Job summary

EPAM Systems is seeking a Full Stack Software Engineer to drive the evolution of a strategic developer-experience tool that enhances design quality across enterprise products. You will bridge frontend UX with AI enablement, leading MCP server development to host and expose UX rulesets.

As a hands-on engineer, you will expand the React frontend, scale the Node.js backend and microservices, codify guidelines into machine-readable JSON/YAML, and secure cloud deployments.

Qualifications

• Full Stack Engineering: Proficiency in building responsive frontend applications in React.js and high-performance backend services in Node.js/TypeScript.
• MCP & API Development: Deep hands-on experience designing and building Model Context Protocol (MCP) servers, RESTful/gRPC APIs, and custom developer tools.
• AI & Agentic Workflows: Solid understanding of generative AI, LLM APIs, and how AI-assisted coding agents consume real-time external tools and rulesets.
• Rules & Automation Engineering: Proven experience codifying complex logical standards or linting patterns into clean JSON/YAML structures.
• Cloud Infrastructure: Experience deploying, versioning, and managing secure fullstack cloud applications — familiarity with the SAP BTP ecosystem would be a strong advantage but is not mandatory.
• UI/UX Engineering Mindset: High comfort level with web standards (DOM structure, CSS, accessibility) and a strong logical grasp of component design (pages, dialogs, button behaviors)
• Excellent problem-solving skills and attention to detail
• Strong communication and collaboration skills
• Excellent verbal and written communication skills, B2 level of English

Responsibilities

• Architect & Build MCP Servers: Drive the design, development, and implementation of a Model Context Protocol (MCP) server, allowing AI coding assistants and automation workflows to seamlessly query and enforce UX rulesets
• Fullstack Development: Maintain and extend the UX Scanner end-to-end — improving the React.js frontend visual reporting interface while scaling the underlying Node.js backend logic and microservices
• Codify UX Standards: Analyze human-readable UX product guidelines (typography, colors, shell structures, action placements) and translate them into robust, machine-readable JSON/YAML rules
• Host & Secure Cloud Deployments: Manage and deploy APIs, rulesets, and fullstack services securely on cloud platforms, ensuring stable version control and scalable access
• CI/CD & DevTools Integration: Work on developer-focused CLI integrations, IDE plugins, or pipelines that enable shift-left automated design audits
• Expert Collaboration: Partner closely with UX design experts to continuously align machine-readable rules with design specifications, establishing a clean human-in-the-loop workflow
