Flutter Developer

Role Overview

At Pratap Group, we aren’t building standard CRUD apps. We are building the command center for our fleet and energy assets. As a Flutter Developer, you will bridge the gap between high-frequency telemetry data streaming from our backend and the end-user. You will own the mobile experience that allows our stakeholders to monitor, troubleshoot, and control physical infrastructure in real-time.

Responsibilities

• Build high-performance, reactive UI components that visualize streaming telemetry (e.g., live vehicle location, power consumption metrics, sensor status).
• Integrate directly with our backend streams to ensure low-latency updates without freezing the UI.
• Design apps that remain functional in low-connectivity areas by implementing robust local caching and sync strategies.
• Use Flutter Isolates to move heavy data processing off the main UI thread to maintain a constant 60/120 FPS.
• Work daily with backend engineers and hardware teams to define API contracts.

Requirements

• Proven experience building apps that consume high-frequency, real-time data streams.
• Deep understanding of BLoC or Riverpod for handling complex state.
• Hands-on experience with WebSocket or MQTT implementations in Flutter.
• Ability to implement custom charts, maps, and interactive visualizations.
• Comfortable working in a high-collaboration, office-first environment.
