Matrixspace is hiring: Senior UI/UX Developer Lead in Burlington

This role is perfect for a builder at heart — someone who enjoys wearing multiple hats, thrives in a dynamic environment, and can take ownership of both technical design and user experience. You will lead UI/UX development efforts, mentor junior engineers, and collaborate closely with product and backend teams to deliver beautiful, functional, and scalable interfaces.

Key Responsibilities

• Design interactive prototypes and flows using Figma, ensuring seamless user experiences and visual consistency.
• Collaborate with backend teams to integrate RESTful APIs and Node.js services.
• Implement and manage OAuth-based authentication, session management, and secure user workflows.
• Work on data visualization components including maps, charts, and tables using tools like Recharts, D3.js, ECharts, or Mapbox.
• Ensure high performance, accessibility, and scalability of all frontend components.
• Provide technical leadership and mentor a small development team in best coding and UX practices.
• Stay current with the latest frontend technologies and contribute to the overall technical vision of the product.

• Experience developing data visualizations using libraries like Chart.js, D3.js, Recharts, or Mapbox.
• Exposure to UX design principles, usability testing, and performance optimization.
