  • Multi-asset indices - transparent benchmarks that bridge traditional and digital assets, covering equities, crypto and even gold.
  • Capital-markets & treasury desk - a front-office team that designs low-latency trading tech, manages group liquidity and provides execution services to every business line.

  • Direct route to Head of Engineering as the platform grows.
  • High-velocity delivery culture: decisions in minutes, releases in days, not quarters.
  • Top-tier comp: base, bonus and full benefits.
What you will do
  • Architect and deliver low-latency market-data and execution services from scratch.
  • Stay deeply technical while mentoring a small squad of engineers.
  • Embed with traders to iterate quickly on new features and strategies.
