Senior Frontend Engineer, Conversational & Gen UI

Farther is a rapidly growing RIA that combines expert advisors with cutting-edge technology. They are looking for a Senior Frontend Engineer to build the AI assistant experience and the framework that composes the interface. The role involves delivering the assistant experience, building the underlying framework, designing the renderer, and mentoring engineers.

• 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

• 6+ years building production web applications, including time somewhere the frontend was the product
• Expert-level frontend engineering, where strict typing is how you already work
• Production experience with LLMs — agentic systems, tool calling, streaming responses, conversational interfaces — and a point of view on what an interface owes a user when the model is slow, wrong, or halfway through an answer
• Composition over configuration; modular, scalable frontend patterns are how you think by default
• Distributed systems fundamentals — timeouts, retries, idempotency, failure isolation
• Genuine product instincts — you care about the user experience, and raise ambiguity as a decision rather than absorbing it as a guess
• Fluent in an AI-assisted development loop — building with Claude Code, shipping through Git-based PRs and automated review
• End-to-end ownership and a track record of meeting deadlines
• Strong knowledge-sharing / documentation habit
• Comfortable context-switching across multiple concurrent workstreams

• Learn & grow through book clubs, seminars, and peer learning sessions
• Competitive comp package that rewards impact
• Work alongside some of the brightest minds in fintech
• Ground-floor opportunity at a fast-scaling startup
• Chart your own growth path as we expand
• Full health benefits + 401(k) matching & Roth IRA options
• Unlimited PTO
• An amazing collaborative atmosphere between product, design, and engineering to solve hard problems together
