Lodestar is building the first autonomous AI fighter-pilot for space, to power in-orbit bodyguard satellites and deliver orbital defence as a service to high-value assets. Backed by Entrepreneur First.
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)
More about this role
Lodestar's mission is to develop the first "Protect and Defend" capability for high-value space assets in orbit. Our flagship product MITHRIL is the critical hardware & software necessary to augment any off-the-shelf spacecraft with the ability to autonomously detect, characterise, and reversibly neutralise orbital threats. By building on the proven space heritage of our best-in-class satellite-bus partners and fully integrating MITHRIL as a single platform, we deliver a fully autonomous end-to-end protection spacecraft service.

You'll develop high-fidelity sensor and environment models in Unreal Engine, stand up the software- and hardware-in-the-loop benches that our flight software runs against, and design the distributed services that let scenarios run reproducibly across machines and in CI. You'll work directly with the perception,...
