In this role, you will be responsible for a variety of tasks aimed at optimizing the development lifecycle and infrastructure:

• Design, develop and maintain responsive, mission-critical web application interfaces using React
• Build reusable, modular components to ensure code reusability, maintainability, and scalability across the front-end codebase
• Translate UI/UX designs and wireframes into high-quality, pixel-perfect, accessible interfaces
• Integrate with RESTful APIs and back-end services, ensuring efficient data flow and robust error handling on the client side
• Optimize application performance, rendering efficiency, and user experience across different browsers and devices
• Collaborate with cross-functional teams - product managers, UI/UX designers, back-end engineers - to translate requirements into robust technical solutions
• Participate in code reviews, provide constructive feedback, and help enforce high code quality and best practices
• Communicate progress, challenges, design decisions and solutions clearly with team members and stakeholders (both technical and non-technical)

• Experience with design patterns, performance optimization, and secure coding practices on the client side
• Proactive mindset: ability to take initiative, identify technical debts or architectural improvements, mentor junior team members, and help raise the overall team's technical level
• Ability to communicate complex ideas clearly, both to technical and non-technical stakeholders; strong collaboration across teams

Nice to Have:

• Familiarity with CI/CD pipelines and front-end build tooling (Webpack, etc.)
• Experience with complex UI design, data-dense dashboards, performance-sensitive rendering, and advanced responsive design techniques
• Experience with geospatial data, mapping libraries (e.g., Leaflet, Mapbox, OpenLayers, Cesium) or real-time tracking and visualization
• Familiarity with code quality, static analysis or linting tools (ESLint, Prettier, SonarQube)
