Full Job Description
# **Sierra Space Careers:** At Sierra Space, we build the missions and systems that keep our world secure in the domain above Earth. Sierra Space team members share a spirit of innovation and collaboration and a belief that we can deliver on the boldest missions in space today. Together with our customers, we aim to safeguard our nation, sustain human presence in space, and secure the freedom of operations in low Earth orbit and beyond. Our success is measured by the trust of those who rely on what we build and deliver, and our technologies keep the United States and its allies mission-ready throughout space. We are mission-driven, and together, we are an extraordinary team. # **About the Role** Sierra Space is seeking a Guidance, Navigation & Controls Engineer II to contribute to the design, analysis, and implementation of advanced GNC systems for spacecraft applications. This mid-level role is ideal for engineers with foundational experience in dynamic modeling, algorithm design, and simulation analysis. The selected candidate will work independently on complex tasks while collaborating with cross-functional teams to ensure system performance and compliance with requirements. This position offers the opportunity to expand technical expertise and take ownership of key GNC subsystems. In this role, you will develop, implement, and evaluate GNC algorithms, focusing on one or more areas of guidance, navigation, control, and Fault Detection, Isolation, and Recovery (FDIR). You will program and optimize simulations using SIMULINK and STK, while modeling and analyzing GNC sensors and actuators such as IMUs, GPS, star trackers, Reaction Control Systems (RCS), Reaction Wheels, Magnetic Torquer Bars, Control Moment Gyros, and LIDAR. Additionally, you will run and modify Monte Carlo simulations, performing in-depth analysis to identify issues and optimize system performance. You will analyze and implement autonomous GNC mode transitions to ensure system reliability and robus
