About the Role

The Human Influence (HI) team focuses on the ways in which AI can influence human beliefs, decisions, and behaviour. We are looking for a Research Engineer to join the Human Influence team. Successful candidates will be strong researchers and engineers with a track record of carrying out scalable work in LLM post-training and fine-tuning, especially with Reinforcement Learning; or with comparable expertise in engineering and validating large-scale evaluation pipelines.

Responsibilities

  • Designing and building a Reinforcement Learning environment aimed at mitigating a model’s ability to e.g. deceive a user in a one-to-one conversation or within multi-agent threads.
  • Leveraging state-of-the-art interpretability methods to identify why models exhibit concerning behaviour, and designing mitigations that can be applied to models irrespective of training regime.
  • Building the scalable system architecture underpinning the repeatable delivery and analysis of model evaluations and benchmarks.
  • Delivering ambitious, engineering-heavy research projects on Human Influence topics, for instance by leveraging post-training techniques on a large compute cluster.

Requirements

  • Proven experience deploying a benchmark, evaluation, or product to users, e.g. an evaluations pipeline in an app, an open-source contribution, or similar large-scale contributions to research.
  • Clear understanding of the current AI safety literature, and an interest in topics relevant to Human Influence.
  • Clear and consistent communication.
  • Clear understanding of fundamental Machine Learning concepts.
  • Experience fine-tuning or post-training LLMs using standard methods, using common libraries like PyTorch, Keras, JAX, or custom code.
  • Comfortable working with RL environments and using RL or other reward-based methods to post-train or finetune an ML model, ideally an LLM.
  • Writing scalable and maintainable production code in (at least) Python.
  • Comfortable with serving, scaling, and containerising ML code, e.g. using Docker, Kubernetes, Ray, FastAPI, SLURM, especially on large compute clusters.
  • Good understanding of model internals, e.g. for mechanistic interpretability research, or analysing model activations and weights
  • Experience shipping an AI safety pipeline to production (e.g. evaluations, monitoring, serving custom models), going beyond research prototypes
  • Experience using data to answer complex research questions, e.g. by scoping, training, and validating a classifier or finetuned LLM
  • Experience with frontend and node.js deployments
  • Successful candidates must undergo a criminal record check and get baseline personnel security standard (BPSS) clearance before they can be appointed.
  • Strong preference for eligibility for counter-terrorist check (CTC) clearance.
