  • Develop and verify software builds (including test scripts) required for hardware verification activities, including reliability, regulatory, and wireless certification tests.
  • Provide time estimates for the completion of assignments to meet project deadlines


  • Experience using C/C++ in an embedded environment writing low-level drivers and optimizing code for space or size depending on requirements
  • Experience with object-oriented design and developing embedded firmware with UML/OOAD and TDD
  • Experience working with embedded operating systems and ARM-based processors
  • Experience with standard communication protocols (I2C, UART, SPI, USB), analog-to-digital converters, timers, clocks, and interrupts
  • Ability to read and interpret schematics and component datasheets

  • Self-starter and can work independently or collaboratively with a team
    • Degree in Computer Engineering/Computer Science
    • Minimum 5-years of related experience

    Bonus points for:

    • Experience in other programming languages such as Python, Java, or MATLAB
