Research Scientist

About the Role

Eleos is hiring scientists to do foundational and applied machine learning research into the potential well-being and moral status of AI systems. You will work at the intersection of machine learning, cognitive science, and philosophy of mind, doing original, rigorous research to guide and inform decision-makers at frontier AI companies, policymakers, and the public.

What You’ll Do

• Design and conduct empirical research on foundational topics relevant to the potential well-being and moral status of AI systems, such as LLM preferences and values, the ability of LLMs to introspect, persona vectors, and the representation of valence in LLMs
• Design and conduct applied research on the potential well-being of frontier AI systems (e.g., our prerelease evaluations of Claude Mythos Preview)
• Collaborate with external researchers across the AI welfare and AI safety ecosystems on empirical and conceptual research projects
• Write papers and blog posts and present talks reporting your research

Who We’re Looking For

You may be a good fit if you have:

• Strong interest in understanding the potential well-being of AI systems
• A track record of leading and publishing impactful empirical ML research
• The ability to design, run, and iterate on experiments quickly and creatively, including the engineering skills to implement necessary tooling and infrastructure

Strong candidates may also have:

• Familiarity with existing research on AI welfare and/or safety
• A PhD in computer science or the cognitive sciences
• Significant experience with mechanistic interpretability methods
