Senior Full Stack Engineer

This is a remote position.

We are looking for a hands-on Full Stack Engineer to help improve, stabilize, and modernize an existing iOS application currently in production with over 1 million downloads.

This role is ideal for someone who is comfortable working across native mobile development, backend/API integrations, and engineering process improvements. You will help enhance an already successful live product while bringing stronger structure, reliability, and maintainability to the codebase and development workflow.

Our current product is a native iOS app built primarily in Swift, with integrations including REST APIs, Socket.IO/live chat, Firebase, Google Sign-In, Facebook Login, in-app purchases, ads, and CocoaPods-based dependency management.

We need someone who can not only improve features and resolve production issues, but also help establish a cleaner architecture and stronger Git-based version control practices.

• Refactor legacy code to improve stability, readability, and long-term maintainability
• Work across frontend and backend integration points, including:

• Set up and enforce Git-based version control best practices, including:
• branching strategies
• pull requests
• code reviews
• release tagging
• Help migrate the project into a clean and sustainable Git workflow if parts of the codebase are not yet properly versioned
