[Hiring] Front End Software Engineer @CENSUS SA

Role Description

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).

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.
• Collaboration & Delivery
  • 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.

Qualifications

• BSc/MSc in Computer Science, Software Engineering, or related field (or equivalent practical experience).
• 4+ years of experience in frontend or full-stack development, with a strong focus on the frontend.
• Strong proficiency in JavaScript and TypeScript, and modern HTML5 and CSS3.
• Hands-on experience with a modern component-based framework (React preferred; Vue or Angular also considered).
• Proven experience translating design mockups and prototypes into production-quality interfaces.
• Solid understanding of responsive design, cross-browser behavior, and web accessibility.
• Experience integrating with REST or GraphQL APIs and managing application state.
• Familiarity with modern frontend build tooling and version control with Git.
• Strong problem-solving, debugging, and communication skills.
• Proficient in English and excellent communication skills.

Preferred / Nice-to-Have Skills

• Experience building data-dense interfaces, operational dashboards, or analytics tooling.
• Familiarity with data visualization libraries (D3, ECharts, Recharts) and large-table performance techniques.
• Experience with design systems and component libraries (e.g., Storybook).
• Exposure to BI / analytics platforms such as Superset, including embedding or extending their UIs.
• Experience building chat or conversational UIs for AI/LLM-powered features.
• Knowledge of security concepts or experience working on cybersecurity products.
• Familiarity with containerization (Kubernetes) and CI/CD workflows.
• Experience with testing frameworks (Jest, Playwright, Cypress) and frontend observability.
