• Deep expertise in modern architectures: transformers, diffusion, multimodal, generative

• Experience training and adapting large-scale models

• Strong programming skills (Python and or Rust)

• Able to translate research into production systems

Key responsibilities:

• Research and develop novel model architectures for reasoning and representation learning

• Post-train and adapt foundation models for real-world applications

• Design, execute, and analyse experiments across training, evaluation, and scaling
