  • Apply RTOS and operating system concepts, including process threading, synchronization, and communication mechanisms
  • Collaborate with engineering teams on:
    • Code optimization and efficiency improvements
    • Research and evaluation of next-generation technologies
    • SDK integration and analysis
  • Partner with QA teams to:

  • Basic understanding of embedded systems and RTOS concepts
  • Familiarity with hardware communication protocols such as SPI, UART, and TCP/IP is preferred
