About The Position

SBQuantum is a seed-stage startup at the forefront of magnetic sensing innovation. Our vision is to unlock the full potential of magnetic intelligence through our proprietary quantum diamond technology. By combining diamond-based quantum sensors with advanced AI-driven software, we transform complex magnetic field data into actionable, high-value insights. Our solutions enable accurate magnetic mapping and object detection in environments where traditional sensing technologies—like GPS, radar, imagery, or sonar—cannot perform. From public safety and defence to space exploration, our multidisciplinary team of engineers, physicists, and data scientists is redefining how the world perceives magnetic signals—turning invisible complexity into clear, useful intelligence.

We’re a small, fast-moving, and ambitious team building something truly transformative. At SBQuantum, you’ll have the opportunity to shape cutting-edge quantum sensing technology from the ground up, collaborate with passionate experts across physics, data science, and engineering., and contribute directly to solving real-world challenges across critical industries.

We’re seeking a proactive and driven individual with experience in designing low noise, robust optomechanical systems in a startup environment. If you thrive in fast-paced, multidisciplinary environments and love working on hard problems with real-world impact, we’d love to meet you! Be part of the next generation of quantum sensing and data-driven innovation. Join SBQuantum and help us build the magnetic intelligence of tomorrow!
