Generative Media Engineer

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

We're looking for a Generative Media Engineer who loves AI image & AI video models and wants to push the limits of what's possible in AI music video generation. You'll work directly with the founder and core team to design, fine-tune, and productionize the next generation of AI video models and workflows.

If you're 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.

• 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.

• 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.).
• You're 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 we're moving forward.
• Location: You are based in Berlin or willing to relocate.

• 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: We're 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, we'll probably try it.
• Hybrid work in Berlin: Enjoy a mix of in-person collaboration in our Berlin office and flexible time working remotely.

If you're a Generative Media Engineer who lives and breathes AI image/video models and wants to define the future of AI music video creation, we'd love to hear from you.

Apply with:

• A short intro
• Links to your GitHub, portfolio, ComfyUI workflows, or demo reel
• A few sentences about why this space (music + AI + video) excites you
