We’re looking for an experienced Bluetooth Low Energy Expert to join our team as a freelancer immediately. If you have a strong commercial background in BLE, IoT, and mobile development (iOS, Android or Flutter), and you can independently implement BLE solutions in real projects, we want to hear from you.

As a specialized software house, we work on innovative IoT solutions for top-tier clients like Oura, BOSE, and McIntosh. This is an opportunity to work on a high-impact project where your deep BLE knowledge will be critical.

Our next project in this area is kicking off in January/February, so we’re starting the search now to bring the right person on board in time.

Who we’re looking for:

Proven commercial experience with BLE – deep understanding of communication protocols, peripheral connections, and troubleshooting.
Strong mobile development skills – expertise in either iOS (Swift, Core Bluetooth), Android (Kotlin, BLE APIs) or Flutter (Dart, BLE packages).
Experience in IoT – working with connected devices, sensors, and embedded systems.
Solid knowledge of Unit Testing and best practices in mobile development (XCTest, Quick/Nimble for iOS; JUnit, Mockito for Android or Flutter test frameworks).
Familiarity with concurrency and performance optimization for BLE applications.
Fluent English (B2+) – written and spoken.

Nice to have:

Experience with Bluetooth 5+ and advanced BLE features (Long Range, Mesh).
Previous work in IoT security and encrypted BLE communication.
Understanding of functional reactive programming (RxSwift, Jetpack Compose, or Flutter’s reactive state management approaches like Riverpod/Bloc).
Knowledge of Google Play/Android Auto, Apple MFi programs, or Flutter’s app distribution and integration processes.

What we offer:

Fully remote and flexible work with core hours between 10:00 and 18:00 CET, with some client meetings scheduled up to 20:00 CET (approx. 2 per week).
Competitive freelance B2B rate (15-30k net, depending on experience).
The chance to work on a cutting-edge IoT project with a highly skilled team.
A clear and fast recruitment process.
