Winmill Software

Role Description We are looking for a Fullstack Developer to help build a mobile membership card solution that enables users to receive, store, and access digital membership cards seamlessly—similar to how ticketing platforms deliver passes directly to a user’s phone wallet. In this role, you’ll work across the stack using React (frontend), .NET (backend), and SQL Server, contributing to a streamlined system that generates and distributes digital cards via email or SMS.

Requirements - Build a Digital Membership Card System – Develop functionality to generate and distribute digital membership cards. - Develop Frontend Features – Use React to create simple, user-facing components for card access and interaction. - Build & Maintain Backend Services – Implement APIs and business logic using .NET. - Manage Data Storage – Work with SQL Server to store and retrieve membership and card data securely. - Enable Card Distribution – Integrate email/SMS workflows to deliver cards to users. - Ensure Mobile Compatibility – Optimize experiences so cards can be easily saved to mobile wallets. - Collaborate with Internal Team – Work closely with engineers and stakeholders to align on functionality and delivery. - Support Testing & Delivery – Partner with internal team members for validation and iteration. Benefits - 💵 USD Salary Compensation - 🌍 100% Remote Work – Work from anywhere! - 📈 Exciting, Diverse Projects – Work on impactful, real-world solutions. - 🚀 Career Growth Opportunities – Expand your fullstack expertise across projects. - 🤝 Supportive & Agile Team Environment – Collaborate with experienced engineers. - 👊👊 Team Building Activities – Be part of a community that values connection and collaboration.
