Perplexity offers a 12- to 24-week full-time internship in its Berlin office for a machine learning research engineer. Work covers search quality: training and optimising deep learning models in PyTorch with distributed training and hardware acceleration, for retrieval and ranking; representation learning research such as contrastive and multilingual methods; and RAG pipelines for grounding and answer generation. The posting asks for knowledge of search and retrieval evaluation, strong PyTorch skills, interest in representation learning, and a publication record at venues like NeurIPS, ICML, ICLR, ACL, EMNLP or SIGIR.
