Role Summary

We are seeking a Frontend Developer to design and build production-grade user interfaces for next-generation cybersecurity and data-intensive platforms. The role is centered on translating design specifications into responsive, high-quality web applications, with emphasis on data-dense views, interactive dashboards, and workflows that make large and complex datasets understandable and actionable.

As part of cross-functional teams, you will work closely with product designers, backend engineers, and data engineers to deliver custom UIs from input designs (mockups and prototypes). Our projects operate across the spectrum of frontend engineering, applied AI, and cybersecurity, where the interface is often the primary way users explore findings, prioritize risk, and drive decisions. As part of this role you will help shape products that are usable, performant, and visually polished.

Key Responsibilities

• UI Development & Design Implementation
• Translate design specifications and prototypes (e.g., Figma) into pixel-accurate, responsive web interfaces
• Build reusable, well-structured components and maintain a consistent design system across the product
• Implement data-dense views such as inventories, detail pages, and interactive dashboards
• Ensure cross-browser compatibility, responsiveness, and accessibility across the application
• Data Visualization & Interaction
• Build interactive tables, filters, and visualizations for large structured and semi-structured datasets
• Integrate charting and visualization libraries (such as ECharts, D3, or Recharts) for analytics and reporting views
• Apply techniques such as virtualization, pagination, and lazy loading to keep data-heavy views performant
• Contribute to conversational and natural language query interfaces where AI-assisted features intersect with the UI
• API Integration & State Management
• Integrate frontend applications with REST/GraphQL backends and streaming endpoints
• Design predictable state management and data fetching, caching, and synchronization strategies
• Handle loading, error, and empty states gracefully for a robust user experience
• Quality & Performance
• Optimize rendering performance, bundle size, and load times across the application
• Write unit, integration, and end-to-end tests for frontend components and user flows
• Participate in code reviews and uphold maintainable, well-documented frontend code
