£50,000–£85,000 + benefits
UK Passport required - eligible for MOD clearance
Standard 8 is recruiting a Senior Java GUI Developer for a defence engineering team building real-time, high-data systems used in live operational environments.
This is not web apps. It’s performance-heavy software, complex GUIs and systems that have to work first time.
The Job
You’ll join an experienced Java team developing desktop applications for data-intensive, mathematically heavy systems.
Day to day:
*Building Java applications with JavaFX or Swing
*Working in Linux environments
*Contributing to real-time processing systems
*Getting stuck into C++ where needed
*Testing properly, not just hoping for the best


What You Need
*5+ years’ Java background software engineering experience
*Solid GUI development using JavaFX or Swing
*Some C++ experience (at least a year)
*Experience with real-time or high-throughput systems
*Comfortable working on Linux
You’ll need to be methodical, adaptable and take pride in your work. No hand-holding.
Nice to Have
*Linux optimisation and deployment experience
*Networking fundamentals (IP protocols, Ethernet configuration)
*Low-level Linux or driver interfacing
*DSP, signal or image processing knowledge
Non-Negotiables
*UK national with a valid UK passport
*Relevant degree (or equivalent technical background)
If you’re an experienced engineer who prefers serious technical work over corporate theatre, we should speak.
