Our Tech Stack

Flutter is a framework built for fast iteration and pixel-perfect UI across every device and platform (iOS, Android, Web, and Desktop).

• Dart is the programming language used by Flutter. We use Dart for business and core logic. It allows us to “write once, run everywhere” without penalizing performance or expressivity, becoming the common denominator of our Engineering team.
• The Composable Architecture (TCA) is a Redux-like unidirectional data flow architecture, composed of states, actions, and environments.
• built_value, freezed, and Google Protobuf are three libraries we use extensively to model and exchange data across platforms.
• Typescript and Node.js are the two technologies we use for our backend system (login, authentication, and payments).
• Native platforms. Although Flutter & Dart are cross-platform, sometimes we need to implement platform-specific features, requiring native development:
  • For iOS, we use Swift, Metal, and AVFoundation;
  • For Android we use Kotlin, OpenGLES, and Media;
  • And for Web, we use JavaScript and CanvasKit.
• Rendering is done using custom Flutter widgets and native technologies:
  • GLSL or Metal as shading language;
  • AVFoundation for video playback, encoding, and decoding on iOS and macOS;
  • MediaMuxer, MediaEncoder, and ExoPlayer on Android;
  • FFMPEG;
  • We use a custom version of the Flutter Engine (C++), that we develop and maintain continuously.
• Firebase and Google Cloud Platform (GCP).

We Offer

• Competitive pay based on seniority and skillset.
• The latest Apple hardware (Mac, iPhone, and anything else you might need).
• 1-month vacation per year + untracked time off if you need more.
• A diverse and international work environment that operates in English-we come from countries like Italy, Sweden, Brazil, Japan, Hungary, China, Romania, and we want to keep growing!
