Job description

Job Summary

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. While the product includes a mobile component, it will not require a traditional mobile app, focusing instead on lightweight, accessible experiences.

This is a great opportunity for someone who enjoys building practical, user-focused solutions with simple yet impactful functionality.

HOW WE WORK

We are a remote-first, cross-functional team focused on building high-quality software through collaboration, agility, and innovation. Our development approach emphasizes:

✅ Daily commits to ensure rapid iteration and continuous improvement.
✅ Autonomous problem-solving, with a bias toward action.
✅ Honest and constructive feedback, fostering a culture of learning.
✅ Agile methodology, with short, incremental development cycles.

WHO YOU ARE

You enjoy building clean, efficient systems that solve real-world problems without unnecessary complexity.
You’re comfortable working across the full stack and can move between frontend and backend tasks with ease.
You prefer pragmatic solutions over over-engineering and thrive in environments with straightforward requirements.
You’re adaptable and can work with evolving clarity, especially in early-stage or loosely defined projects.
You’re collaborative but capable of working independently with minimal oversight.
You have a strong sense of ownership and take pride in delivering reliable, production-ready features.

WHAT WE OFFER

💵 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.

WHAT YOU’LL DO

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.

WHAT YOU BRING

✅ 4+ years of experience as a Fullstack Developer.
✅ Strong experience with React for frontend development.
✅ Solid experience with .NET for backend services.
✅ Hands-on experience with SQL Server or similar relational databases.
✅ Experience building and consuming RESTful APIs.
✅ Familiarity with email/SMS integrations or notification systems (preferred).
✅ Understanding of responsive or mobile-friendly design principles.
✅ Ability to work in environments with minimal UI/UX requirements.
✅ Experience working in Agile teams with Git-based workflows.
✅ Strong problem-solving skills and ability to deliver simple, effective solutions.
