Description About Lockheed Martin Space: Space is a critical domain, connecting our technologies, our security, and our humanity. While others view space as a destination, we see it as a realm of possibilities, where we can innovate, invest, inspire, and integrate our capabilities to transform the future. At Lockheed Martin Space, we aim to harness the full potential of space to cultivate innovation, reduce costs, and push the boundaries of what technology can achieve. We’re creating future‑ready solutions, focusing on resiliency and urgency through our 21st Century Security vision. We’re erasing boundaries and forming partnerships across industries and around the world. We’re advancing spacecraft and the workforce to fuel the next generation, and we’re reimagining how space can connect us, ensuring security and prosperity. About the Role We are seeking an experienced Guidance, Navigation, and Control (GNC) Engineer, Navigation Technical Specialist who will perform technical execution scope associated with navigational system design, algorithm development, software integration, sensor system modeling & analysis, performance analysis, hardware‑integrated testing, and weapons system verification within the Theater Strike Weapon Systems (TSWS) and Strategic Missile Defense (SMD) portfolios. Anchored by the Conventional Prompt Strike (CPS) program, the portfolio is undergoing rapid growth associated with multiple product lifecycle phases within CPS and several peer development program efforts. Key Responsibilities Work on advanced missile design, integration, testing, and analysis within a hypersonic weapon system program. Leverage past experience in weapon system and missile system/subsystem development and analysis to shape current and future program execution. Collaborate with program managers, systems and software engineering or engineering leaders to deliver component(s)/subsystem(s), designs, and analysis to programs. Provide programmatic direction to engineering staff and team(s), collaborate on execution, analysis, design/peer reviews. Apply proficiency in C++ and MATLAB to develop, verify, validate, and perform analysis; review analysis artifacts of others; assess data products and deliver technical summary briefings. Communicate technical results effectively and work collaboratively across teams, work groups, review boards, and technical execution teams. Support Agile execution of programs and projects through proposals, planning/backlog development, product ownership, and staffing coordination. Develop and review data packages, analysis, and presentations for working groups and review boards. Coordinate internal efforts and external elements (partner, subcontractor, peer prime) to develop, verify, and validate navigational sensors and algorithms to achieve weapon system performance. Evaluate system performance in complex scenarios and environments and verify system and subsystem level requirements across simulation, hardware testing, and full system test execution. Support program reviews and technical interchange meetings with internal leadership and/or external customers. Basic Qualifications B.S. or M.S. in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, or related field. Demonstrated experience working on defense, aerospace, and/or space navigation programs. Fundamentals of inertial navigation systems (INS) and/or GNSS (multi‑constellation, RTK, SBAS). Familiarity with navigation performance metrics (accuracy, availability, continuity, or integrity). Understanding of Position, Navigation, and Timing (PNT) concepts, error budgeting, and integrity monitoring. Proficiency in C/C++, MATLAB/Simulink, and/or Python for algorithm development and data analysis. Knowledge of software methods or standards including safety‑critical items and/or version control systems (Git, Gitlab, Artifact repos). Ability to develop and maintain navigation error budgets, covariance analysis, and/or perform statistical analyses. Proficiency with high‑fidelity simulation tools. Security Clearance / Work Authorization This position requires the selected employee to be a U.S. Citizen. Secret clearance is required to start employment. Selected candidates will be required to obtain, and maintain, a government‑issued Secret clearance for long‑term employment on this program. Desired Skills Professional experience with 9+ years applicable GNC focus associated with Weapon System product lifecycle. Experience in Inertial Navigation Systems (INS) & GNSS systems, including INS error modeling, GNSS signal structures, multi‑constellation processing, platform transfer alignment, and integration algorithms (e.g., Kalman filters, particle filters). Experience in Advanced PNT Concepts, such as precise orbit determination, time transfer, sensor fusion (INS‑GNSS ADS), integrity monitoring, differential GNSS, and emerging technologies and augmented autonomous navigation. Demonstrated navigation performance metric efforts; ability to define, compute, and validate metrics such as accuracy, integrity, continuity, availability, and reliability. Experience defining technical requirements, reviewing subcontractor proposals, and validating deliverables. Familiarity with cyber‑resilient navigation concepts, anti‑spoofing/anti‑jamming techniques, and secure PNT architectures. Designing, configuring, and executing HWIL test rigs for navigation software validation on flight processors including proficiency in real‑time operating systems (RTOS) for time‑deterministic navigation processing. Benefits Medical, Dental, Vision, Life Insurance, Short‑Term Disability, Long‑Term Disability, 401(k) match, Flexible Spending Accounts, EAP, Education Assistance, Parental Leave, Paid time off, and Holidays. This position is incentive plan eligible. Eligibility Lockheed Martin is an equal opportunity employer. Qualified candidates will be considered without regard to legally protected characteristics.
