- Apply custom styling and theming using CSS/SASS and design tokens to match enterprise visual standards
- Create responsive interfaces and stateful components using React Hooks or Context API
- Contribute to reusable design systems, internal component libraries, and analytics UX guidelines
- Optimize performance and load times, especially for embedded charts and large-scale UI rendering
- Conduct testing, code reviews, and participate in agile development cycles
- Support integration of role-based access, filters, and drill-down actions in embedded visual apps
Nice to Have

- Familiarity with D3.js, Recharts, Plotly, or other front-end charting libraries
- Experience with enterprise BI tools (Power BI, Looker, Tableau)
- Knowledge of authentication patterns (OAuth, Azure AD) in embedding contexts
- Experience working alongside Snowflake, Databricks, or similar cloud data stacks
- Familiarity with data governance, privacy, or analytics use cases in regulated industries (e.g., GxP, SOX)
About You
- 3+ years of experience building modern web applications with React.js
- Strong proficiency in JavaScript (ES6+), HTML5, CSS3, and component-based architecture
- Experience with CSS customization, design systems, and styling libraries (Tailwind, styled-components, etc.)
- Proficient in using React Hooks, Context, and component lifecycle patterns
- Experience integrating with APIs (REST/GraphQL) to drive data visual elements
- Familiarity with embedding analytics dashboards (e.g., Power BI, Tableau, or Looker) via JavaScript SDKs or iFrames
- Ability to work with large JSON data structures and dynamic UI rendering
