Junior Software Engineer Jobs in Carson, CA (NOW HIRING)

Lodestar's mission is to develop the first "Protect and Defend" capability for high-value space assets in orbit. Our flagship product, MITHRIL, is our hardware-agnostic, AI-enabled autonomy software suite that enables us 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 into single unified platform, we deliver an end-to-end, autonomous in-space superiority service.

At Lodestar, as a Software Engineer - On-board Autonomy, you'll be developing the decision-making systems at the heart of Lodestar's autonomy suite. You'll focus on creating algorithms that evaluate mission context, system capabilities, and environmental conditions to recommend and execute optimal actions. These models adapt dynamically to changing conditions, enabling real-time autonomous decision-making even in communications-limited or uncertain environments. Your work will bridge perception, prediction, and control, allowing spacecraft to operate intelligently, efficiently, and resiliently across complex mission scenarios.

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

• Design and implement on-board decision-making models that recommend and adapt strategies in real time
• Develop autonomous decision algorithms that integrate information from perception, state estimation, and intent prediction models to execute mission objectives
• Research and implement ML models for decision making - everything from lit. review, through training, to deployment
• Implement decision models that adapt dynamically to changing mission context, environmental conditions, and system status
• Develop frameworks for continuous re-evaluation of active strategies to ensure resilient and adaptive behavior under uncertainty
• Support real-time autonomy in communications-limited or time-critical scenarios
• Build and maintain autonomy infrastructure, testing frameworks, and deployment pipelines for space missions

• Bachelor's or Master's degree in Computer Science, Machine Learning, Robotics, a related field, or equivalent experience
• 2+ years of distinguished industry experience in autonomy, decision-making, or control systems for aerospace/robotics
• Strong proficiency in C++ and Python and DL frameworks (PyTorch, TensorFlow)
• Demonstrated experience with machine learning applied to decision-making or control problems
• Track record with optimal control, planning, or reinforcement learning in real-time systems
• Familiarity with multi-agent decision-making or planning under uncertainty

• Track record implementing autonomy applications in real-time or safety-critical environments
• Experience integrating perception and prediction outputs into decision frameworks
