We’re looking for an experienced Bluetooth Low Energy (BLE) Expert to join our team as a freelancer immediately. If you have a strong commercial background in BLE, IoT, and mobile development (iOS or Android), 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.

Who we’re looking for:

• Strong mobile development skills – expertise in either iOS (Swift, Core Bluetooth) or Android (Kotlin, BLE APIs).
• 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, or JUnit, Mockito for Android).
• 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).
• Knowledge of Google Play/Android Auto or Apple MFi programs.

What we offer:

• Fully remote and flexible work.
• 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.

Recruitment process:

1. Quick screening call with HR (45 min).
2. Technical interview with live coding (max. 90 min).
3. Final feedback within a couple of days.
