Join General Atomics as a Guidance Navigation and Control Engineer to design and develop advanced guidance, navigation and control systems for precision munitions and space vehicles. This full‑time position is based in Longmont, CO and collaborates with teams across the U.S.

General Atomics, an industry leader in high‑technology systems, offers this opportunity in our Aerospace Systems Engineering Directorate. Your work will involve algorithm design, subsystem development, simulation modeling, and detailed analyses for weapon and space system projects, providing technical expertise for precision munition and space vehicle guidance, navigation and control.

• Develop guidance, navigation and/or control algorithms and implement them in six‑degree‑of‑freedom flight simulations written in C/C++ and FORTRAN.
• Support development of precision munitions such as guided missiles, gun‑launched projectiles, and hypersonic weapon systems.
• Support development of attitude determination and control systems for spacecraft.
• Analyze simulation, ground test, and flight test data to validate models and improve algorithms.
• Collaborate with senior GNC engineers and cross‑functional teams on complex development efforts.
• Document simulation development using GA‑EMS guidelines and industry best practices.
• Prepare briefing materials for design reviews.
• Conduct peer reviews of GNC algorithms, simulation models, and software modules.
• Resolve delays in simulation and analysis tasks through effective communication with program leadership.
• Collaborate daily with GA and customer engineering and program management teams.
• Produce GNC‑related data deliverables.
• Assist in concept development, proposal writing, and technical white papers.
• Complete any additional duties as required.
• Travel less than 20 %.
• Work a 9x80 schedule with every other Friday off.

We recognize and appreciate the value of diverse backgrounds and welcome all qualified individuals to apply.

• Bachelor’s, master’s, or PhD in mechanical, electrical, or aerospace engineering with guidance, navigation, or control experience; required years: 6+ for bachelor’s, 4+ for master’s, 2+ for PhD.
• Deep understanding of GNC concepts and principles.
• Strong experience with control, navigation and guidance algorithms for atmospheric flight and orbit.
• Prior experience developing high‑fidelity flight simulations for missiles, projectiles, hypersonic vehicles, or satellites.
• Proficiency in FORTRAN, C/C++, Matlab, and Python.
• Ability to develop and communicate new concepts, coordinate work phases, and solve complex problems.
• Excellent communication, documentation, and presentation skills; independent and team oriented.
• Active DoD Secret clearance; ability to upgrade to Top Secret.
• Willingness to work extended hours to meet deadlines and travel as required.
• Strong initiative – collaborate with multidisciplinary teams to develop new weapon systems.
• Excellent communication – document and present technical briefings to stakeholders.
• Rapid problem solving – identify issues, analyze data, and devise innovative solutions.
• Schedule performance – influence and collaborate across the organization to meet contract schedules.

• Experience developing GN&C solutions for gun‑launched guided projectiles in severe environments.
• Experience with Software‑in‑the‑Loop (SWIL) and Hardware‑in‑the‑Loop (HWIL) simulation and testing.
• Experience implementing and testing autonomy, collaborative engagement, AI, and machine learning algorithms.
