About REC

REC is a growing consumer app designed to help people discover and recommend great people — including fitness instructors, personal trainers, wellness professionals, and other service professionals.

Think of REC as Yelp, but for people instead of places.

REC is already a working iOS application with an established codebase and development team. We’re looking for a Backend Developer Intern who wants hands-on experience contributing to a real-world production application.

Our Technology Stack

REC currently uses:

  • Ruby on Rails (RoR / Ruby) — Backend
  • Flutter / Dart — Mobile application frontend
  • React.js / JavaScript — Admin and control panel
  • Git / GitHub — Version control and development workflow
  • Firebase and cloud services
  • RESTful APIs and third-party integrations

What You’ll Work On

As a Backend Developer Intern, your primary focus will be REC’s Ruby on Rails backend.

Responsibilities may include:

  • Developing and maintaining Ruby on Rails backend functionality
  • Building, maintaining, and troubleshooting RESTful APIs
  • Working with databases and application data
  • Supporting user authentication and account functionality
  • Supporting features including user profiles, recommendations, search, notifications, and analytics
  • Integrating third-party APIs and cloud services
  • Debugging backend and server-side issues
  • Improving backend performance, reliability, and security
  • Assisting with backend testing and deployment
  • Working with GitHub branches, pull requests, and code reviews
  • Documenting backend systems and development processes
  • Collaborating with our frontend, mobile, UI/UX, and development team

Ruby on Rails experience is preferred but not required. Strong candidates with experience in another backend language or framework who are interested in learning Rails are encouraged to apply.

Familiarity with Flutter/Dart, React.js/JavaScript, Firebase, or mobile app development is a plus, but not required.

Ideal Candidate

You may be a good fit if you:

  • Want real-world backend development experience
  • Enjoy solving technical problems and debugging
  • Are comfortable learning an existing codebase
  • Can work independently while collaborating with a development team
  • Communicate progress and technical issues clearly
  • Are dependable and willing to take ownership of assigned projects
  • Are interested in startups, mobile apps, and building products used by real users

What You’ll Gain

This internship provides the opportunity to work on a real, live consumer application rather than only classroom projects.

You’ll gain hands-on experience with:

  • Ruby on Rails development
  • Production backend architecture
  • APIs and databases
  • GitHub development workflows
  • Cloud services and application infrastructure
  • Debugging real production issues
  • Cross-functional software development
