Job description

C# Software Developers

• Work on Next-Gen Defence Simulations £60K + Bonus 3 to 4 days on site, Stevenage

A fantastic opportunity for a C# Developer with a passion for defence and cutting-edge simulation technology to join a leading Defence organisation. You'll be helping to shape the next generation of weapon system simulations.

Due to the nature of the work, candidates must be willing and able to go through security clearance at SC level (must have lived in the UK for the last 5 years).

This role sits within the Weapon Systems Simulation & Experimentation (WSSE) team who play a crucial role in how weapon systems are designed, tested, and brought to life. They’re involved throughout the entire product lifecycle, from early concept development right through to training and in-service support. It’s where software, hardware, and innovation come together to create realistic and reliable simulation environments that help deliver safer, smarter, and more effective systems.

In this varied role you could be:

• Developing high-performance software (C#/C++) for real-time simulation systems
• Integrating software and hardware components to simulate complex weapon systems
• Using agile Scrum methodologies to deliver capability in rapid, iterative cycles
• Supporting visualisation, experimentation, and training activities for advanced defence solutions

To secure the role you will have a proven track record of:

• C# and/or C++
• Real-Time Software
• Configuration control
• Continuous Integration and Continuous Delivery or Deployment
• Unit testing and test-driven development
• Agile development

Experience in defence, aerospace, or simulation environments would be a big advantage but not essential.

If you’ve got a background in C# or C++, and experience with real-time software, configuration control, or CI/CD, then this could be the opportunity you're looking for.
