  • Utilize specialized Bluetooth test tools and protocol analyzers (e.g., Ellisys, Teledyne LeCroy) to capture, decode, and analyze Bluetooth traffic.
  • Conduct performance testing to assess Bluetooth range, data throughput, connection stability, and battery consumption, particularly for Bluetooth Low Energy (BLE) devices.
  • Test Bluetooth security features, including pairing protocols, encryption, and authentication, to identify vulnerabilities and ensure data protection.

Salary: $120,000 - $180,000 per year

Required Skills:

  • At least 5+ years of experience in software testing/development, with a focus on Bluetooth technology and test automation using Python/Embedded C.
  • In-depth knowledge of Bluetooth technologies, including Bluetooth Classic, Bluetooth Low Energy (BLE), Bluetooth mesh, and the Bluetooth protocol stack.
  • Strong understanding of Bluetooth profiles such as A2DP, HFP, HID, GATT, PAN, LE Audio, and their respective functionalities and use cases.
  • Expertise in using Bluetooth testing tools and protocol analyzers (e.g., Ellisys, Teledyne LeCroy, Frontline).
  • Experience with Bluetooth specification documentation (e.g., Bluetooth SIG), and familiarity with Bluetooth standards (e.g., Bluetooth 5.x, BLE)
  • Strong analytical and troubleshooting skills, particularly in complex Bluetooth connectivity and performance issues.
  • Excellent communication skills to effectively collaborate with cross-functional teams, document test results, and present findings clearly to stakeholders.

Preferred Qualifications:

  • Bachelor's or Master's degree in Computer Science, Electrical Engineering, Telecommunications, or a related field.
  • Experience with the Bluetooth Qualification process or Bluetooth certification is a plus.
