About the role

  • Lead the architecture, design, and development of Bluetooth Classic, BLE, LTE-M, NB-IoT, and 5G features for embedded platforms and smartphones.
  • Serve as a subject matter expert and mentor, guiding team members on best practices for wireless development, debugging protocols, and modem firmware updates (FOTA).
  • Collaborate with product, hardware, and mobile teams to define end-to-end connectivity requirements and solutions, including SIM/eSIM management and device provisioning.
  • Debug, optimize, and validate wireless protocols and firmware across multi-core embedded systems and mobile OS environments, with a focus on power consumption and data throughput.
  • Design and implement automated testing frameworks for both Bluetooth and LTE certification (e.g., PTCRB, GCF) and interoperability testing.
  • Stay ahead of industry trends and emerging technologies, such as Bluetooth SIG standards, 3GPP specifications, low-power wide-area networks (LPWAN), and cellular V2X, to ensure Motive products remain cutting-edge.
