Overview

We are looking for an RFID Solutions & Mesh Firmware Engineer to join our hardware team and bridge product development with customer deployment. This hybrid role combines embedded firmware engineering with hands-on RFID solution delivery, supporting Department of Defense (DoD) logistics modernization efforts.

Approximately half of your time will focus on developing firmware for LMI's Mesh hardware platform, including active asset tags, gateways, sensors, and secure wireless devices. The other half will be spent working directly with customers to design, deploy, and optimize passive RFID solutions in operational environments. You'll conduct site surveys, configure RFID hardware, lead demonstrations and pilot events, troubleshoot field issues, and translate operational feedback into product improvements.

This is a primarily remote role with approximately 25–35% CONUS travel to government and customer facilities.

LMI is a new breed of digital solutions provider dedicated to accelerating government impact with innovation and speed. Investing in technology and prototypes ahead of need, LMI brings commercial-grade platforms and mission-ready AI to federal agencies at commercial speed.

Leveraging our mission-ready technology and solutions, proven expertise in federal deployment, and strategic relationships, we enhance outcomes for the government efficiently and effectively. With a focus on agility and collaboration, LMI serves the defense, space, healthcare, and energy sectors, helping agencies navigate complexity and outpace change. Headquartered in Tysons, Virginia, LMI is committed to delivering impactful results that strengthen missions and drive lasting value
