2026 Summer Research Engineer Intern

Join us in pushing the boundaries of what's possible with LLMs and browser-native AI. You'll work on cutting-edge problems in agent systems, context handling, and tool use, while collaborating directly with our 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.

Dex is a personal CRM that reminds you to keep in touch with the people you would otherwise forget.

Dex helps turn your acquaintances into your allies. Going beyond the superficiality of social networks requires commitment. If you remember to keep in touch thoughtfully, you can turn the interesting person you met at a networking event into a friend that has your back.

I built Dex after failing to keep up with the tools I tried (Airtable, Notion, etc) for relationship management. Installing an actual CRM like Hubspot felt like a wrong fit for my informal relationships -- these people were 'my team,' not customers.

Dex is a lightweight personal CRM that’s easy to stick with. Key to Dex is a Chrome extension that enables you to manage relationships while you’re in Facebook, Messenger, Twitter, and the social apps you already use. Dex can also send you actionable reminders (daily, or based on your calendar events) to log your interactions for next time. By using Dex, you can:

Build stronger relationships, by sending you a nudge to follow-up.
Be more thoughtful, by helping you remember where you left off.
Become a superconnector, by making connections you wouldn’t otherwise remember.
