Front-end Developer – ASP.NET Razor / Bootstrap / Jquery en JGRP

You’ll be joining a team at JGRP, a boutique software agency known for building reliable, thoughtfully crafted web applications for nonprofits, educational institutions, and startups.

The project you’ll work on is a large ASP.NET MVC application with Razor views and a jQuery/Bootstrap frontend, reliability, consistency, and thoughtful improvements matter a lot. You’ll be working closely with our backend developers and project managers to ensure the UI is responsive, functional, and bug-free.

We’re looking for a senior frontend developer who can confidently work within a legacy ASP.NET MVC application and improve the UI without introducing regressions or breaking business logic. The ideal candidate should have:

Core Requirements

• 6+ years of professional frontend development experience
• Strong jQuery skills with experience working in large, DOM-heavy applications
• Solid understanding of ASP.NET Razor Views and ViewModel (@model) binding patterns
• Excellent command of Bootstrap 4/5, especially for layout, responsiveness, and cross-device consistency
• Proficiency with Git and frontend debugging tools (e.g., Chrome DevTools)
• Fluent English writing and speaking skills are a must — you’ll be expected to communicate clearly with the team and document your work as needed

You should be comfortable doing the following:

• Debugging Razor Pages by mapping rendered HTML to the correct ViewModel
• Fixing layout inconsistencies across screen sizes and devices
• Resolving broken JavaScript or jQuery interactivity issues
• Diagnosing whether a bug is caused by CSS, JS, or backend data logic

Bonus Skills (Nice to Have)

• Experience working in large, legacy codebases
• Familiarity with jQuery plugins like Toastr and Select2
• A sharp eye for UI/UX details such as spacing, alignment, and hierarchy
• Understanding of how ViewState, POST/GET binding, and form submission flows work in .NET MVC
• Comfort with backend logic in C# — enough to trace data flow, spot issues, or assist with backend fixes when needed
