Job description

Overview

We are building an advanced WebUI platform that bridges modern web technologies with real-time industrial and scientific systems — including laser equipment, robotics, and distributed process control. You will join a cross-disciplinary team of engineers designing secure, high-performance, and visually elegant interfaces that integrate tightly with backend IPC and database layers.

Responsibilities

• Develop and maintain front-end web applications using React + TypeScript with modern component libraries and design systems.
• Implement Node.js backend services and REST / WebSocket APIs for frontend-backend communication.
• Integrate OIDC (OpenID Connect) authentication and role-based access control.
• Connect to PostgreSQL databases for data retrieval, visualization, and configuration management.
• Interface with RabbitMQ, UDP/TCP IPC channels for real-time messaging, telemetry, and status updates.
• Work within Linux-based development and deployment environments (Docker or native).
• Collaborate with system engineers and UI/UX designers to translate functional and visual requirements into reliable, performant, and maintainable interfaces.
• Participate in code reviews, CI/CD workflows, and technical documentation.

Must-Have Skills

• Frontend
  React, TypeScript, JavaScript (ES6+), HTML5, CSS3, modern UI component frameworks (e.g., MUI, Chakra, Ant Design)
• Backend / Server
  Node.js (Express / Fastify / NestJS), REST API design, WebSockets
• Authentication
  OIDC / OAuth 2.0, JWT, session management
• Database
  PostgreSQL (queries, schema design, ORM such as Prisma or TypeORM)
• Messaging / IPC
  RabbitMQ, TCP/UDP socket communication

  Linux development environment, Git, Docker basics

Preferred / Nice-to-Have Skills

• UI/UX & Design: Figma, responsive design, accessibility (WCAG), component theming
• DevOps: Docker Compose, GitLab CI / GitHub Actions, container deployment
• Data Visualization: Recharts, D3.js, Plotly, or equivalent frameworks
• Realtime / Streaming: WebRTC, SSE, or similar transport layers
• Testing: Jest, React Testing Library, Cypress
• Security: HTTPS, CORS, CSRF, secure token storage
• Performance Tuning: lazy loading, bundling (Vite/Webpack), caching strategies
• Documentation: Markdown, OpenAPI / Swagger specs

Education & Experience

• Master’s or Bachelor’s degree in Computer Science, Software Engineering, Information Systems, or related field.
• 0–3 years of practical experience in web application development.
• Fresh graduates with strong project portfolios or open-source contributions are encouraged to apply.

What We Offer

• Exposure to real-time industrial systems and data-driven engineering.
• Opportunity to learn full-stack development and DevOps workflows.
• Collaborative environment bridging UI/UX design, backend systems, and hardware integration.
• Competitive compensation with fast growth potential for high-performing engineers.
