[Hiring] Portal Front-End Developer @Rad Hires

Role Description

Our client is working with a new end-client to build a user portal linked to a new Shopify website experience. The engagement covers two workstreams: a user portal sitting behind login authentication, and an admin portal acting as a lightweight CMS for user management. You'll work alongside a backend developer (who owns the API build and deployment) and a separate developer handling the Shopify build in parallel. The team is working to an MVP mindset, and you'll have the chance to review and approve final designs before development starts to validate scope. There's potential for further work in a phase 2 build for the right person.

What You'll Do

• User Portal (13 days)
  • Build the frontend components of a 12-week brain health program, including a weekly participant questionnaire
  • Implement progress visualisation via graphs that update weekly on questionnaire completion
  • Build logic for new programme content unlocking weekly alongside brain health tools
  • Implement authentication, onboarding, and protected routes
  • Build the weekly questionnaires and programme content screens
  • Handle loading, validation, empty, and error states
  • Integrate the frontend with the Core API per agreed API contracts
  • Add automated tests for critical participant journeys
• Admin Portal (2 days)
  • Re-purpose components from the user portal workstream to support limited operational user management (e.g. blocking/unblocking accounts)
  • Reuse relevant user portal components for viewing participant information
  • Note: editorial content management is handled separately via Payload CMS — this is not in scope
• QA, Client UAT & Deployment (3 days, over an elapsed 1 week)
  • Work with the internal QA team and external client team to resolve issues flagged via ClickUp
  • Respond to client UAT feedback through the same process
  • Assist with hosting and deployment to a live AWS environment (deployment ownership sits with the backend developer)

Qualifications

• Strong understanding of React development
• Experience with Next.js and TypeScript
• Experience building authenticated, API-driven applications
• Experience with responsive, accessible UI development
• Experience with charts/data visualisation
• Frontend testing experience (e.g. React Testing Library, Playwright)
• Ability to flag risks ahead of time and contribute to mitigating solutions
• Strong communication skills, comfortable working closely with backend, design, and QA teams

Logistics

• Duration: 18 days across a 4-week period, 8 hours/day
• Working hours: 9:30am – 6:00pm UK time, Monday–Friday
• Cadence: Minimum weekly internal project catch-up, scheduled at a time to suit the contractor and team
