Senior Java GUI Developer - MOD/Defence

Senior Java Developer – Defence Systems

Surrey - 5 days onsite

£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.
