About the role

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 intent we have over 15+ years of experience in helping to conceptualize, design, and build apps for IoT and connected devices. We are a software house from Poland that acts as a specialized think partner for products at the intersection of physical and digital - from net-new to products looking to enter a competitive and established niche. Some of our clients include Oura, BOSE, and McIntosh audio systems. This is an opportunity to work on a high-impact project where your deep BLE knowledge will be critical.



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) 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 (5-8k 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.
