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.

High-performance hardware requires high-performance processes. As our Senior Engineer Overall Integration (m/f/d), your mission is to optimize Q.ANT’s photonic integrated circuit (PIC) manufacturing flow, translating complex data into actionable insights to improve yield, stability, and process efficiency. You will drive cross-functional collaboration, develop tailored solutions, and build the tools that enable fast learning, reproducibility, and scalable production.

Your responsibilities

• Optimize and maintain the process of record (POR) for photonic integrated circuit (PIC) manufacturing to maximize yield, stability (Cp & Cpk), and product quality.

• Conduct root-cause analysis, implement corrective actions, and drive process improvements across PIC, Assembly, R&D, and Quality Management teams.

• Perform production trials (DoE) to align process windows, investigate interactions of processes, and integrate new processes, materials, or equipment.

• Develop and manage databases, user interfaces, and data-driven tools to enable process tracking, analysis, and decision-making.

• Collaborate across functions, driving communication and alignment between engineering, production, and quality teams.

• Identify cross-correlations and patterns in manufacturing data, proposing solutions that improve efficiency, reproducibility, and long-term scalability.

• Master’s degree in Data Science, Engineering, Physics, or a related technical field.

• Strong experience in Python, SQL, and database management systems.

• Proven ability to work cross-functionally, manage different technical needs, and translate complex data into actionable insights.

• Highly solution-oriented, self-driven, and capable of independent investigations to improve processes.

• Strong communication, collaboration, and ownership mindset; able to coordinate multiple stakeholders effectively.

• Fluent in English; German or another European language is beneficial.

• 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.
