Job 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

Develop guidance law algorithms and verify their performance with high-fidelity simulation and data analysis

Create trajectory-generation tools that produce feasible, optimal paths while accommodating all vehicle hardware and dynamic limitations

Design closed-loop control laws to enable vehicle state manipulation that achieves the commanded mission; generate high fidelity simulations to verify performance

Evaluate system performance in complex scenarios and environments and verify system and subsystem level requirements

Perform critical studies, analyses, and test activities that support ground and flight test efforts including Hardware-In-The-Loop (HWIL) activities

Opportunities will exist to join small teams of engineers and algorithm developers on a variety of different programs that are in various stages of product development.

Support program reviews and technical interchange meetings with internal leadership and/or external customers.
