About the role
- Senior GNC Engineer designing and implementing advanced control systems for operational launch vehicles at Firefly Aerospace. Collaborating with multidisciplinary teams in a fast-paced operational environment.
Responsibilities
- Design, analyze, and tune launch vehicle attitude control software to ensure stable flight from launch to orbit
- Implement control techniques for mission-critical flight phases using thrust vector control actuators, reaction control thrusters, and aerodynamic surfaces
- Develop control systems accounting for complex launch vehicle dynamics including aerodynamic effects, structural flex modes, propellant slosh, and control structure interaction
- Establish technical standards and validation methodologies for control system design, software development, and hardware-in-the-loop testing
- Conduct stability analysis, sensitivity studies, and performance optimization for control systems under nominal and off-nominal flight conditions
- Support hardware-in-the-loop test campaigns for integrated GNC systems including control algorithm validation, flight software verification, and system-level performance testing
- Drive resolution of complex GNC challenges requiring deep technical expertise and rapid problem-solving
- Provide technical direction on system architecture and serve as subject matter expert for launch vehicle control
- Mentor junior engineers in control theory and flight software development
- Author technical documentation and analysis reports that communicate GNC concepts and results to diverse audiences
- Interface with cross-discipline teams to integrate control software with vehicle hardware
- Serve as a GNC console operator for launch operations and perform post-flight analysis to improve vehicle models
- Champion continuous improvement initiatives for GNC processes, tools, and operational efficiency
Requirements
- Bachelor's degree in aerospace engineering, mechanical engineering, electrical engineering, computer science, or related field
- 5-10 years of experience in launch vehicle GNC systems with significant depth in attitude control system design or flight software development
- Advanced knowledge of attitude dynamics and control theory, including rotational dynamics, attitude representations, control moment generation, and stability analysis
- Strong understanding of classical control theory and frequency domain analysis techniques
- Expertise in real-time software development using C++ for flight-critical applications
- Experience developing high-fidelity actuator models and attitude control system testbeds
- Proficiency in hardware-in-the-loop testing and requirement verification for flight-critical systems
- Understanding of software development best practices including version control (Git), code documentation, and testing
- Excellent communication and presentation skills
