Senior Production Engineer - System Integration & Test

Turning prototypes into production-ready systems requires more than lab innovation. It demands hands-on assembly, robust system integration, and rigorous testing to guarantee performance, reliability, and manufacturability. As our Senior Production Engineer (m/f/d), your mission is to assemble, integrate, and validate complex electro-optical and electronic-mechanical systems. You will establish stable test and integration processes, optimize workflows, and ensure small-series production ramp-up runs smoothly, enabling Q.ANT’s next-generation servers to be delivered on time and at scale. Your responsibilities Assemble, integrate, and test advanced photonic and electronic systems, ensuring repeatability, quality, and performance. Develop and standardize assembly sequences, test protocols, and production documentation to enable scalable manufacturing. Perform hands-on troubleshooting, root-cause analysis, and system-level debugging to prevent rework, yield loss, and field failures. Collaborate with R&D, quality, supply chain, and manufacturing to ensure smooth handover, test coverage, and integration readiness. Optimize workstations, tooling, and end-to-end test sequences to support efficient ramp-up from prototypes to small-series production. Drive continuous process improvement and quality assurance initiatives, including verification workflows, structured problem solving, and implementation of corrective actions.

Bachelor’s or Master’s degree in Electrical Engineering, Physics, Photonics, Optics, Microsystems Engineering, Mechatronics, or a related technical field. 5+ years of hands-on experience in system integration, testing, and verification of complex electro-optical or electronic-mechanical systems. Strong practical skills in optical and electronic assembly, hardware debugging, failure analysis, and system-level testing (DVT, PVT, SVT). Experience documenting test processes, verification instructions, and quality workflows for reproducible and scalable manufacturing. Desirable knowledge in high-speed digital and RF fundamentals, signal and power integrity, as well as basic automation or programming (Python preferred). Fluent in English; German or another European language is a plus. Why us? We hire for attitude and train for skills. We encourage self responsibility and accelerate professional development. We move fast and encourage experimentation. You have the opportunity to be part of developing breakthrough photonic computing technology and have a lasting impact on the future of computing. You can be part of a passionate international, highly skilled cross functional team. You will have access to the founders of the company.

Who we are and what we do Q.ANT is a deep-tech scale-up developing photonic processing solutions that compute natively with light and deliver a scalable alternative to transistor-based systems. The analog co-processors are optimised for complex computations and enable energy-efficient performance for next-generation AI and HPC applications. In collaboration with the Institute for Microelectronics Stuttgart IMS CHIPS, Q.ANT operates its own pilot line for photonic chips, based on the material system Thin-Film Lithium Niobate TFLN. Q.ANT was founded by Michael Förtsch in 2018 and is headquartered in Stuttgart, Germany.
