Responsibilities:

WHAT YOU’LL DO

• Design and prototype embedded systems for low-power, RF-connected devices (LoRa, LTE-M, BLE, GNSS, etc.).
• Develop and debug firmware on microcontrollers using C/C++
• Design and test RF circuits, antennas, and matching networks for reliable comms in field environments.
• Build and validate custom PCBs (schematics, layout guidance, component selection).
• Conduct bench-level testing, including signal analysis, power profiling, and RF range validation.
• Implement FIPS 140-3 compliant encryption and secure boot mechanisms to meet DoD cybersecurity requirements.
• Create test plans and documentation for transitioning prototypes to manufacturing.
• Collaborate closely with contract manufacturers and hardware leads to support DFM, DFT, and QA workflows.
• Support FCC, TAA, or MIL-STD pre-certification efforts as needed.
  Qualifications:

WHY THIS ROLE MATTERS

You won’t just be coding firmware or simulating RF—you’ll be building the foundation of a new hardware product line that’s headed straight into real-world military use. You’ll see your designs go from bench to battlefield.
