Overview

Perplexity is offering an Internship Program for a Machine Learning Research Engineer based at the Berlin office in Germany. This is a full-time, in-person internship lasting between 12 and 24 weeks. The position focuses on advancing search quality through models, data, and tools.

What you get

The internship program offers hands-on experience working directly in the Berlin office for a duration of 12 to 24 weeks on a full-time basis. Interns will engage in training large-scale deep learning models and conducting research in representation learning.

Requirements

Applicants must have an understanding of search and retrieval systems, including quality evaluation principles and metrics. Strong proficiency with PyTorch is required, including experience in distributed training techniques and performance optimization for large models. Candidates should be interested in representation learning, such as contrastive learning, dense and sparse vector representations, representation fusion, cross-lingual representation alignment, training data optimization, and robust evaluation. A publication record in artificial intelligence or machine learning conferences or workshops, such as NeurIPS, ICML, ICLR, ACL, EMNLP, or SIGIR, is also expected.
