: collecting cleaning tagging and evaluating data quality with a strong eye for visual and stylistic consistency.
• Prototype and productionize agentic workflows for generating full AI music videos end-to-end (storyboarding shot planning style control lip sync motion consistency etc.).
• Build and optimize ComfyUI (or similar) pipelines for internal experimentation and where useful user-facing tools.
• Stay on top of the open-source generative media ecosystem (ComfyUI nodes new diffusion/video models control techniques schedulers etc.) and bring the best ideas into our product.
• Collaborate closely with our engineers to ship models into production: packaging inference optimization GPU performance monitoring and safety guardrails.
• Define and improve evaluation metrics & tooling (quantitative and qualitative) for visual quality temporal coherence and user-perceived wow.
• Work with the founder and product team to explore new creative capabilities (e.g. style transfer camera motion character consistency audioreactive visuals) and turn them into features that artists actually use.

Requirements

• Strong Python skills and experience working with deep learning frameworks (ideally PyTorch).
• Hands-on experience with AI image and/or video generation: diffusion models video diffusion control networks or similar architectures.
• Practical experience with ComfyUI or comparable node/graph-based generative tooling (e.g. custom nodes complex graphs automation).
• Experience in at least one of the following:
  - Fine-tuning or training diffusion or video models
  - Building custom inference pipelines for generative image/video
  - Designing automated/agentic workflows around generative models
• Comfort working with GPU-based workloads (e.g. VRAM constraints batching mixed precision model pruning/quantization etc.).
• Youre excited about the creative side of the work: music videos visual storytelling motion style and aesthetics matter to you.
• You enjoy a fast-paced startup environment: you iterate quickly own projects end-to-end and are okay with some chaos as long as were moving forward.
• Location: You are based in Berlin or willing to relocate.

Benefits

• Shape the frontier of AI music videos: Your models and workflows will directly define what thousands of artists can create with neural frames.
• High impact low bureaucracy: Small focused team. You ship things that matter quickly.
• Work with people who care about art & tech: Were an arts-driven creator-obsessed team that genuinely cares about the visuals not just the metrics.
• Profitable fast-growing AI startup: Rare combination of real revenue real users and room to experiment.
• Autonomy & ownership: Drive your own roadmap inside a clear product context. If you have a strong idea well probably try it.
• Hybrid work in Berlin: Enjoy a mix of in-person collaboration in our Berlin office and flexible time working remotely.
