Senior Windows GUI Developer

Job Title: Senior Windows GUI Developer (Contract)

Duration: 6–8 weeks (potential extension)

About the Role

A leading engineering contractor near Reading is looking for a Senior Desktop Developer to build a standalone Windows GUI application completely from scratch.

You will own the end-to-end delivery of a tactical navigation interface—functioning like a specialized "Sat Nav" console—that allows operators to input geographic coordinates and send route command data directly into a flight control system.

Because this is a short, high-impact sprint, you will need to work autonomously, set up the project architecture, and deliver a reliable, working application within a 6–8 week window.

Key Requirements

• Proven experience building standalone Windows Desktop GUIs from scratch.
• any Language-agnostic background: Open to C# / WPF , C++ / Qt , Python , or Electron OR Java , provided it delivers a smooth, native Windows desktop application.
• Experience handling inputs/communications over standard protocols (e.g., Serial, Sockets, TCP/UDP).
• Familiarity with geographic/coordinate data (lat/long, mapping, or waypoint inputs) is a major plus.
• Ability to work independently and deliver fully functional software with minimal hand-holding.
