Real-Time Flutter Developer for Hardware-Connected App

Flutter Developer (iOS & Android) – Strong UI, BLE & Realtime

Hi,

We’re looking for an experienced Flutter developer to help us build a high-quality mobile app (iOS & Android) for a connected hardware product.

This is not a generic app. The project involves real-time interaction with a physical device, a strong focus on UI quality, and support for remote control with video and audio.

What you’ll be working on

A Flutter app for iOS and Android

Implementing pixel-accurate UI from our mockups (Figma)

Bluetooth Low Energy (BLE) communication with a custom device

Real-time control features

Remote interaction using video and audio (WebRTC or similar)

Polishing animations, transitions, and overall UX

UI matters a lot here

We already have mockups and a clear design direction.
Your job is to turn those mockups into a polished, production-ready app.

Attention to detail is important:

spacing

typography

animations

responsiveness across devices

If you mainly focus on backend or logic and are not comfortable with UI work, this is probably not the right project.

What we’re looking for

Solid experience with Flutter (real production apps)

Strong ability to implement UI from Figma accurately

Experience with BLE integration in mobile apps

Experience with real-time video/audio is a big plus

Comfortable working independently and communicating clearly

Nice to have (but not required)

Previous work with hardware-connected apps

WebRTC experience

Experience with performance-sensitive or real-time apps

Project details

Freelance / contract

Fully remote

Initial scope: ~3 months (MVP)

Possibility of long-term collaboration if things go well

How to apply

Please send:

Links to apps you’ve built (App Store / Google Play)

Screenshots or short videos showing UI quality

A brief explanation of your experience with Flutter and similar projects

Your availability and estimated timeline

If you enjoy working on high-quality UI, real-time features, and non-trivial mobile apps, we’d love to hear from you.

Best regards,
Ricardo
