Your mission
The future of AI computing is light, not electrons.
Q.ANT is building photonic processing systems that compute with light – delivering a scalable, energy-efficient alternative to transistor-based architectures for next-generation AI and HPC applications.
Turning prototypes into scalable, production-ready systems requires more than innovation in the lab. It requires precise optical assembly, robust system integration, and rigorous testing to ensure high performance and reliability.
As our Senior Production Engineer (m/f/d) , your mission is to assemble, integrate, and validate advanced photonic and electronic systems. By standardizing workflows, optimizing processes, and troubleshooting at the system level, you ensure that Q.ANT’s next-generation servers are manufacturable, high-performing, and delivered on time.
