Core Technical Skills Required:

• Solid experience with C# and the .NET framework, with the confidence to build clean, maintainable code

• Desktop application frameworks, such as WPF, WCF, or UWP
• Entity Framework Core or other ORMs for data access
• Azure or other Cloud platforms—especially with an eye towards future deployments
• Clear, structured technical documentation, from design specs to testing materials

• Hardware integration, including ESP32 microcontrollers or PLCs
• Source control using Git and collaborating via branches, pull requests, and versioning workflows
• SQL Server Management Studio (SSMS) for working with relational databases
• Strong interpersonal skills—interpreting customer needs, supporting users, and clearly communicating ideas within the team

• Contributing to the design and development of new software products and R&D projects
• Maintaining and modernising legacy systems by converting them to C# .NET
• Working across the full development lifecycle
• Collaborating with cross-functional teams
• Supporting the continuous improvement of development practices, tools, and workflows
