Your job is to figure out how to achieve this by designing and building experiences that make complex capabilities accessible with as little effort as possible.
What you’ll do
- Design and build interfaces for human-agent and human-collective interaction across native and web applications.
- Prototype experiences that use context, voice, direct manipulation, and existing workflows to reduce the need for prompts and screens.
- Make the collective’s work understandable and accessible, revealing controls and detail when they help people make a decision.
- Take ideas from working prototypes to polished, reliable products, and test whether they reduce effort for real users.
What you’ll bring
Experience designing and shipping interactive software, with strong engineering skills in Swift and SwiftUI, React and TypeScript, or similar tools. Bring working prototypes and products that show your understanding of human-computer interaction and your ability to simplify complex workflows.

ApplyMember of Technical Staff, InteractionSan Francisco · Full-time · On-site
We believe agents are the most disruptive technology of this decade. Moving from the chat era to the agentic era requires rethinking how people and the collective work together.

- Run experiments with real users to measure understanding, effort, trust, and task outcomes, then turn findings into product changes.
What you’ll bring
Experience designing and building interactive systems, with strong prototyping and software engineering skills. Bring an understanding of human-computer interaction, experience testing ideas with users, and the ability to connect interface decisions to agent behavior.
