Code and Multimodal Retrieval F/M

About NAVER LABS Europe

NAVER LABS Europe is part of the R&D division of NAVER, Korea’s leading Internet portal and a global tech company with a range of services that include search, commerce, content, fintech, robotics and cloud.

The position

We are looking for an intern to help develop a new family of retrieval models for code and multimodal data. The intern will be responsible for training models on code and multimodal datasets, experimenting with novel architectures, integrating existing data sources, analysing failure cases, and proposing improvements to enhance both performance and latency.

More broadly, our team explores the intersection of search, LLMs, and agents.

We value curiosity and a strong desire for deep understanding, particularly when it comes to model evaluation and experimentation.

The candidate will join the Retrieval and Memory team, which developed the SPLADE family of sparse retrievers. Recent publications from our team include:

• PISCO: Pretty Simple Compression for Retrieval-Augmented Generation (ACL’25)
• Provence: Efficient and Robust Context Pruning for Retrieval-Augmented Generation (ICLR’25)
• BERGEN: A Benchmarking Library for Retrieval-Augmented Generation (EMNLP’24)

About the research team

In the Action group, we develop AI-driven decision-making capabilities that enable embodied agents to safely execute complex tasks in dynamic environments. To achieve autonomy in real-world everyday spaces, robots must learn from their interactions, understand how to best execute tasks specified by non-expert users, and do so in a safe and reliable manner. This requires sequential decision-making skills that integrate machine learning, adaptive planning, and control in uncertain environments, as well as the ability to solve hard combinatorial optimization problems. Our research combines expertise in reinforcement learning, computer vision, robotic control, sim-to-real transfer, large multimodal foundation models, and neural combinatorial optimization to design AI-based architectures and algorithms that enhance robot autonomy and robustness when completing complex tasks in constantly changing environments.

What we're looking for (depending on your career stage)

• Phd or Master Level, strong coding skills required.
• Proficiency with Large Language Models (LLMs) is required, including their training and fine-tuning
• Pytorch, transformers library

What we offer

• Ambitious, multidisciplinary projects with experienced international research teams (30 years research in AI and related fields).

• Flexible work/life balance.

• An equal opportunity employer committed to diversity and inclusion.

• A great location that blends urban life, technology and nature with stunning views of the Alpine mountain ranges (Belledonne, Chartreuse, Vercors).

All applications will be carefully considered, even if not all required skills are met. We value diverse backgrounds and the potential of each candidate, and we offer training to support the development of necessary skills.

NAVER LABS, co-located in Korea and France, is the organization dedicated to preparing NAVER’s future. Scientists at NAVER LABS Europe are empowered to pursue long-term research problems that, if successful, can have significant impact and transform NAVER. We take our ideas as far as research can to create the best technology of its kind. Active participation in the academic community and collaborations with world-class public research groups are, among others, important ways to achieve these goals. Teamwork, focus and persistence are important values for us.

 When applying for this position online, please don't forget to upload your CV and cover letter. Incomplete applications will not be considered.

NAVER LABS Europe is subject to French jurisdiction requiring organisations to stipulate that a job/internship is open to both women and men. None of our jobs/internships are gender specific.
