We are seeking a Front End Software Engineer to design and build production-grade user interfaces for next-generation cybersecurity and data-intensive platforms.

This is a 6-month fixed-term position. You will work as part of a team alongside the client, without being required to work on-site at the client's premises.

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.

• 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.
• 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.
• 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.
• 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.
• Work closely with designers to refine UX and close the loop between design and implementation.
• Translate requirements from product and engineering teams into robust frontend solutions.
• Contribute to PoCs, demos, and integration pilots, and support knowledge transfer with internal and partner teams.
