Mission

Research topics:

• Alignment
• Large language models
• Natural language processing
• Mechanistic interpretability

Applications are invited for a postdoctoral position at EPFL, to be hosted by the Data Science & AI Lab , headed by Prof. Robert West.

We seek a candidate who will lead ground-breaking research projects with the goal of building safe AI that truly cares about human interests.

Instead of viewing alignment as mere postprocessing of pretrained models ("lipstick-on-a-pig alignment"), you will contribute to our agenda of "raising" models that will be continuously aligned throughout the training process, starting from token 1 in pretraining (see here for a high-level vision). To this end, you will combine synthetic data generation, mechanistic interpretability, LLM pre- and posttraining, and model evaluation in novel ways.

Principales tâches et responsabilités

• You will contribute to the Swiss AI Initiative , in particular by incorporating your research results into Apertus , SwissAI’s open, transparent, multilingual language model.
  
  You will work in a stimulating, open, and international research environment consisting of many highly talented and motivated students, embedded in a strong network of academic and industrial collaborators.
  
  Other benefits include a competitive salary (starting at around CHF 88,000 p.a.), an extremely well funded national research system, an office next to a stunning lake and even more stunning mountains, and generous travel support.
  
  Involvement in teaching is possible but not required. Project work with MS and PhD candidates is expected.
