Job description
ABOUT FIREFLY AEROSPACE
Firefly Aerospace is a space and defense technology company on a mission to reliably and repeatedly launch, land, and operate space systems from Earth to the Moon and beyond. As the partner of choice for critical space missions, Firefly is the first commercial company to launch a satellite to orbit with 24-hour notice and the first company to achieve a successful Moon landing. 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 Flight Dynamics Engineer specializing in trajectory and maneuver design at Firefly, you will design and optimize spacecraft trajectories and maneuver sequences for operational missions spanning LEO and cislunar space. In this role, you will develop targeting algorithms, create error budgets, and serve as a flight dynamics operator while collaborating with cross-functional teams to translate mission designs into executable operations. This position combines advanced mission design with hands-on operational support while mentoring junior engineers in a fast-paced, mission-critical environment.
RESPONSIBILITIES
Required
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.
To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

- Formulate and analyze contingency maneuver plans and abort scenarios for off-nominal conditions
- Interface with cross-discipline teams to translate maneuver plans into executable command sequences and operational procedures
- Serve as a flight dynamics operator for spacecraft missions and perform maneuver reconstruction to improve spacecraft models
- Perform verification and validation of flight dynamics models and software using analytical solutions, benchmarks, flight data, and unit tests
- Author technical documentation and analysis reports that communicate flight dynamics concepts and results to diverse audiences
Required
- Bachelor's degree in aerospace engineering, physics, mathematics, or related field
- 5-8 years of experience in spacecraft flight dynamics with significant depth in mission design or maneuver planning
- Experience supporting operational spacecraft missions through multiple mission phases
- Advanced understanding of orbital mechanics theory and applications
- Understanding of spacecraft attitude control and its impact on maneuver execution accuracy
- Strong understanding of targeting and optimization methods
- Knowledge of estimation theory and uncertainty modeling
