Impulse Space is seeking a Senior Navigation Engineer to own the state estimation and orbit determination systems for spacecraft and orbital transfer vehicles operating in LEO, GEO, and cislunar space. You will work closely with a fast-paced, agile engineering team to design, implement, and validate the navigation filters and sensor-fusion techniques that enable precise vehicle positioning and trajectory planning across all phases of development and operation.
Key responsibilities include:
- Design, develop, and tune navigation and estimation algorithms (EKF/UKF, batch/sequential estimators) for spacecraft and high-ΔV orbital transfer vehicles
- Perform comprehensive spacecraft navigation analyses including orbit determination, attitude determination, astrodynamic trajectories, covariance analysis, and navigation error budgets
- Develop and validate sensor models and measurement models for IMU, GNSS/GPS, star tracker, optical/relative navigation, and radiometric systems
- Implement navigation algorithms in flight code (C++) and support SIL/HIL integration and testing
- Run Monte Carlo analysis to characterize navigation performance under dispersed and off-nominal conditions
- Generate navigation verification data across Impulse's suite of missions
- Support navigation operations including real-time orbit determination, console support, and anomaly response during critical mission phases
- Communicate navigation design needs, intent, performance, trades, and risk to the broader engineering team
Requirements:
- Bachelor's degree in engineering, science, or related field
- 5+ years of demonstrated experience in spacecraft navigation, orbit determination, or estimation
- Proficiency in Matlab and C++
- Demonstrated experience designing and implementing Kalman filters for rocket or space applications
