Senior Full-Stack Software Engineer

Why LeoLabs? At LeoLabs, we’re building the living map of activity in space. Through our proprietary global radar network and AI‑enabled analytics platform, we collect millions of measurements daily on more than 24,000 objects in low Earth orbit (LEO). Our radar‑powered intelligence protects billions in assets, monitors adversarial behavior, and ensures safe operations for commercial and government missions. We’re not just building technology, we are redefining global security, safety, and transparency in space. As orbital activity accelerates and threats grow more complex, LeoLabs is a trusted partner for Space Domain Awareness, Space Traffic Management, and Satellite Operations for top‑tier space operators and allied defense organizations. If you’re looking to work on mission‑critical challenges at the forefront of aerospace, national security, and AI, your impact starts here.
