Master Thesis: Phase 2 – Advanced HMI Development and System Integration for Industrial X-ray system

**Master Thesis: Phase 2 – Advanced HMI Development and System Integration for Industrial X-ray Inspection Systems** **Start:** From July 2026 or by arrangement **Background** XRAY-LAB GmbH \& Co. KG develops industrial X-ray and CT inspection systems used for non destructive testing (NDT). As part of an ongoing software platform development, the Human-Machine Interface (HMI) for the X-ray inspection machine is being implemented in multiple phases. **Phase 1 of the HMI development has already been completed** as part of a previous Master’s thesis and delivered a functional, industrial-grade HMI foundation. This **Phase 2 Master’s thesis** builds directly on that foundation and focuses on advanced HMI features, imaging tools, calibration workflows, maintenance functions, and extended PLC communication. **Your Thesis Topic** The objective of this thesis is to extend and enhance the existing HMI with advanced functionality, focusing on usability, imaging quality, calibration, maintenance, and scalable communication. **Your Tasks** * Extend the existing HMI framework for industrial X-ray inspection systems with advanced imaging tools (filters, histogram analysis, line pro * Design and implement multi-mode calibration workflows with interactive visualization of calibration results. * Enhance the HMI with extended maintenance and service functions, including diagnostic views, system monitoring, and structured event logging. * Align manipulator hardware concepts with HMI control and visualization, ensuring intuitive operator interaction (X, Y, Z axes; tilt/rotation support optional). * Expand PLC communication using OPC UA and optionally other communication protocols to support multiple industrial PLC vendors. * Implement modular, maintainable software architecture for the HMI with focus on usability, scalability, and documentation. * Validate implemented features against defined HMI requirements and produce clear documentation for software structure, workflows, and communication interfaces. * Support integration testing with existing Phase 1 HMI features and connected hardware modules and converting it to .NET 10 from .NET 8\. **Your Profile** * Ongoing Master’s degree in Electronics, Mechatronics, Computer Science, or a related technical field. * Basic experience with SPS/PLC programming (Siemens TIA Portal, Beckhoff TwinCAT, or equivalent). * Basic understanding of Databases (SQLite) and communication protocols like OPC UA/ADS. * Experience with C#, .NET, C\+\+, or similar technologies is a plus * Interest in industrial automation, control systems, and human-machine interfaces. * Structured, independent working style with interest in applied industrial research * Proficient German and English language skills are required. **Application Details** Please send your application including CV, Cover Letter, Certificate of enrollment, Current grade transcript, and Relevant certificates in one zipped file. **Contact** For questions regarding the position or the application process, please contact: * Andre Dinkel: personalwesen@xray-lab.com * Dirk Banhart: dirk.banhart@xray-lab.com Job Types: Internship, Contract Contract length: 6 months Pay: 550,00€ - 600,00€ per month Work Location: Hybrid remote in 75447 Sternenfels
