Cellula Robotics Ltd. is a world-leading marine technology company focused on changing the paradigm of subsea survey, science and security through modular, long range, autonomous underwater vehicle (AUV) systems.

Our products are configured for each client to deliver required capabilities to the end-user. We are committed to producing sustainable solutions for the defense, mineral exploration, and energy sectors driven by innovation and industry knowledge. We’re looking for enthusiastic and energetic people to join us in this growth and transition.

At Cellula we believe in collaboration, innovation, adaptability and reliability. These values are woven through all our products and how we do business. Our products are designed to be solutions to the challenges and capability needs of our clients, which often requires developing new capabilities and subsystems unique to a particular application. These systems are designed, built, and tested in-house by a skilled team of engineers, technicians, and support staff. People are at the heart of our business, and we pride ourselves in having a team-based workplace and building partnerships to solve the most difficult challenges in ocean technology. We believe in learning and innovating by doing. We send staff along with our products into the field to learn from our clients which informs our innovation.
