Job description

About Lodestar

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 a single unified platform, we deliver an end-to-end, autonomous in-space bodyguarding service.

Preferred Skills & Experience

• Experience designing carrier boards for Linux-based SoCs.
• Familiarity with NVIDIA SoCs.
• Hands-on experience with FPGA design and integration.
• Proficient with PCB simulation workflows, including signal integrity, power integrity, and EMC/thermal analysis.
• Background in space-rated electronics and high-reliability design practices, including radiation effects analysis, fault-tolerant architectures, and qualification processes for space systems.

Benefits

• Competitive Salary (based on experience)
• Equity pool options
• Vibrant, open-plan office in London
• 28 Days Annual Leave
• Private Medical Insurance
• Be part of a scrappy, dynamic, multidisciplinary, collaborative crew 🏴☠️
