Software Engineer II, Frontend Agentic AI

We are looking for a software engineer to build the interfaces people use to work with autonomous AI workers. You will own the chat experience, memory and context views, live run timeline, and approval flows that keep a human in charge.

About You

• Proven Product Builder: You have built and shipped products that users love and have seen the direct impact of your work at scale.
• End-to-End Ownership: You take pride in owning projects from initial concept to launch and are comfortable wearing multiple hats to get the job done.
• AI & Tech Innovator: You stay ahead of the curve, eager to explore and implement the latest technologies, particularly in AI and LLM front-end paradigms.
• Collaborative Partner: You thrive in a high-bandwidth team environment and work effortlessly with both technical and non-technical partners.
• Driven & Ambitious: You have a hunger for success and want to build at a fast-growing company with big goals.

What you'll be doing

• Build the conversational interface for long-horizon agents: streaming responses, tool calls shown as they happen, pause and interrupt controls, and mid-task steering.
• Design and ship memory management interfaces that let users see what an agent knows, edit or delete memories, and understand what context the agent is using and why.
• Build live agent run views: plans, steps, artifacts, retries, and results, rendered in real time over WebSockets or server-sent events.
• Build human-in-the-loop approval surfaces for agent actions that write to external systems, with clear diffs of what the agent is about to do.
• Build the Worker Builder interface where users design and configure their own digital workers in natural language.
• Manage complex client state for long-running agent sessions: reconnection, optimistic updates, partial results, and failure recovery.
• Create a reusable component library for agentic patterns so every new worker ships with a consistent, polished interface.
• Handle model output honestly in the UI: citations, uncertainty, errors, and empty states that tell the user the truth.
• Work daily with backend and agent engineers to shape the APIs and event streams the interfaces consume.
• Optimize for performance across devices and keep the experience fast while an agent streams thousands of events.

What you'll bring to the role

• 3+ years of front-end engineering experience with deep expertise in React, TypeScript, and modern state management (hooks, context, state machines).
• Experience building chat, copilot, or other LLM-powered interfaces in production.
• Hands-on experience with real-time UIs: WebSockets, server-sent events, streaming rendering, and reconnection handling.
• Strong product sense and the ability to design interaction patterns where no standard exists yet.
• Experience integrating front ends with LLM APIs and handling streamed, partial, and structured model outputs.
• Experience translating designs into fast, polished, responsive production code.
• Strong communication skills and comfort working directly with users to refine the experience.

Benefits

• Health, dental and vision insurance
• 401(k)
• Flexible spending account
• Paid leave (including PTO and parental leave)
