Junior Software GUI Engineer

The Role

In this role, you will be responsible for developing intuitive, reliable, and maintainable Windows desktop applications using modern Microsoft technologies. You will work across a diverse portfolio of software solutions, including customer-facing user interfaces, service and diagnostic tools, production and manufacturing test applications, and advanced engineering tools such as emulators and simulators.

Working as part of a multidisciplinary engineering team, you will contribute throughout the entire software development lifecycle, from concept and architecture through implementation, verification, release, and long-term product support. This is an excellent opportunity to work on highly technical products that combine software, electronics, optics, firmware, and systems engineering.

What you will be doing...

Software Design & Development

• Design, develop, and maintain Windows desktop applications using C#, WPF, XAML, and .NET.

• Develop software using the MVVM (Model-View-ViewModel) architectural pattern to create scalable, maintainable, and testable applications.

• Create customer-facing user interfaces that allow users to configure, monitor, and control laser systems.

• Develop service and diagnostic applications used by field service engineers for troubleshooting and support.

• Design production and manufacturing test GUIs that enable efficient system build, calibration, and verification activities.

• Develop engineering tools, including emulators, simulators, and virtual laser systems that replicate product behaviour and support development before hardware is available.

Software Architecture & Reuse

• Develop reusable software components, shared libraries, and NuGet packages to drive consistency across multiple product platforms.

• Contribute to software architecture decisions, coding standards, and development best practices.

• Support the standardisation of software frameworks and user experience across the organisation.

System Integration

• Integrate GUI applications with embedded firmware, hardware devices, and third-party equipment.

• Work with a range of communication protocols including serial communications, USB, Ethernet, and industrial communication interfaces.

• Collaborate closely with firmware, systems, electronics, applications, and product engineering teams to define interfaces and deliver integrated solutions.

Testing & Product Support

• Participate in all phases of the software lifecycle including requirements definition, design, implementation, testing, release, and maintenance.

• Perform software verification, debugging, issue investigation, and defect resolution.

• Contribute to test planning and ensure software quality before release.

• Support product release activities, ongoing maintenance, and continuous improvement initiatives.
