• Integrate, process, and visualize data from multiple sources, including live streams and archived datasets.

• Collaborate with backend engineers, product managers, and UX/UI designers on feature design and implementation.

• Contribute to code reviews and follow established frontend best practices and architectural patterns.

• Help ensure frontend systems are reliable and maintainable through testing and documentation.

• Contribute to reusable components and shared frontend libraries.

What Will Make You Successful

• 5+ years of experience building user-facing web applications, or equivalent experience through internships, projects, or coursework.

• Experience with React, TypeScript, JavaScript, state management, and modern web standards (HTML/CSS).

• Familiarity with asynchronous frontend patterns and working with APIs or data streams.

• Strong problem-solving skills and eagerness to learn from feedback and mentorship.

• Ability to work effectively in a collaborative, fast-moving environment.

• Attention to code quality, performance, and maintainability.
