MERN Stack Developer

About the job:

Build modern, high-impact web applications as part of a collaborative team that values clean engineering, ownership, and continuous learning. In this role, you’ll work across the full stack—crafting responsive user experiences, designing scalable APIs, and shaping data models that power real business outcomes. You’ll partner closely with product, design, and QA to turn ideas into reliable features, while also contributing to code quality, performance, and maintainability. With an AI-forward mindset, you’ll explore practical ways to enhance user experiences and developer productivity—whether through smart automation, intelligent search, or data-driven features. If you enjoy solving problems end-to-end, writing thoughtful code, and mentoring through example, this is a great place to grow and make a visible impact.
