  • Monitor and manage execution quality, transaction costs, and market risks arising from changing market regimes and small statistical effects.
  • Work closely with quantitative researchers to enhance tooling, frameworks, and shared feature libraries.
  • Take ownership of system components in a fast-paced, agile environment, working both independently and collaboratively as required.
  • Participate in live trading support, including interaction with orders and brokers as part of a rota (FCA certification required).

  • Comfortable tackling complex, ambiguous problems with limited oversight.
  • Collaborative mindset with the ability to work closely with researchers, technologists, and trading operations.
  • Calm and reliable under pressure, particularly in live trading environments.
