Senior Research Engineer (AI Safety Institute)
The Senior Research Engineer at the AI Safety Institute builds and maintains scientific software to enable high-quality research, bridging software engineering and research. This role involves collaborating with research scientists and the Platform Engineering team, developing bespoke infrastructure and tools for research projects, and working on evaluations of cutting-edge Frontier AI models. Responsibilities include analyzing and visualizing outcomes, managing large datasets, and making trade-offs in code development to support multiple experiments or quickly test hypotheses.
Advances in AI over the last decade have been rapid and surprising, and societal impacts will grow and accelerate. It is our responsibility to inform civil society and support governments in their response. Our institutions need to develop robust and agile safety mechanisms so all of humanity can benefit from the power of Frontier AI models. This is a once-in-a-generation moment.
This role will sit at the heart of government in our new Artificial Intelligence Safety Institute (AISI). The AI Safety Institute is the first state-backed organisation focused on frontier AI safety for the public interest. Its mission is to minimise surprise to the UK and humanity from rapid and unexpected advances in AI, and will work towards this by developing the sociotechnical infrastructure needed to understand the risks of advanced AI and support its governance.
We have a lot of work to do. We want to find great people with a wide range of skills and backgrounds to advance AI safety this year with a global impact. We're particularly interested in building out "safety infrastructure" and developing risk assessments that can inform policymakers and spur global coordination on AI safety. We are dedicated to progressing many aspects of this: from investigating current and future societal harms, over a wide range of misuse risks in areas like cyber and bio, to concerns of losing control of the AI systems we are building. While we have a strong focus on AI system evaluations, we are also spending significant effort on foundational research in the above areas and beyond.
Research Engineers build and maintain scientific software to enable high quality research. They are uniquely placed to bridge the world of software engineering and research and are typically involved in diverse projects.
As a Research Engineer you might be embedding with one (or more) of our research teams. Here you will be collaborating with research scientists and people running evaluations and user studies on the one hand, and with our Platform Engineering team on the other. You might also on-board, run and improve existing evaluations from the wider research community, as well as up-scaling new evaluation methods developed in-house.
The Platform Engineering team will be providing the foundational infrastructure for our research projects. You will build on top of our platform to create bespoke, load-bearing infrastructure and tools for individual research projects. You will be able to independently run and analyse your own experiments to diagnose problems and understand our research work and tech stack in detail.
You will spend your time working not just on infrastructure code but also in the planning and execution of research projects, such as a wide range of evaluations of cutting-edge Frontier AI models. This includes working on analysing and visualising the outcomes of complex evaluation or fine-tuning procedures and managing large data sets.
As a research engineer it is your responsibility to make the hard trade-offs between when code needs to be load-bearing enough to support multiple experiments and when it is better to write “good enough" code to quickly prove or disprove a hypothesis. In this you will work very closely with our Research Scientists who will often be the main users for the tools you build.
This role may be a great fit if you:
