About the RoleSierra Space is seeking a Guidance, Navigation & Controls Engineer I to support the development and analysis of spacecraft systems. This entry-level role is ideal for talented individuals passionate about applying engineering principles to create innovative solutions in guidance, navigation, and control (GNC). The selected candidate will work on tasks involving control systems, orbital mechanics, and simulations under the guidance of senior engineers and technical leads. This position offers the opportunity to grow technical expertise in GNC systems while contributing to cutting-edge aerospace projects.
In this role, you will assist in the design, analysis, and implementation of GNC algorithms, including classical control design and Kalman filtering. You will support GNC mode transition analysis and performance evaluations for spacecraft systems, as well as perform Monte Carlo simulations to quantify system performance and ensure compliance with requirements. Additionally, you will develop MATLAB scripts and models to analyze GNC subsystems and integrate simulations with SIMULINK and STK tools. You will analyze and interpret data from GNC sensors such as IMUs and GPS, collaborate with team members to integrate GNC flight software (FSW), and conduct hardware-in-the-loop (HITL) simulations. Furthermore, you will document results, provide technical reports, and communicate findings to the team and stakeholders, while estimating workloads and prioritizing day-to-day tasking under the direction of technical leads.
About YouOur 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.
We’re looking for team members who align with our values, mission and goals – while also meeting the minimum qualifications below. The preferred qualifications are a bonus, not a requirement.
