About the Role

Sierra 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).

In this role, you will:

  • 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 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.
  • Document results, provide technical reports, and communicate findings to the team and stakeholders.
  • Estimate workloads and prioritize day-to-day tasking under the direction of technical leads.

Minimum 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.

Preferred Qualifications

  • Experience with academic or professional projects involving Kalman filtering and classical control design.
  • Familiarity with Monte Carlo simulation techniques and GNC mode transitions analysis.
  • Understanding of spacecraft subsystems, including power, thermal, communication, jitter, and structures.
  • Ability to integrate GNC flight software and conduct HITL simulations.
  • Strong analytical skills with the ability to interpret performance requirements and perform relevant analysis.
  • Effective communication skills and ability to work collaboratively in a team environment.
  • Participated in 2026 SS Intern Academy.

Compensation

Pay Range: $83,999.00 - $115,498.25

Your actual base compensation will be determined on a case-by-case basis and may vary based on job-related knowledge and skills, education, experience, internal equity and market competitiveness.
