Senior Fullstack Developer (AI)

Job Position: Senior Frontend / Full Stack Engineer
Лондон (Велика Британія), віддалено
We are building the App Store for the Autonomous Economy. Agentpunkt.com is a marketplace for AI Agents—digital workers capable of planning, reasoning, and executing complex tasks.
This is not a standard CRUD application. We are building a “Mission Control” interface where users interact with, monitor, and deploy autonomous intelligence. The complexity of our frontend rivals that of IDEs or data visualization platforms.
The Opportunity: Fullstack Frontend and Backend Engineering at the Edge of AI
We are looking for a Frontend-Heavy Full Stack Engineer. While our backend is Python (the standard for AI), the “face” of our intelligence is React.
You will be responsible for translating complex, non-deterministic AI behaviors into a deterministic, smooth, and intuitive UI. You will bridge the gap between raw LLM outputs and human understanding.
You will upskill yourself in:
Streaming UI Architectures: Handling real-time token streaming and “thought process” visualization from agents.
Agentic UI Patterns: Moving beyond “chatbots” to build interfaces for agent supervision, tool approval flows, and multi-agent collaboration graphs.
Generative UI: Building components that can adapt dynamically based on the agent’s needs.
The Stack & Engineering Standards
We operate on a modern, strictly typed stack. We value clean abstractions, reusable hooks, and performance.
Frontend (Primary Focus):
Core: React 18+ (Concurrency features, Suspense
Styling: Tailwind CSS (with clsx/tailwind-merge for component variance)
State Management: Zustand or React Query (for server state synchronization)
Routing: React Router DOM (v6+)
Mobile (Required):
Cross-Platform: You will lead the implementation of our mobile strategy (React Native / Expo preferred) to ensure agents are accessible on iOS and Android.
Backend :
(!) Python: Strong development required
Frontend Challenges You Will Solve
Visualizing the “Black Box”: Agents don’t just give answers; they think. You will build UIs that visualize reasoning steps, plan execution, and memory retrieval in real-time (e.g., collapsible “thought” blocks, confident-score indicators).
Latency Hiding: AI can be slow. You will implement optimistic UI updates and skeleton states to make the application feel instant, even when the model is processing.
Complex State Machines: An agent might be Idle -> Thinking -> Tool Use -> Awaiting Approval -> Finished. You will manage these states on the client side to prevent UI desync.
Mobile Responsiveness: Ensuring complex dashboard data is navigable on a mobile screen.
Who You Are
A React Specialist: You know how the Virtual DOM works. You understand useMemo, useCallback, and why unnecessary re-renders happen.
A Backend Python Specialist
Design-System Minded: You don’t just copy-paste Tailwind classes; you build composable, accessible components that scale.
Mobile-Ready: You have either shipped React Native apps or have a strong desire to master mobile development alongside web.
Curious about AI: You might not be an ML engineer, but you are excited to build the controls for the ML engine.
Requirements
3+ years deep experience with React.
3+years deep experience with Python
Proven ability to build complex layouts with Tailwind CSS.
Experience connecting frontends to Python backends.
Familiarity with Mobile Development flows (React Native, iOS, or Android).
Strong understanding of client-side performance (Lighthouse scores, bundle optimization).
What We Offer
Remote-First & Async: We trust you to manage your time.
Competitive Salary: Top rates for top engineering talent.
The “Agentic” Upskill: You will learn how to build the UIs of the future—interfaces that don’t just display data, but interact with autonomous entities.
How to Apply
Send your CV to Показать контакты or me directly (telegram: Показать контакты) and a link to your GitHub or Portfolio. Highly Recommended: Point us to a specific React component or mobile screen you built that handled complex state or real-time data.
