Location: United States
Workplace: Onsite
Employment Type: Full time
Job Function: Hardware, Embedded & Systems Engineering
Seniority: Mid level

Key Responsibilities

  • •Write high-performance bare-metal C/C++ firmware for resource-constrained microcontrollers controlling the RF front-end of Mach’s radar RF seekers.
  • •Bring up low-level firmware from scratch, including peripheral/drivers (I2C, SPI, CAN, GPIO) to configure RF/microwave ICs and interface with other subsystems.
  • •Verify RF front-end functionality and performance by devising lab tests using RF/microwave test equipment and software validation methods.
  • •Develop and implement RF calibration techniques by analyzing amplitude, phase, and performance metrics to optimize RF front-end behavior.
  • •Own firmware quality, reliability, and performance by identifying, documenting, tracking, and fixing issues; author specifications and testing procedures to support manufacturing scalability.
