Senior Integration Engineer (m/f/d)

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.

High-performance hardware requires high-performance processes. As our Senior Integration Engineer (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 semiconductor 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.

Your profile

• 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.
