Visualization Skills: Proficiency with charting libraries (e.g., D3.js, Highcharts) to visualize market trends and portfolio analytics.
Financial Domain Knowledge: Direct experience in capital markets, wealth management, or fintech is a significant advantage. You should be familiar with blotters, order entry, and real-time execution workflows.

Stability with Flexibility: 6-month full-time contract with a specific strategic intent to extend long-term for high performers.
Cutting-Edge Stack: Work with the "gold standard" of fintech tools (OpenFin, AG Grid) on a platform that moves the needle on global markets.
Toronto Financial District: 2 days per week onsite at a premier financial hub, offering the best of hybrid flexibility and professional collaboration.
