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
• Technical Stack

Benefits

• Opportunity to work with a talented team of professionals.
• Drive the success of a venture-backed, rapidly growing firm

• Comfortable context-switching across multiple concurrent workstreams
• Fluent in an AI-assisted development loop — building with Claude Code, shipping through Git-based PRs and automated review
• 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
• Composition over configuration; modular, scalable frontend patterns are how you think by default
• Strong knowledge-sharing / documentation habit
• 6+ years building production web applications, including time somewhere the frontend was the product
• 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
• Expert-level frontend engineering, where strict typing is how you already work
• End-to-end ownership and a track record of meeting deadlines
• Used or extended a framework for agent-to-UI communication, and can say precisely where it stopped being enough
• Built and versioned a component library other teams depended on, and know what a breaking change costs once they have all imported it
• AWS fluency — Lambda, API Gateway, DynamoDB, CloudWatch
• Turned LLMs on how your own team builds: codegen, large-scale migrations, spec-to-code pipelines
• Engineering platform or internal tooling — Vercel, an internal PaaS, or the developer platform at your last company
• Wealth management, financial services, or analytics products dense with numbers people act on — including the craft that keeps them fast: profiling, bundle size, render performance
