Senior Backend Engineer - Java (f/m/d)

at  Circus SE

OUR MISSION

At Circus (Xetra: CA1), headquartered in Hamburg with offices in Berlin and Munich, we are pioneering global developments in on-demand autonomous food production. Everything from creation to production and operation – enabled by seamlessly integrated cutting-edge robotics and transformative AI technology.
Our foundation rests in the extensive developments of groundbreaking robotics driven by artificial intelligence, previously the missing link in achieving true autonomous food automation. This is the moment for a new status quo: Just as autonomous driving will disrupt how we build cities, organize our days, and live our lives, so will we shift our whole reality around food.
Our Team is backing a paradigm shift in one of humanity’s most important sectors with the sharpest minds in Robotics, AI, Engineering and Culinary, collaborating closely with industry-leading partners to revolutionize every aspect of the food service experience.
Join us as we forge ahead, crafting a future where the art of cooking and the science of technology converge to create a world that thinks differently about food than it has for thousands of years—a world where food means something new.
