Careers At Firefly Aerospace
Firefly Aerospace is a space and defense technology company that enables our world to launch, land, and operate in space – anywhere, anytime. As the partner of choice for critical space missions, Firefly is the only commercial company to launch a satellite to orbit with 24-hour notice and the only company to achieve a successful Moon landing. Our launch vehicles, lunar landers, and orbital vehicles provide government and commercial customers with full mission services from low Earth orbit to the Moon and beyond. Headquartered in north Austin, Texas, Firefly is looking for passionate, hardworking innovators to join our team and help fuel our successful trajectory into space.
SUMMARY
As a Senior ADCS Engineer specializing in controls and autonomy at Firefly, you will design and implement advanced control systems and autonomous flight software for operational spacecraft. In this role, you will develop and tune attitude control software, support hardware‑in‑the‑loop testing and system integration, and provide technical leadership while collaborating with multidisciplinary teams. This position combines advanced control theory, real‑time embedded systems development, and hands‑on flight operations support while mentoring junior engineers in a fast‑paced operational environment.
RESPONSIBILITIES
Design, analyze, and tune spacecraft attitude control software to ensure accurate pointing across all mission phases
Implement control techniques for critical mission phases using reaction wheels, control moment gyros, magnetic torque rods, and thruster systems
Develop control systems accounting for complex spacecraft dynamics including structural flex modes, propellant slosh, gimbal dynamics, 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 conditions
Support hardware‑in‑the‑loop test campaigns for integrated ADCS systems including control algorithm validation, flight software verification, and system‑level performance testing
Drive resolution of complex ADCS challenges requiring deep technical expertise and rapid problem‑solving
Provide technical direction on system architecture and serve as subject matter expert for spacecraft control
Mentor junior engineers in control theory and flight software development
Author technical documentation and analysis reports that communicate ADCS concepts and results to diverse audiences
Interface with cross‑discipline teams to integrate control software with spacecraft hardware
Serve as an ADCS console operator for spacecraft operations and perform post‑mission analysis to improve spacecraft models
Champion continuous improvement initiatives for ADCS processes, tools, and operational efficiency
QUALIFICATIONS
Required
Bachelor's degree in aerospace engineering, mechanical engineering, electrical engineering, computer science, or related field
5-10 years of experience in spacecraft ADCS 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 mission‑critical applications
Experience developing high‑fidelity actuator models and attitude control system testbeds
Proficiency in hardware‑in‑the‑loop testing and requirement verification for mission‑critical systems
Understanding of software development best practices including version control (Git), code documentation, and testing
Excellent communication and presentation skills
Master's degree or PhD in aerospace engineering, mechanical engineering, electrical engineering, applied mathematics, or related field
Experience architecting and implementing control systems for operational spacecraft from development through mission operations
Expertise in advanced control techniques such as nonlinear control methods, optimal control, model predictive control, or adaptive control applied to spacecraft applications
Hands‑on experience with spacecraft actuator systems including reaction wheels, control moment gyros, magnetic torque rods, and thruster systems
Advanced knowledge of state estimation techniques including Kalman filtering, sensor fusion, and covariance analysis
Advanced knowledge of numerical methods for control law tuning, root‑solving, and parameter optimization
Experience with modern flight software frameworks and real‑time operating systems
Software engineering expertise with proficiency in development practices including version control, code review, testing, documentation, and CI/CD workflows
Proficiency in Python for scripting, data analysis, and automation
Working knowledge of spacecraft systems and mission operations
Proven ability to develop junior engineers while managing technical responsibilities
Track record of thought leadership through publications, presentations, or contributions to industry state‑of‑the‑art
Firefly offers outstanding benefits for our employees, including generous health, dental and vision plans with low plan deductibles, parental leave, educational reimbursement, short term disability, and flexible PTO options.
