What We are Looking For: You will need to have solid experience, with the full software development lifecycle—from concept and design through to testing and deployment. We are looking for someone who can hit the ground running, contribute ideas, and enjoy being part of a collaborative, solution-focused team.

• Excellent communication skills, both written and verbal
• A proactive mindset, with the ability to take ownership and manage your own workload
• A genuine team player, who enjoys collaborating and contributing to group success

Core Technical Skills Required:

• Solid experience with C# and the .NET framework, with the confidence to build clean, maintainable code
• Solid experience with relational database design , in particular with SQL Server, with a thoughtful approach to data structure and performance

Desired Experience With (some, but not all):

• 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
• Mobile app development, particularly with Xamarin or .NET for Android
• 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
• AI-enhanced development, such as using GitHub Copilot, coding with AI tools, or even training models

What You will be Doing

• 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
• Participating in code reviews and sharing knowledge with other team members

Occasionally liaising with internal stakeholders, or customers to clarify requirements or support installations and upgrades
