Original job description

Our Business Technology organization builds secure and intelligent internal platforms that power our global workforce.

In this role, you will bridge the gap between complex LLM orchestration and enterprise user experience, ensuring our internal teams can seamlessly adopt and trust AI-driven tools.

Req.#1090018301

Responsibilities

Design and build end-to-end GenAI-powered applications, emphasizing intuitive web-based UIs and performant client-side API integrations
Develop responsive, accessible frontend interfaces using React, TypeScript, or Vue, engineered for streaming responses and low latency
Build and maintain a library of reusable frontend components, hooks, and design systems for enterprise GenAI applications
Implement LLM-based experiences using frameworks like LangChain or LlamaIndex with leading model providers (OpenAI, Claude, Gemini, etc.)
Collaborate closely with designers and product managers to iterate rapidly on novel AI UX patterns (chat assistants, prompt builders, feedback loops)
Ensure top-tier security, accessibility (a11y), observability, and test coverage across client-side and full-stack implementations

Requirements

Frontend Mastery: 5+ years of production experience with React, TypeScript, or Vue for enterprise web applications
Engineering Seniority: 5–8 years of software engineering experience across the full web stack (frontend UIs, REST APIs, microservices)
AI Application Integration: 2+ years of experience integrating GenAI features, LLM APIs, and prompt UI patterns into web applications
Python & Cloud Services: Strong Python backend development skills and 2+ years of experience consuming/building cloud microservices on AWS, Docker, and REST APIs
Component Libraries: Proven experience building, documenting, and maintaining reusable component libraries, design systems, and custom hooks

Nice to have

Conversational UX & Streaming: Real-time streaming UX patterns (SSE/WebSockets), prompt builders, citations, and summary UI components
Web Accessibility (a11y): Deep knowledge of WCAG 2.1 AA compliance and accessible UI component architecture
LangChain for JavaScript: Client-side or Node.js LangChain, LangGraph, or LlamaIndex orchestration
RAG & Vector Search: Familiarity with RAG pipelines, vector search (Pinecone, OpenSearch), and embedding concepts
AI Evaluation & UX: Experience with AI evaluation tooling, feedback loops, and guardrails in user interfaces

We offer

Extended Healthcare with Prescription Drugs, Dental and Vision, and Healthcare Spending Account (Company Paid)

This posting includes a salary range EPAM Canada would reasonably expect to pay the selected candidate.

In addition, the details highlighted in this job posting above are a general description of all other expected benefits and compensation for the position.

An artificial intelligence system is software that is developed with one or more techniques that can, for a given set of human-defined objectives, using algorithmic information processing, generate outputs such as content, predictions, recommendations, or decisions with varying levels of autonomy (“AI”). Tasks that humans have traditionally done by thinking and reasoning are increasingly being done by, or with the help of, AI to help create efficiencies.EPAM may use AI during the recruitment process, in connection with collecting or processing your personal data. Some (non-exhaustive) examples of tasks that EPAM may use AI for include conducting initial screening, creating transcripts of interviews, and assessing applications/CVs against defined job description criteria to make suggestions to the individuals evaluating your candidacy.Your personal data and the results of any processing are not shared with AI applications outside of EPAM infrastructure. While EPAM may use AI to help create efficiencies during the recruitment process, EPAM does not use AI to make hiring decisions, which is done by EPAM Talent Acquisition and management.
