Research Engineer / Scientist, Self-Improvement

The role

You will develop methods for agents that self-improve after training. You will work with a team of AI researchers and engineers to advance the field through open publishing of research.

What you will do

• Developing prompt optimization and system prompt learning methods that allow agents to continuously learn from long-horizon tasks
• Developing methods allow agents automatically generate and test out hypotheses in an environment, or seek out and improve their own weaknesses
• Improving the efficiency of learning from long-running agentic tasks
• Designing and running experiments to measure self-improvement scalably

Required qualifications

• Expertise in machine learning, in particular LLMs and continual learning
• Familiarity with agent frameworks and prompt optimization
• Track record of impactful research (breakthrough publications and/or open-source contributions)
• Ability to balance execution speed with empirical rigor
• Real-world impact beyond pure academic work
