Aleph Alpha is hiring a senior researcher to advance the architecture and training of its next foundation models. The work covers inference-efficient architecture design, training recipes, optimization and scaling behaviour, and running large distributed training jobs on substantial GPU infrastructure. The posting asks for a strong mathematical foundation, deep knowledge of transformer optimization and training dynamics, hands-on pre-training experience at the billion-parameter scale, and solid software engineering habits — testing, reproducibility, debugging. It is a combined research and engineering role inside the pre-training organization, with regular on-site collaboration in Heidelberg.
