🧾 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.
The ideal candidate is a self-motivated, multi-tasker, and demonstrated team-player. You will be a lead developer responsible for the development of new software products and enhancements to existing products. You should excel in working with large-scale applications and frameworks and have outstanding communication and aleadership skills.
Responsibilities
- Writing clean, high-quality, high-performance, maintainable code
- Develop and support software including applications, database integration, interfaces, and new functionality enhancements
- Coordinate cross-functionally to insure project meets business objectives and compliance standards
- Support test and deployment of new products and features
- Participate in code reviews
Qualifications
