About The Position

At SBQuantum, we're redefining what's possible with quantum sensing. Our diamond-based quantum magnetometers unlock capabilities that conventional sensors simply cannot achieve, enabling applications ranging from GPS-denied navigation and public safety to aerospace and defense. Building the world's most advanced sensors is only half the challenge. We're equally focused on developing complete systems that turn quantum measurements into practical capabilities that solve real-world problems. Joining SBQuantum means transforming breakthrough technology into products that have never existed before. As part of a small, ambitious, and multidisciplinary team, you'll take ownership of meaningful technical challenges, collaborate with experts across physics, engineering, software, and product development, and see your work evolve from concept to deployment in demanding real-world environments.
