Job Description
Senior Frontend Engineer
DEUNA
• Build and maintain production-grade Next.js (App Router) + React + TypeScript applications — dashboards, chat/copilot surfaces, and agentic research UIs. • Design and ship data visualizations (time series, breakdowns, combo charts, KPI strips) with a charting library (we use ECharts) — readable, performant, on-brand. • Craft AI/agent UX: streaming "thinking" traces, multi-step/agent fan-out progress, grounded follow-up conversations, and the rich result artifacts (boards, reports, canvases) users interrogate. • Own and extend a design system — design tokens, reusable components, motion/animation, and accessibility — keeping a large surface visually consistent. • Prototype mock-first for rapid product iteration, then graduate proven flows to real data and APIs. • Care about performance and correctness: React rendering, SSR/hydration, bundle size, and the subtle bugs that come with modern React. • Do light fullstack glue: build and consume REST/JSON APIs, wire up a backend service or BFF endpoint, shape data contracts, and integrate LLM/agent backends. • Keep the codebase healthy: typed, linted, documented, and easy for the next person (human or AI agent) to pick up.
Job Requirements
- 3+ years building web apps with React and TypeScript in production.
- Strong with a modern React framework (Next.js or similar) — App Router, SSR/CSR trade-offs, data fetching, routing.
- Real fluency in CSS / a utility framework (Tailwind) and translating design into pixel-faithful, responsive, accessible UI.
- Experience with data visualization / charting and making dense information legible.
- Solid product instincts — you make sensible UX decisions independently and sweat the details (states, empty/loading/error, motion, micro-interactions).
- Comfortable with Git, code review, and shipping iteratively; you write code that reads like the code around it.
- You can stand up and consume an API — Node/Express or Python/FastAPI — and reason about request/response shapes, auth, and async behavior.
- You're comfortable integrating LLM / agent APIs (streaming responses, tool/function calls) and modeling that on the frontend.
- You don't need to be a backend specialist — but you shouldn't be blocked waiting for one.
- AI-native UX experience: copilots, RAG/agent interfaces, streaming/token-by-token UIs, or "show your reasoning" patterns (nice to have).
- Building or maintaining a design system / component library (nice to have).
- Fintech / payments domain exposure (acceptance rates, routing, fraud, PSPs) — or eagerness to learn it fast (nice to have).
