At Orbital Paradigm, we design, develop, manufacture, and operate reusable orbital logistics systems. Our spacecraft perform multiple orbital mission profiles and return safely to Earth through hypersonic atmospheric reentry and landing with pinpoint accuracy for rapid refurbishment and reuse.

Role Description

We are looking for a Senior GNC Engineer to join the team in charge of the development, verification, and implementation of end-to-end guidance, navigation, and control capabilities for reusable orbital logistics vehicles.

The role covers the full GNC lifecycle, including mission analysis, trajectory design, guidance algorithms, navigation and estimation, control laws, flight dynamics, sensors and actuators modelling, simulation, verification, and support to flight software implementation. The engineer will work closely with systems, software, avionics, propulsion, aerodynamics, mechanical, and AIT teams to deliver robust GNC solutions across orbital operations, reentry, and landing.

This is a senior role requiring strong analytical depth, practical engineering judgment,



autonomy, and the ability to deliver high-quality GNC work from concept through simulation, implementation, testing, qualification, and flight operations.

Key Responsibilities
- Develop, validate, and improve end-to-end GNC architectures for reusable spacecraft missions.
- Develop guidance, navigation, estimation, and control algorithms for orbital operations, reentry, and landing phases.
- Perform mission analysis, trajectory design, flight dynamics analysis, and performance assessments.
- Develop and maintain simulation environments for GNC design, verification, and validation.
- Model spacecraft dynamics, sensors, actuators, environmental disturbances, uncertainties, and failure cases.
- Perform Monte Carlo simulation campaigns, robustness analyses, sensitivity studies, and performance verification.
- Develop and validate navigation and estimation algorithms, including Kalman filtering
