Software Engineer – C# / WPF / Mathematical Problem-Solving

Company Overview

Global Inkjet Systems (GIS) is a world leader in industrial inkjet technology, developing advanced software, electronics, and components for high-performance digital printing. Our solutions drive cutting-edge applications, including high-speed packaging, direct-to-shape printing, 3D printing, printed electronics, and advanced materials deposition.

Inkjet printing is a highly complex and multi-disciplinary field, requiring expertise in fluid dynamics, signal processing, precision motion control, and real-time data processing. Our software plays a critical role in controlling high-precision printheads, optimising drop placement at microscopic scales, and ensuring seamless integration with industrial automation systems.

Role Overview

As a Software Engineer at GIS, you will develop high-performance software solutions in C# and .NET, working on projects that demand precision, efficiency, and real-time processing. You will be responsible for designing WPF-based user interfaces, implementing REST API architectures, and optimising multi-threaded and parallel processing algorithms.

This is an opportunity to apply mathematical modelling, computational algorithms, and physics-based problem-solving to real-world industrial challenges. Your work will directly contribute to advancing drop placement accuracy, motion control algorithms, and high-speed image rendering—key factors in the next generation of digital printing technologies.

This role is suited to candidates with a strong mathematical and computational mindset who enjoy applying problem-solving techniques to complex engineering challenges.

• Develop and maintain software applications using C# and .NET, ensuring efficiency, scalability, and robustness.
• Design and implement WPF-based user interfaces, focusing on usability, performance, and complex data visualisation.
• Build and integrate REST API client-server applications, ensuring secure and efficient communication.
• Work with thread-safe and parallel programming architectures, including multi-threading and asynchronous processing.
• Apply mathematical modelling, numerical methods, and physics-based algorithms to enhance printhead control, ink flow dynamics, and image processing.
• Collaborate with engineers and scientists to optimise real-time data processing and high-precision motion control in industrial printing systems.
• Manage technical specifications and requirements across multiple projects, meeting deadlines effectively.

Why a Mathematics or Physics Background Matters

Inkjet printing is more than just software development—it’s about understanding how tiny droplets of ink behave at microsecond timescales. At GIS, our software controls high-speed industrial printheads, requiring precision in:

• Fluid dynamics – modelling how ink moves through microscopic nozzles.
• Signal processing – ensuring accurate drop placement and colour reproduction.
• Algorithm optimisation – improving image rendering, motion control, and real-time corrections.
• A background in mathematics or physics provides the critical problem-solving and analytical skills necessary to develop and refine these complex systems.

• Degree in Mathematics, Physics, Engineering, or a similar numerate discipline.
• Strong proficiency in C# and the .NET framework.
• Extensive experience in WPF UI development, ideally using MVVM design patterns.
• Knowledge of network programming (HTTP, TCP/IP, Sockets) and data transmission protocols.
• Strong analytical and problem-solving skills, with a methodical approach to software design.
• Ability to work independently and manage complex technical challenges.
• Enthusiasm for technology, with evidence of self-directed learning and technical development.
