Standard 8 is recruiting a Senior Java/C++ GUI Developer for a defence engineering team building real-time, high-data systems used in live operational environments.

Day to day:

  • Building Java applications with JavaFX or Swing

  • Working in Linux environments

  • Solid GUI development using JavaFX or Swing

  • Some C++ experience (at least a year)

  • Experience with real-time or high-throughput systems

  • 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.
