With a workforce of approximately 350 employees, we operate with startup agility and ambition.

Our vision is to redefine the future of warfare through cutting-edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security.

The Role

The RF Firmware Engineer will play a key role in developing advanced RF sensing capabilities for Mach’s autonomous defense platforms. Working on the DART team, you will focus directly on next-generation counter-UAV radar systems and RF seekers. You will be responsible for designing, implementing, verifying and optimizing the embedded firmware that controls the RF front-end of Mach’s RF seeker across the full development lifecycle - bare-metal board bring-up to final deployment.

This role involves close collaboration with cross-functional teams that include antenna and RF hardware engineers to ensure the entire radar RF front-end system meets the mission-critical requirements. Success in this role requires strong technical execution, adaptability, and a hands-on approach in a fast-paced, iterative environment.

Key Responsibilities

Mission : Build next generation counter-UAV defense systems that will be used to defend human lives, critical infrastructure, and high value assets for the United States and its allies.

Firmware development : Write high-performance, bare-metal C/C++ firmware for resource constrained microcontrollers powering the RF front-end boards in Mach’s radar products.

Hardware co-design : Work with hardware engineers on component selection, board bring-up, and optimal hardware-software trade-offs (power, cost, form factor).

Firmware bring-up : Bring-up low level C/C++ bare-meta code from scratch, including peripherals/drivers (I2C, SPI, CAN, GPIO) to configure RF/microwave ICs (such as DDS, PPL, LNA, PA, filters, switches, etc) and interface to other subsystems.

RF performance verification: Devise lab tests using RF/microwave test equipment to verify the functionality of the firmware and performance of the RF front-end boards.

RF calibration : Analyze amplitude, phase, and performance metrics to develop calibration techniques and implement calibration techniques in firmware to optimize the performance of the RF front-end boards.

Automation/Scripting : Write scripts (Python) to automate factory RF/microwave calibration processes to speed up calibration and ensure a high calibration accuracy.

Testing and reliability : Own firmware quality, reliability and performance by proactiv
