This Firmware Engineer will focus on developing embedded firmware for radio-control (RC) systems used in hobby-grade aircraft, vehicles, and other model products. As an mid-level engineer, this role will take ownership of firmware features, contribute to system-level design decisions, and collaborate closely with hardware and product teams. This role will work on control link logic, telemetry handling, device configuration, and performance optimization for compact and lightweight electronics that power Horizon Hobby's product lines.

Key Responsibilities

• Firmware Development for RC Electronics
  - Design, implement, and maintain embedded firmware for transmitters, receivers, ESCs, sensors, and other RC components. Develop features such as signal processing, failsafe behavior, telemetry decoding, and configuration logic.
• Hardware Integration
  - Work closely with electrical engineers to bring up new boards, validate interfaces, and ensure firmware and hardware operate seamlessly together.
• RF System Support
  - Collaborate with RF engineers to integrate firmware with RF modules, optimize control - link performance, and support antenna tuning and range - testing workflows.
• CAD & Documentation Support
  - Review schematics and PCB layouts to understand hardware interfaces and constraints. Provide firmware - specific input during design reviews.
• Testing & Debugging
  - Use oscilloscopes, logic analyzers, and RF test equipment to debug issues, validate performance, and ensure reliability in real - world RC environments.
• Field & Bench Validation
  - Participate in controlled field tests with RC models to evaluate firmware behavior under realistic operating conditions.
• Continuous Improvement
