About Us

At SBQuantum were redefining whats 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 worlds most advanced sensors is only half the challenge. Were 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 youll 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.

Who Were Looking For

Were seeking a proactive and driven individual with experience in startups or the inertial/magnetic navigation sector to help us strengthen our software capabilities and shape the future of our technology. If you thrive in fast-paced multidisciplinary environments and love working on hard problems with real-world impact wed love to meet you!

The Role

As a Full-Stack Software Developer youll develop the complete software ecosystem behind SBQuantums products from sensor communication and onboard data processing to customer-facing desktop mobile and cloud applications.

Working alongside product managers data scientists robotics engineers and fellow software developers youll help build the next generation of intelligent sensing systems that transform cutting-edge quantum sensing technology into practical real-world solutions.

Youll take ownership of major software components throughout their lifecycle. As part of a new product development effort youll have the opportunity to influence technical decisions and software architecture while helping define the foundation of products from prototype to deployment.

What Youll Do

• Develop the complete software stack behind SBQuantums products from sensor communication and onboard processing to desktop mobile and cloud applications.
• Design and implement robust maintainable software architectures that support products from prototype to deployment.
• Develop hardware communication layers device drivers communication protocols APIs and ROS nodes to interface with quantum sensors and onboard systems.
• Build backend services and cloud infrastructure using Python and AWS.
• Develop customer-facing applications for system configuration diagnostics visualization mission planning and data management.
• Process analyze and visualize real-time sensor data from navigation and sensing systems.
• Develop APIs and SDKs that enable customers to integrate SBQuantum products into their own software ecosystems.
• Collaborate closely with product managers data scientists robotics engineers firmware developers and hardware engineers to deliver complete systems.
• Participate in code reviews automated testing CI/CD and continuous improvement of our software development practices.

What Were Looking For
