Job Description

Role Description

20four7VA is seeking offshore independent contractors to deliver remote services to clients worldwide, with a primary focus on developed markets such as the United States, the United Kingdom, Canada, and Australia. The client is seeking a mid-level Front-End Developer Virtual Assistant with strong React experience to support the development of its proprietary permit automation platform. The developer will work on improving and expanding the front-end interface to support permit technicians, clients, and internal teams. The candidate will report directly to the lead developer.

Note: This is not a junior-friendly codebase. We are looking for a minimum mid-level candidate who is comfortable working within a large, existing production codebase from day one.

The objective of each engagement is to assist the client in improving business efficiency, enhancing service delivery, or supporting operational functions through high-quality, task-specific services rendered by a qualified contractor.

Qualifications

  • Strong React 18 experience: hooks, functional components, context API
  • Redux Toolkit (RTK): slices, async thunks, selectors, real-world state management
  • Material UI v6: deep familiarity including theme customization, responsive design, and MUI X components
  • React Router v6: complex route trees, guarded/protected routes, nested layouts
  • Solid JavaScript (ES6+) knowledge: async/await, Promises, error handling (codebase is JS, not TypeScript)
  • WebSocket experience: connection management, message dispatching, React integration
  • Axios and REST API consumption
  • Proficient with Git and version control: branching, PRs, merge conflict resolution
  • Comfortable reading and working within a large existing codebase (not greenfield only)
  • Strong communication and async remote collaboration skills

Requirements

  • Contractors will be required to provide services that align with the following client tasks:
    • Front-End Development
      • Develop and maintain front-end features using React 18 (functional components, hooks)
      • Build and improve UI components using Material UI v6 including MUI X (DataGrid, DatePickers)
      • Implement new features from clearly defined Linear tickets with acceptance criteria
      • Work within Redux Toolkit architecture (slices, async thunks, selectors)
      • Maintain and extend WebSocket-based real-time features
      • Manage complex routing with React Router v6 (guarded routes, multi-role layouts)
    • Platform Support & QA
      • Conduct regression testing on new features before staging deployment
      • Work closely with the lead developer to understand API contracts and backend responses
      • Debug and resolve UI performance issues (memoization, render optimization)
      • Maintain clean, well-documented, readable code
    • Permit Forms & Product Work
      • Build and maintain permit form templates within the platform (building permits, electrical permits, NOCs, legal descriptions, and other municipal/legal documents)
      • Support the forms digitalization pipeline (AI-assisted PDF form processing)
      • Provide recommendations for improving usability and workflow efficiency
    • Technical Debt & Migrations (when feature work is quiet)
      • Assist with incremental migration from JavaScript to TypeScript
      • Assist with migration from Create React App (CRA) to Vite

Benefits

  • Competitive rates
  • Weekly payments
  • Various open roles are available
  • Free training and upskilling
  • Constant support and guidance
  • A vibrant community always ready to support you
  • And more!

Work Schedule

  • Contracted Hours per Week: 40 Hours
  • Scheduled Working Days: Monday through Friday
  • Daily Working Time: TBD EST (Standard US Business Hours)

Terms of Engagement

  • Contractors will operate under a Master Services Agreement and a Statement of Work
  • This is not an offer of employment; contractors are not employees of 20four7VA or any client
  • All compensation is processed through 20four7VA according to the terms of the engagement
