Senior Frontend Engineer (Conversational & General User Interface)

• Farther’s AI assistant answers advisor questions and drives the product on their behalf — navigating, opening workflows, and more
• This role continues and deepens the interaction between the assistant and our traditional UI platform. Next, it composes the interface itself
• You will contribute to both the framework that makes that possible and the assistant itself
• You are not designing screens, you are designing the system that decides what a screen can be, and the guardrails for the moment it is handed something nobody anticipated
• Deliver the assistant experience, prototype → production — the surface advisors reach for, and the thing every other item on this list exists to make possible
• Build the framework underneath it, so any Farther surface can declare what the agent can do and what it can see in a few lines
• Design the renderer that turns a model’s output into a real, validated, submittable interface, extensible so a new kind of input is additive and never a refactor
• Negotiate and version the wire contract with the agent backend team, and hold both sides to it with tests
• Treat developer experience as a first-class deliverable — design the API, document it, and judge it by how many teams build on it without asking you for help
• Mentor the engineers coming up behind you and set the quality bar in review
