Job Description

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.
