Guidance Nav & Control Engineer - Navigation Sys/Inertial Sensor (Senior)

We are seeking a Senior Guidance Navigation and Controls Engineer to join our team in El Segundo, California. As a Senior level contributor, you will provide inputs that significantly impact the GNC and adjacent subsystems towards mission success, influence others, and make process and tool improvements.

Responsibilities:

• Design, implement, and verify guidance, navigation, and control algorithms for spacecraft, primarily satellites.
• Develop or modify, and run, 6-DOF dynamic simulations with flight software (FSW) or prototype FSW code in MATLAB and C++.
• Support program milestones on time, showcasing GNC analysis and FSW meets requirements such as at critical design reviews, flight qualification testing, etc.
• Develop system architecture solutions and trade studies such as actuator sizing or sensor evaluation for navigation on new programs.
• Support integration and testing of GNC hardware, including hardware in the loop testing and characterize real hardware performance when needed.
• Support flight launch and initialization by developing concept of operations (CONOPS), mission tools, calibrations, and actual on console mission support.
• Collaborates with cross-functional teams (systems engineering, avionics, test, and business development) and communicate technical tradeoffs to stakeholders.
• Independently identify inefficiencies, propose solutions, and implement reusable tools and automations.
• Leads engineering project teams, mentor engineers and advance job practices and techniques as it relates to GN&C.

Requirements:

• Bachelor of Science degree from an accredited course of study in engineering, engineering technology (includes manufacturing engineering technology), chemistry, physics, mathematics, data science, or computer science.
• 5+ years of experience in spacecraft GNC, ACS, flight dynamics, validation, and/or systems engineering.
• 1+ years of experience in verification and validation of complex systems.
• Education or experience in one or more of the following; C, C++, Python, MATLAB, Java, Linux.

Preferred Qualifications:

• 9+ years’ related work experience or an equivalent combination of relevant education and experience (e.g. Master’s and 7+ years).
• Active Top Secret SCI Clearance.
• Prior responsibility on spacecraft programs with demonstrable end-to-end GNC ownership, and experience across the entire lifecycle of a program.
• Solid knowledge of satellite GNC topics such as sensors and navigation, estimation, actuators, control theory, steering laws, orbital mechanics, GNC flight software, mission CONOPS.
• Excellent technical communication skills and proven ability to work well with and lead teams.
• Experience with model-based verification frameworks, automated test benches, and continuous integration for GNC models and flight software.
• Trade study reports (propellant budget, pointing budgets, momentum budgets, sensor selection) with recommended solutions and rationale.
• Mission operations inputs: flight software interfaces, on-orbit commissioning plans, anomaly response strategies.
• Hands-on experience with hardware-in-the-loop (HIL), lab integration, spacecraft testbeds, and flight-test or mission operations support.
• Track record of high performance and efficiency, for example, meeting schedule pressure, process improvements, implementing new tools or AI workflows, delivering on high visibility, high quality work at cost and schedule.
• Excellent communication skills and experience mentoring junior engineers, leading teams, and coordinating with other teams and stakeholders.
