🧾 PDF Generation Developer

Full-time / Remote

We're looking for a junior or entry-level developer to join our team full-time and help us build and generate PDF documents quickly and efficiently using PDFmake.

This is a focused, straightforward role that involves converting structured data into clean, formatted PDF reports — such as financial summaries, client forms, or templated documentation.

While the work is a bit repetitive and requires attention to detail, it's an ideal position for someone who enjoys consistency, works well independently, and wants to gain real-world development experience in a production environment.

Experience with generating PDFs is not required — it's a simple, and you’ll quickly learn everything you need while working with us.

✅ What You'll Be Doing

• Use PDFmake to build and generate PDF documents from JSON or templated data
• Write clean and reusable code for repeated document structures
• Make small adjustments and fixes to existing PDF templates
• Occasionally assist with basic front-end (React) or back-end (NestJS) tasks — very minimal

🛠 Basic Requirements

• Solid knowledge of JavaScript or TypeScript
• Some hands-on experience with PDFmake or similar libraries (please share examples if available)
• Basic understanding of React and NestJS (enough to navigate and make small changes)
• Able to write clean, maintainable code with minimal supervision
• Good understanding of layout/positioning concepts (coordinates, grids, etc.)

🤝 Soft Skills We're Looking For

• Reliable, consistent, and self-motivated — you enjoy completing tasks without much variation
• Good communication in English (written and verbal)
• Organized and responsive — this role requires clear updates and attention to formatting details
• Open to feedback and iterative improvement

💼 What We Offer

• A stable, remote full-time role with consistent tasks
• Opportunity to improve and learn through production code
• Supportive and flexible team culture
• Note: This is a low-complexity role with a modest salary, ideal for someone early in their career or looking for focused, stable work.
