• Experience using AI coding tools (e.g. Copilot, Cursor, Codex, Claude Code) in your workflow
• Good spoken and written English

What You'll Do

• Build and maintain reusable JavaScript/React components as part of our design systems
• Turn complex data into clear, interactive visualizations and graph networks
• Optimize rendering performance for large datasets
• Work closely with designers to ship pixel-perfect, accessible interfaces
• Integrate frontends with REST/GraphQL APIs
• Write clean, tested, well-documented code and take part in code reviews and Agile ceremonies

• A systems thinker who builds reusable, scalable solutions
• A clear communicator who works well with designers, developers and product managers
• Organized, adaptable and comfortable with ambiguous requirements
• Curious and quick to learn new tools and technologies

We are offering
