We are seeking a skilled and motivated Full-Stack Developer with a front-end focus to join our growing engineering team. This role is central to the development and maintenance of our web-based platform, which relies heavily on live data visualization, real-time interactivity, and scalable architecture.

The ideal candidate will demonstrate deep expertise in React.js and associated front-end technologies, including PixiJS, ThreeJS, MobX/Zustand, and XState, while also possessing solid backend experience using Node.js (Express), PostgreSQL, and WebSocket technologies.

### Key Responsibilities

- Develop and maintain dynamic, responsive, and scalable front-end interfaces using React.js, MUI, and styled-components.
- Implement interactive graphics and animations with PixiJS, ThreeJS, and optionally Spine for advanced motion design.
- Manage complex client-side logic using MobX, Zustand, and XState (state machines).
- Configure and maintain efficient front-end tooling and build pipelines with Webpack.
- Build and maintain robust backend services and APIs using Node.js and Express.
- Design and manage database schemas, queries, and optimizations with PostgreSQL.
- Implement real-time communication and data handling using WebSockets and Socket.IO.
- Collaborate closely with UI/UX designers, product managers, and other developers to deliver high-quality product features.
- Participate in code reviews, testing (unit/integration), and continuous delivery processes.
- Identify performance bottlenecks and optimize front-end and back-end performance.
- Stay current with industry best practices, technologies, and trends to ensure innovation and technical excellence.

### Required Qualifications

- Proven professional experience as a Full-Stack Developer, with an emphasis on front-end engineering.
- Proficiency in React.js and modern front-end development practices.
- Hands-on experience with PixiJS, ThreeJS, or other WebGL/canvas-based libraries.

- Experience with styled-components and UI libraries such as Material UI (MUI).
- Strong back-end development skills with Node.js and Express.js.
- Solid understanding of relational databases, particularly PostgreSQL.
- Experience implementing and managing WebSocket / Socket.IO for real-time data.
- Familiarity with Webpack configuration and performance optimization.
- Strong understanding of front-end performance tuning and responsive design principles.
- Excellent problem-solving, debugging, and analytical skills.
- Strong communication skills and ability to work effectively in cross-functional teams.

### Preferred Qualifications

- Familiarity with Spine animation tools (for front-end animation workflows).
- Experience with CI/CD pipelines and deployment automation.
- Exposure to cloud platforms such as AWS, Azure, or Google Cloud Platform.
- Understanding of testing frameworks (e.g., Jest, Mocha).
- Familiarity with Agile/Scrum development methodologies.

### What We Offer
