Ai jobs in Germany

We’re looking for a Research Engineer to push the limits of vision-language models for real-world video understanding. You’ll work on applied, state-of-the-art multimodal models and turn them into production pipelines used by customers.

• Design and adapt vision-language and video models for scene understanding, temporal reasoning and activity / action recognition
• Build and maintain large-scale training and evaluation pipelines on GPU clusters
• Curate and augment video-text and action datasets, including synthetic labels and retrieval-based augmentation
• Develop robust benchmarks for video QA, instruction following and temporal understanding, and use them to drive iterative model improvements
• Cut and refactor model architectures for efficiency and deployability (compression, pruning, distillation)
• Deliver production-ready inference pipelines to product and customer teams, working closely with CV, platform and robotics engineers

• Completed PhD (or equivalent research track record) in computer vision, machine learning, robotics or a related field
• Strong background in video-centric deep learning: scene understanding, temporal / activity / action recognition, or video generation
• Experience training and adapting large vision or VLM models (e.g. InternVL, Qwen-VL, DeepSeek-VL, similar stacks)
• Proven work with multi-GPU training (PyTorch, distributed, mixed precision) and large-scale datasets
• Solid engineering habits: clean Python, reproducible experiments, reliable data and training pipelines
• Track record of moving research into usable systems (demos, internal tools, or productised features) in fast-moving teams

• Publications at top-tier venues (CVPR, ICCV, ECCV, NeurIPS, ICLR, etc.) on video, multimodal learning or scene understanding
• Experience with 3D/4D scene representations, action generation or embodied / sense-plan-act style projects
• Inference optimisation: quantisation, TensorRT, model distillation, or deployment on constrained hardware
• Prior experience in a startup or applied research lab environment

• A competitive salary & stock options*
• Be on the forefront in defining what artificial intelligence means in manufacturing
• Gain hands‑on experience in working in an AI‑first software company
• Supportive and inclusive culture that values diversity and promotes the advancement of underrepresented groups within the company
• Collaborate with a diverse (currently more than 10 nationalities) and talented team, working on cutting‑edge projects with real‑world impact
• Network with professionals and leaders in the field, opening doors to potential future career opportunities
• We have a very flat hierarchy, open 360° feedback, and flexible working hours
• Ethics⚖: We are committed to developing ethical AI software
