Flight Control Firmware Engineer

About the role

Built on the Bayou — Bringing the Future of Flight to Life. 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.

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.

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.

Skills

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

Benefits

• Competitive salary
• Dental insurance
• Health insurance
