Description:Who We Are
Lockheed Martin is a global security and aerospace company that employs approximately 114,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration, and sustainment of advanced technology systems, products, and services. Lockheed Martin Missiles and Fire Control (MFC) is one of four Lockheed Martin business areas.
By bringing together people that use their passion for purposeful innovation, at Lockheed Martin we keep people safe and solve the world's most complex challenges. Our people are some of the greatest minds in the industry and truly make Lockheed Martin a great place to work. With our employees as our priority, we provide diverse career opportunities designed to propel development and boost agility.
Our flexible schedules, competitive pay, and comprehensive benefits enable our employees to live a healthy, fulfilling life at and outside of work. At Lockheed Martin, we place an emphasis on empowering our employees by fostering innovation, integrity, and exemplifying the epitome of corporate responsibility. Your Mission is Ours.
We are seeking an experienced Guidance and Control (GNC) Engineer who will join a highly skilled team of systems engineering technologists and algorithm developers supporting missile system and fire control system design, development, integration, and test.
What You Will Be Doing
A GNC Engineer is responsible for the design, analysis, integration, testing, and validation of the algorithms and hardware that enable a vehicle—whether a missile, unmanned aircraft, or manned spacecraft—to determine where it is, where it’s going, and how to get there safely and accurately. The role bridges multidisciplinary domains, combining control theory, aerospace dynamics, hardware modeling, simulation, and system‑level architecture.
The GNC Engineer ensures that an air vehicle knows its state, decides on the optimal path, and executes that path reliably through robust guidance laws, precise navigation filters, sophisticated flight‑path planning, and stable autopilot/control systems—all validated through rigorous simulation and flight testing. This is achieved through some combination of the following tasks:
Basic Qualifications:
Demonstrated responsibility for the full life-cycle of GNC algorithms (concept, requirements generation, design, implementation, verification, and flight test)
Demonstrated expertise in relevant mathematical concepts like linear algebra, dynamics, coordinate frame transformations, and fundamental control theory (PI filters, Laplace transform, Fourier analysis, state-space modeling, etc.)
Demonstrated expertise in guidance law or autopilot/flight controls algorithm development, test, and verification.
Demonstrated experience with SW development environments like Git using programming languages such as MATLAB, Python, C++, FORTRAN, or Ada.
Demonstrated ability to lead technical teams to achieve specific work package objectives.
Excellent written communication skills to include generation and presentation of verification plans, analysis reports, algorithm description documentation, other technical documents.
Effective oral presentation skills for design reviews and briefings to customers, partners, and senior leadership.
Desired Skills:
Security Clearance Statement: This position requires a government security clearance, you must be a US Citizen for consideration.
Clearance Level: Secret with Investigation or CV date within 5 years
Other Important Information You Should Know
