Software Engineer I: Perception

About Lodestar

Lodestar's mission is to develop the first "Protect and Defend" capability for high-value space assets in orbit. Our flagship productMITHRILis 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 integratingMITHRILas a single platform, we deliver a fully autonomous end-to-end protection spacecraft service.

About the Job

As a Software Engineer I - Perceptionat Lodestar, you’ll be joining the perception and machine vision teams to rapidly grow our vision and perception models atMITHRIL’scenter.

You'll help build and refine algorithms that detect, classify and understand unknown space targets in real time. Working alongside senior perception engineers, you'll combine computer vision, image processing and machine learning to develop the custom models that underpin autonomous decision-making in complex and uncertain space environments.

This is an early-career role. We're looking for strong fundamentals and fast learning rather than a long track record, and you'll be given real ownership early with the support to grow into it.

We proudly have an "extreme ownership" oriented engineering culture.

What You’ll Do

• Contribute to the perception system at the core of Lodestar's autonomy software suite
• Work through the full lifecycle of perception algorithms alongside senior engineers including literature review, training, evaluation, optimisation and deployment
• Build on and optimise our existing models for edge computing, and develop new components with guidance from the perception leads
• Help develop and test our methods for predicting the relative pose of dynamic space targets in harsh and unpredictable visual environments
• Integrate perception models into mission simulation environments and real-time autonomy pipelines
• Contribute to the design of realistic sensor models and digital twins to improve perception fidelity in mission scenarios
• Maintain and extend our perception tooling, model training infrastructure, and evaluation frameworks
• Collaborate across the autonomy, estimation, and mission software teams to support perception fidelity, performance, and scalability
