About the Role

Join Dex in pushing the boundaries of what's possible with LLMs and browser-native AI. As a 2026 Summer Research Engineer Intern, you will work on cutting-edge problems in agent systems, context handling, and tool use, while collaborating directly with the research team to bring novel approaches to production.

What You'll Build

  • Browser agent and tool-calling multi-agent systems.
  • Evaluation frameworks for memory, efficiency, and accuracy.
  • Memory and personalization layer for workflows.

Requirements

  • Research or work experience with RL environments, LLMs, modern AI frameworks, and/or ML.
  • Experience with prompt engineering strategies.
  • Strong foundation in Python and TypeScript.

Sample Projects

  • Designing and creating tool-calling environments to evaluate and benchmark agent systems.
  • Agentic systems that predict and execute users’ next steps in complex workflows.
  • Mapping user paths on real world software to API functionality and action trajectories.
  • A searchable, self-updating memory store for continuously learning agents.
  • A system to interpret DOM snapshots, mouse click events, and keyboard inputs to select browser actions.
  • A context composer that feeds relevant info into LLM prompts based on user interactions, page content, and memory.
