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.
