Flight Control Firmware Engineer

DMR TECHNOLOGIES INC•Lafayette, LA

8d•$14 - $60•Onsite

About The Position

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. This specific role could potentially be a part-time insurance for someone in the 3rd / 4th year of a computer science-related field.

Requirements

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.

Nice To Haves

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.

Responsibilities

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.
