About the Role The Manager, Guidance, Navigation, & Control (GNC) Engineering leads the technical direction and management of GNC engineering activities supporting spacecraft, aircraft, and/or autonomous systems programs. This role balances individual technical contribution with people leadership, serving as the primary GNC lead on assigned programs while supervising engineers across design, analysis, and testing disciplines. The Manager translates functional GNC plans into actionable operational plans, procedures, and schedules; ensures technical rigor and quality across deliverables; and manages risk, budget, and schedule commitments. This individual upholds company values and standards, communicates complex GNC concepts to technical and non-technical stakeholders, and drives continuous improvement of GNC methodologies, tools, and processes across the organization.

The Manager, GNC Engineering serves as the primary GNC lead for assigned programs, holding accountability for technical rigor, product quality, and on-time delivery across all GNC deliverables. This individual makes a high level of individual technical contribution, personally leading key analyses, developing control and estimation models, and generating critical program deliverables using GNC simulation and modeling tools such as MATLAB/Simulink, as well as directing hardware-in-the-loop testing to develop and verify flight control systems. Applying comprehensive knowledge of control theory, state estimation, sensor fusion, and trajectory optimization, this person defines procedures and methodologies for GNC design, analysis, and verification, translating functional GNC plans into operational plans, task-level breakdowns (using tools such as Jira), Integrated Master Schedule (IMS) tasks, long-term plans, and Gantt charts that support program execution as well as internal and external proposals and Statements of Work (SOWs).

In addition to technical execution, this role carries managerial responsibility for supervising engineering teams across GNC design, analysis, and testing activities, balancing hands-on technical leadership with day-to-day people management. The Manager identifies, assesses, and mitigates technical, schedule, and cost risks across GNC efforts, manages program budgets, and leads organizational change by implementing new methodologies, tools, and processes to improve team effectiveness. This individual communicates complex GNC concepts clearly to diverse stakeholders including engineering teams, program management, and customers, and models and upholds company values, holding GNC teams accountable to established standards and expectations. About You Our mission is driven by an unyielding commitment to advancing space-based technology in service of our customers and safeguarding national security. We seek individuals who are passionate about innovating beyond boundaries and relentlessly pursuing solutions that protect, preserve and empower – to join us in this critical mission.
