Job summary

DMR Technologies in Lafayette, LA, is developing next-generation drone technology. The flight controllers already fly production missions with multi-IMU redundancy, dual GPS+RTK, and dual-antenna heading fusion. We seek a firmware engineer to own the system, push it forward, and help scale.

The role covers RTK/4G feature work, sensor drivers for IMU/GNSS/compass/barometer, SDK maintenance, and calibration tooling, with a focus on reliability and mass production readiness.

Qualifications

• Bachelor's degree or above in a relevant field.
• 5+ years embedded flight control firmware experience.
• Experience taking a drone controller from development to mass production.
• Knowledge of multi-sensor fusion and RTOS/bare-metal environments.

Responsibilities

• Own the flight control firmware and evolve a production codebase for multi-IMU redundancy, dual GPS+RTK, and heading fusion.
• Lead feature development and stability tuning for RTK and 4G modules.
• Develop and maintain sensor drivers: IMU, GNSS, magnetic compass, barometer, Hall/ultrasonic flow meters, and radar.
• Implement production-line calibration methods and support test fixtures.
• Maintain the flight control protocol SDK; coordinate integration with application and cloud teams.
• Refine flight modes and safety strategies; contribute early research into RTK base stations and centrifugal nozzles.
• Close the loop on mass-production issues and ensure firmware consistency across batches.

Flight Control Firmware Engineer Lafayette, LA

• Full-Time
• Built on the Bayou - Bringing the Future of Flight to Life
• The description below is a best-case candidate. This specific role could potentially be a part-time internship for someone in the 3rd / 4th year of a computer science-related field.

DMR is building next-generation drone technology right here in Lafayette, LA. Our flight controllers are flying production missions today - multi-IMU redundancy, dual GPS+RTK, dual-antenna heading with magnetometer fusion, and layered safety strategies. We need a firmware engineer ready to own this system, push it forward, and help us scale.

What You'll Do

• Own the flight control firmware - analyze, document, and evolve a mature production codebase covering multi-IMU redundancy, dual GPS+RTK, and dual-antenna heading fusion.
• Lead feature development and stability tuning for RTK and 4G modules.
• Develop and maintain sensor drivers: IMU, GNSS, magnetic compass, barometer, Hall/ultrasonic flow meters, and radar.
• Implement production-line calibration methods and support test fixtures.
• Maintain the flight control protocol SDK; coordinate integration with application and cloud teams.
• Refine flight modes and safety strategies; contribute early research into RTK base stations and centrifugal nozzles.
• Close the loop on mass-production issues and ensure firmware consistency across batches.

What You Bring

• Bachelor's degree or above in Automation, Electronics, Aerospace, Computer Science, or related field.
• 5+ years of embedded flight control firmware experience, including at least one drone controller taken from development through mass production.
• Strong STM32 (H7 preferred) skills - both bare-metal and RTOS environments.
• Solid knowledge of IMU/GNSS-RTK/compass drivers and multi-sensor fusion (Kalman/ESKF), attitude estimation, and control algorithms.
• Familiarity with CAN, RS-485, serial, PWM, ADC, and other embedded bus interfaces.
• Self-directed - you can troubleshoot independently and drive work to completion.

Bonus Points

• Agricultural or crop-protection drone experience: spraying, spreading, seeding, swath-width route planning, or resume-spraying.
• RTK high-precision positioning, dual-antenna heading, or 4G base station integration experience.

DMR is headquartered in Lafayette, LA - the heart of Cajun Country. We move fast, build real products, and take pride in doing it here. If you're ready to own the firmware on drones that are actually flying, we want to hear from you.
