GNC Simulation Engineer

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.
