Java Backend Engineer (Legacy Systems)

  • Location: Madrid, Madrid, Spain
  • Remote: Hybrid
  • Type: Permanent
  • Job #26090

Madrid’s about to switch back on after summer — and if you’re coming back from holiday thinking “new season, new move”… this is a strong one.

We’re hiring a hands-on Java Engineer to work on a mission-critical, real-world platform running on Java 7 / Java 8. This is not greenfield hype. It’s production engineering: stability, performance, clean refactoring, and careful delivery.

Location: Madrid (hybrid – 50% in office)
Type: Permanent
Language: Spanish (daily working), English (conversational)

What you’ll be doing

  • Building and maintaining backend services in Java 7/8
  • Debugging incidents, improving performance, and shipping safely in production
  • Working in a mature codebase with pragmatic refactors, clean code, and sensible testing
  • Collaborating closely with a Madrid-based engineering team

What we’re looking for

  • Strong commercial experience with Java 7 and/or Java 8 (this is essential)
  • Solid backend fundamentals (APIs, data access, reliability, troubleshooting)
  • Comfortable working in legacy constraints with a calm, methodical approach
  • Based in Madrid or open to relocating

Why it’s worth a look

  • High-impact systems people actually rely on
  • A role for engineers who like depth over buzzwords
  • Good timing: fresh pipeline needed for mid-August client review
