• Collaborative mindset with experience participating in code reviews.
• Self-motivated learner who keeps up to date with modern JavaScript, React, and Node.js development practices.
• Reliable, accountable, and proactive in identifying and communicating blockers or risks early.

Duties and responsibilities include, but not limited to:

• Translate product requirements, specifications, wireframes, and UI/UX designs into high-quality, production-ready frontend features.
• Design, build, and maintain modern web applications using React and TypeScript.
• Develop reusable, maintainable, and well-structured components that can be shared across features and applications.
• Build responsive, accessible, and intuitive user interfaces that work consistently across modern desktop, tablet, and mobile browsers.
• Convert UI/UX designs into accurate, polished interfaces while maintaining a consistent visual language across the product.
• Implement appropriate application architecture, component composition, state management, routing, data fetching, caching, and form-management patterns.
• Build complex forms and user workflows, including validation, conditional behaviour, multi-step processes, error handling, and user feedback.
• Integrate frontend applications with backend APIs and services, including authentication, file uploads, payments, mapping, notifications, and other third-party services.
• Work with REST APIs and other service interfaces, correctly handling authentication, pagination, validation errors, loading states, retries, failures, and asynchronous operations.
• Implement secure authentication and authorisation flows in conjunction with backend services, ensuring appropriate handling of sessions, permissions, and protected application areas.
• Apply frontend security best practices, including input handling, dependency management, secure browser storage practices, and protection against common web application vulnerabilities.
• Design frontend solutions that accommodate changing requirements and future functionality without unnecessary complexity or excessive coupling.
• Optimise applications for performance, including rendering efficiency, network usage, application loading time, asset optimisation, and perceived user responsiveness.
• Implement appropriate client-side error handling and provide clear useful feedback when operations fail.
• Integrate file and image upload functionality, including validation, progress indication, previews, and error handling where required.
• Implement interactive functionality such as maps, dashboards, data visualisations, search, filtering, dynamic forms, and other rich application experiences as required by the product.
• Work closely with backend engineers to define and refine API contracts, data structures, authentication flows, and integration requirements.
• Collaborate with product owners, designers, engineers, and other stakeholders to clarify requirements and identify practical technical solutions.
• Participate in technical discussions and contribute to decisions regarding frontend architecture, application structure, reusable components, and engineering standards.
• Write clean, readable, maintainable, and appropriately documented TypeScript and React code.
• Write and maintain appropriate automated tests for components, application logic, integrations, and critical user journeys.
• Diagnose and resolve defects reported by users, internal stakeholders, automated testing, or application monitoring.
• Investigate and resolve browser-specific, device-specific, performance, usability, and accessibility issues.
• Refactor and improve existing frontend code to reduce technical debt, improve maintainability, and simplify future development.
• Review code contributed by other developers and provide constructive feedback on correctness, maintainability, usability, security, and overall engineering quality.
• Participate in source-control and code-review processes, including producing meaningful commits, pull requests, and supporting technical documentation.
• Work effectively within automated build, testing, deployment, and CI/CD processes and assist in diagnosing issues affecting frontend releases.
• Ensure frontend applications are configurable across local, development, staging, and production environments without embedding environment-specific configuration in application code.
• Maintain awareness of modern React and TypeScript development practices and recommend improvements where they provide clear technical or product value.
• Take ownership of assigned features from initial requirements through implementation, testing, deployment, and ongoing maintenance.
• Contribute to the continued improvement of frontend engineering standards, development practices, tooling, and overall product quality.
