VLM Research Engineer (m/f/d)

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.

Your role

• 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

You bring

• 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

Nice to have

• 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
