ReactJS Developer

Job Title: ReactJS Developer

Location: Remote
Type: full time
Experience Required: 3+ years in ReactJS (with strong printing integration experience)

About the Role:

We are seeking a ReactJS Developer to join our team to build and integrate invoice printing functionality in a browser-based application. This is part of a larger system related to election-day POS-style operations, where fast and reliable direct printing of invoices/receipts to thermal and regular printers is essential.

Key Responsibilities:

• Design and develop React components for invoice and bill layouts.
• Implement direct printing functionality from the browser (e.g. using window.print, react-to-print, or native printer SDKs).
• Optimize print layouts for various paper sizes (A4, 80mm thermal roll, etc.).
• Ensure compatibility with USB, Bluetooth, and LAN-connected printers.
• Customize styles using @media print and control page-breaks, font scaling, etc.
• Integrate print workflows with backend APIs (fetching invoice data dynamically).
• Provide fallback methods like PDF generation (jsPDF/PDFMake) where needed.
• Support multiple print modes – silent printing, print preview, and auto-printing.

Must-Have Skills:

• Strong hands-on experience with ReactJS, especially component-driven architecture.
• Proven experience in printing from React apps, especially invoices or receipts.
• Familiarity with printing libraries like:
• react-to-print
• print-js
• jsPDF / html2canvas
• Deep understanding of CSS for print (@media print, page size, margin control).
• Experience working with thermal printers and layout tuning.
• Git and code versioning discipline.

Good to Have:

• Experience in POS systems, billing, or e-commerce applications.
• Familiarity with printer SDKs (Epson, Zebra, etc.).
• Knowledge of WebUSB, WebSerial, or Web Bluetooth (for direct printer comms).
• Basic backend knowledge (Node.js, Express) for invoice generation and formatting.
