## About the role

At Lodestar, as a Software Engineer: Simulation , you'll build the environment in which MITHRIL is developed, tested and proven. Every autonomy behaviour we fly is validated in simulation first, which makes the simulator one of the highest-leverage pieces of software in the company: if it isn't faithful, nothing downstream can be trusted.

## What they're looking for

- Familiarity with orbital mechanics and Basilisk
- Experience with physics engines and rigid-body dynamics
- Sensor modelling experience across electro-optical, LIDAR, RADAR, or RF sensors
- Experience with GPU rendering pipelines or CUDA for accelerated simulation and synthetic data generation
- Exposure to robotics or space simulation frameworks such as Gazebo, Isaac Sim, Basilisk, or 42
- Experience with distributed transports (DDS, Zenoh, gRPC) and time-synchronisation protocols (PTP, NTP)
