Job description

The Role

This is your chance to join a high-impact engineering team within one of the world’s most respected investment banks. You’ll be building scalable, real-time systems from the ground up—no legacy code, no red tape. Just clean architecture, modern tools, and a team that knows how to ship.


Why Developers Are Making the Jump

  • Massive earning potential: This position offers the chance to double—or even triple—your current income.

  • No dead weight: You’ll be surrounded by top-tier talent from global tech firms

  • Modern stack: Cloud-native, event-driven, containerized. No outdated tech, no excuses.

  • Real impact: Your code won’t sit in a backlog. It’ll power global financial infrastructure.


What You’ll Leave Behind

  • Legacy codebases that fight you at every turn

  • Teams that settle for “good enough”

  • Salary ceilings that don’t reflect your value

  • Projects that never launch or never matter


What You’ll Gain

  • A contract that pays what you’re worth

  • A team that pushes you to be better

  • A tech stack that keeps you sharp

  • A brand name on your CV that opens doors globally


What you'll need:

  • Tech: Java (5+ years), Spring Boot

  • Mindset: Team player, collaborative mindset
