Responsibilities

The Opportunity

We're hiring a Senior RF Embedded Systems Engineer to lead the design, development, and prototyping of our next-generation IoT tracking devices. You'll be the first technical hire on the hardware engineering side-owning circuit design, firmware, integration, and RF performance in a tight feedback loop with product and manufacturing teams.

This is a high-impact, hands-on role where you'll take a concept from napkin sketch to functional prototype, validate performance, and work closely with our GM of Hardware and contract manufacturers to scale it into production.

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.

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.
