Job summary

Rising Tide Technology Group, Inc. in Huntsville, Alabama, seeks a Senior UAS Engineer to lead development, integration, and sustainment of uncrewed aircraft platforms from firmware to flight stack, ensuring robust performance in demanding environments.

You will work in C/C++ across PX4, ArduPilot, and Betaflight, drive hardware integration, flight-control tuning, and flight-log analysis, and provide technical leadership to junior engineers.

Qualifications

• Bachelor's degree with a minimum of 7 years of relevant engineering experience, including direct UAS development and integration.
• Advanced experience with PX4, ArduPilot, and Betaflight, including firmware development, source-code modification, compilation, debugging, flashing, and validation on physical hardware.
• Strong proficiency in C/C++ programming, embedded systems, MAVLink protocols, and ground-control software, including QGroundControl, Mission Planner, and Betaflight Configurator.
• Extensive hands-on experience with UAS hardware integration, flight-controller tuning, flight-log analysis, and complex hardware/software troubleshooting, with demonstrated ability to independently lead technical engineering initiatives.
• Strong analytical, problem-solving, communication, and technical leadership skills, with proficiency in Git and version-controlled development workflows; ability to work independently and collaboratively in a fast-paced environment. U.S. citizenship required.

Responsibilities

• Lead the development, modification, building, debugging, and deployment of flight-controller and autopilot firmware across PX4, ArduPilot, and Betaflight platforms, working directly within C/C++ source code.
• Design and implement enhancements to flight modes, control algorithms, parameters, mixers, failsafes, and embedded flight-control logic.
• Lead hardware and software integration efforts involving flight controllers, ESCs, sensors, radios, telemetry systems, companion computers, and mission-specific payloads.
• Oversee UAS performance optimization, including advanced PID/rate tuning, filtering, vibration analysis, and flight-log evaluation.
• Develop and execute structured bench, integration, and flight-testing procedures to validate system performance, reliability, and operational readiness.
• Lead complex technical investigations, analyze flight logs (Blackbox, ULog, DataFlash), identify root causes, and implement corrective engineering solutions.
• Develop and maintain Python-based scripting, automation tools, and reproducible firmware build processes using Git and version-control best practices.
• Serve as a technical subject matter expert, providing engineering guidance, mentorship, and recommendations to junior engineers and cross-functional teams.
• Collaborate with operations, pilots/RPICs, customers, and suppliers to translate mission requirements into engineering solutions while identifying technical risks and developing mitigation strategies.
• Establish engineering best practices and maintain technical documentation, firmware baselines, test results, and engineering reports; prepare and deliver technical briefings and recommendations to stakeholders.
