Requirements

What You Get to Do

• Design, build, test, and optimize front-end applications for AI-native product experiences.
• Create intuitive interfaces for AI-powered workflows such as copilots, assistants, intelligent search, recommendations, summarization, and guided actions.
• Integrate frontend experiences with LLM APIs, retrieval systems, and backend services.
• Translate product requirements into technical specs — decomposing features into component architecture, API contracts, and edge cases ahead of implementation.
• Own frontend architecture for your module and scale applications for performance, reliability, and maintainability.
• Collaborate closely with product, design, backend, and AI/ML teams to deliver high-quality experiences.
• Instrument product usage, latency, and user interaction metrics to continuously improve AI UX.
• Propose innovative solutions to complex problems with minimal guidance.
• Maintain strong engineering standards for accessibility, security, observability, and performance.
• Stay current with evolving frontend, AI UX, and conversational-interface design patterns.

What You Bring:

• Bachelor's degree in computer science, Software Engineering, or related field.
• 6+ years of experience in front-end application development.
• Strong expertise in React, HTML5, CSS3, JavaScript/TypeScript, and modern build tools such as webpack or Rspack.
• Experience building scalable frontend architectures, including micro-frontends where relevant.
• Hands-on experience creating production-grade UI for AI products or data-rich applications.
• Experience integrating frontend applications with REST/GraphQL APIs and AI services.
• Understanding of AI failure modes and how to design around them — timeouts, low-confidence outputs, hallucinations, and the fallback/moderation UX needed when models or retrieval fail.
• Strong knowledge of accessibility, security, and performance best practices.
• Experience with data visualization libraries such as Chart.js, D3, or Highcharts.
• Experience building and deploying React applications and monitoring application performance.
• Strong sense of product design and the ability to translate Figma designs into polished, responsive experiences.
• Proficiency with Git and modern development workflows.
• Ability to work in a fast-paced environment and manage multiple priorities effectively.

Nice to Have

• Awareness of token/cost-efficient prompt design and the frontend patterns used with multi-agent frameworks (e.g., LangGraph, AutoGen, CrewAI).
• Familiarity with agentic tooling concepts — skills, rules/guardrails, and MCP integrations — and how they surface in frontend UX.
• Familiarity with analytics, experimentation, and product telemetry for AI features.
• UI test automation, preferably using Playwright.
• Experience with enterprise SaaS or workflow software.
• Familiarity with Docker for local development environments
