• Entrepreneurial mindset, with strong analytical skills, commercial judgment, attention to detail, and independent thinking.
• Strong communication skills and ability to explain quantitative findings clearly to both technical and non-technical stakeholders.

Good to Have

• Experience developing execution algorithms, market impact models, or liquidity forecasting models.
• Experience with broker / venue analysis, algo wheel analytics, post-trade TCA, or execution benchmarking.
• Familiarity with internal crossing, central risk book, market making, inventory optimization, or risk warehousing strategies.
• Prior financial markets experience, particularly in equities or electronic trading.
