Overview
Karman+ is a team of engineers, scientists, designers, and innovators building spacecraft systems to operate in harsh environments. We design and test guidance, navigation, and control (GNC) systems using high-fidelity simulations that capture interactions between spacecraft, environment, and control algorithms.
We are seeking a GNC Simulation Engineer to design, develop, and maintain simulation frameworks that inform spacecraft design decisions, mission planning, and system verification. This role collaborates with GNC, flight software, and vehicle engineering teams to ensure spacecraft are controllable, robust, and mission-ready.
Position

What you'll do
- Design, implement, and maintain 6-DoF spacecraft simulations including dynamics, sensor models, and environment effects
- Develop Monte Carlo pipelines, sequencers, and visualization tools to evaluate vehicle controllability and performance
- Support flight software integration by implementing, testing, and validating GNC algorithms in simulation environments
- Work with multidisciplinary teams to evaluate design trades and their impact on vehicle controllability and stability
- Develop interfaces between simulation frameworks and hardware-in-the-loop testbeds
- Ensure simulation verification and validation against analytical models and test data
- Present analysis results and make clear recommendations on vehicle design and mission concepts
- Contribute to CI / CD and automation pipelines for simulation and test workflows
- Collaborate with external partners, academia, and customers on simulation requirements and outcomes
