Nuffield College and the Faculty of Business and Economics (HEC) at the University of Lausanne seek to recruit a Research Engineer to work with Professor Ray Duch (Nuffield College, Oxford) and Dr Sonja Vogt (HEC, University of Lausanne) on the “Talking to Machines” research project funded by the Swiss National Science Foundation.
The Project Engineer position is based at Nuffield College, working closely with the team of scholars in Oxford, the University of Lausanne, and collaborating institutions and partners worldwide. The core duties of the role include: leading the development, release, and maintenance of the project’s open-source Python platform; building and operating infrastructure that supports large agent runs at reasonable cost; building pipelines to turn public social media traces and survey, administrative, and census data into persona representations that condition LLM agents; designing and running evaluations to gauge the validity of synthetic results; developing LLM-guided adaptive experimental designs to enable the implementation of optimal treatments on-the-fly; implementing representation learning and text-as-data pipelines, employing learned representations of complex data for downstream (econometric) models; working closely with team members (data scientists, software engineers, and faculty) to adapt code used for data wrangling, machine learning, and optimisation to the specific needs of projects; and contributing to the workshops and conference programme through which the platform reaches the wider research community.
The successful candidate will hold an advanced degree in Computer Science, Engineering, Statistics or a related field. They should possess excellent Python programming skills and strong software engineering practice; demonstrated experience of building applications on top of LLMS, of running large volumes of LLM inference at scale, and of building and deploying cloud-based infrastructure; and proven capacity to manage work across several projects simultaneously, to learn new skills quickly, and to work well within collaborative and cross-functional teams. Strong communication skills for engaging with technical and non-technical collaborators are essential. Experience of fine-tuning open-weight models using parameter efficient methods, knowledge of a deep learning framework (PyTorch, JAX/FLAX or Tensorflow 2.0) and the Hugging Face ecosystem; experience of LLM observability and cost tracking; and familiarity with experimental and causal methods would be an advantage.
The post is full-time (35 hours per week) and fixed-term for two years, and available from 1 November 2026 or as soon as possible thereafter. The salary offered is £59,133 per annum. The Research Engineer will be employed by and primarily affiliated with Nuffield College where the successful candidate will receive supervision from and report to Professor Ray Duch.
