Job summary

Sierra Space seeks a Guidance, Navigation & Controls Engineer I to support development and analysis of spacecraft systems. This entry-level role involves design, analysis, and implementation of GNC algorithms, with exposure to simulations, Kalman filtering, and HITL testing under senior guidance.

You will develop MATLAB models, integrate with SIMULINK and STK, analyze IMU/GPS data, and contribute to mode transitions and performance evaluations for space missions. This role requires a U.S.

Qualifications

• Bachelor's degree in aerospace engineering, mechanical engineering, electrical engineering, or a related technical field (or equivalent work experience in lieu of degree).
• 0-2 years of relevant engineering experience (including academic projects, internships, or research).
• Foundational knowledge of statics, dynamics, control systems, and orbital mechanics.
• Proficiency in MATLAB programming and familiarity with SIMULINK, STK, and version control tools such as GIT/SVN.
• Basic understanding of GNC sensors like IMUs and GPS and their operating principles.
• The ability to obtain and maintain a U.S. Security Clearance is required.

Responsibilities

• Assist in the design, analysis, and implementation of GNC algorithms, including classical control design and Kalman filtering.
• Support GNC mode transition analysis and performance evaluations for spacecraft systems.
• Perform Monte Carlo simulations to quantify system performance and ensure compliance with requirements.
• Develop MATLAB scripts and models to analyze GNC subsystems and integrate simulations with SIMULINK and STK tools.
• Analyze data from GNC sensors (IMUs, GPS) and help integrate GNC flight software (FSW).
• Collaborate with team members to conduct HITL simulations and document results for stakeholders.
